Question
I give him Kitten Chow that he will only eat if he has to. Won't eat any "off brand" can food like my other cats ate...so I buy Fancy Feast, and now he's not eating that!

He also pukes once in a while....????

Answer
Becky,

Through experience I've found that some cats who are fussy about their food tend to respond well to higher quality foods. Fancy Feast and Kitten Chow aren't high quality foods and they contain a lot of grains and by-products, the vomiting can be the result of a sensitivity to one or more ingredients in these foods and since the ingredient list changes based on what's cheapest at the time that lot is manufactured there's no way to know for sure what is causing the problems. I'm not a fan of feeding low quality commercially produced foods, especially since the Menu Foods catastrophe which caused many animals to become sick and cost thousands of pets their lives. I lost a lot of faith in the pet food industry after my eldest cat almost lost her life to kidney failure during the problems with Menu Foods, I was shocked and really thought that I was providing my cats with a decent quality food. My veterinarian referred me to a site that's got information about what cats actually need in terms of their diet to live longer and healthier lives, the information on this site is provided by a veterinarian who is concerned about the quality of many commercially produced pet foods and the health consequences that a poor quality diet can cause. The web address is catinfo.org. If you aren't comfortable with feeding the diet suggested on this site you may want to try high quality, holistic cat foods made with human grade ingredients, the two brands that I'm aware of that fit this description are Wellness and Spot's Stew by Halo. Wellness is designed to be fed as a combination of canned and dry food which can become a bit expensive given the quantities recommended. I feed a combination of a homemade raw diet and Spot's Stew Sensitive Cat by Halo, this formula is meant for cats with sensitive tummies or skin problems. The ingredient list for Spot's Stew Sensitive Cat is as follows: Turkey, Pea Protein, Whole Dried Eggs, Oats, Pearled Barley, Pea Flour, Turkey Liver, Salmon, Flaxseed, Salmon Oil, Pea Fiber, Sweet Potatoes, Apples, Blueberries, Green Beans, Carrots, Cranberries, Zucchini, Alfalfa, Inulin, Calcium Sulfate, Potassium Chloride, Taurine, Salt, Folic Acid, Zinc Proteinate, Iron Proteinate, Cobalt Proteinate, Copper Proteinate, Manganese Proteinate, Vitamin A Supplement, Vitamin D3 Supplement, Vitamin E Supplement, Choline Bitartrate, Niacin, Pantothenic Acid, Ascorbic Acid, Riboflavin Supplement, Thiamine Mononitrate, Pyridoxine Hydrochloride, Biotin, Lactobacillus Acidophilus, Bifidobacterium Longum, Enterococcus Faecium, Lactobacillus Plantarum, Calcium Iodate, Sodium Selenite. There are several advantages to feeding a high quality diet. Cats who tend to suffer from stomach upsets like vomiting or diarrhea often improve dramatically. A higher quality diet means that the cat needs to eat less to meet his nutritional needs properly. Often cats starting out on a high quality diet will show improvement in the health of their coats and energy levels. Due to the fact that most cats will require less of a high quality food they will also visit the litter box less frequently and there's the added bonus that the contents of the litter box will have a much less offensive odor. Overall while the cost of lower quality foods may initially seem like a bargain this isn't the case long term, cats who eat a substandard diet will be more likely to develop serious health problems. I've learned over the years that a pet parent can choose to pay a bit more for a higher quality food or they can wait and pay more at the vet's office. A 6 lb bag of Spot's Stew Sensitive Cat by Halo costs about $25 CAN and lasts my three resident cats for about a month.

I have taken the liberty to include a rather eye opening article that I think somewhat sums up the dirty little secrets of the pet food industry. Sadly although many pet food manufacturers claim that they have included nothing but the best and healthiest ingredients this is usually not the case. Often times ingredients change without notice based on what’s cheapest at that time, especially when you are talking about the cheaper foods commonly sold in grocery stores. I have done my own research into making homemade food for my cats although I must say that this can be a rather expensive and time consuming option due to the fact that cats are obligate carnivores and their nutritional needs are fairly complex. Unfortunately getting a diet wrong could cost a cat their life or cause very serious health problems so I'd recommend doing extensive research, speaking to your veterinarian and spending some time looking at published pet cookbooks that focus on cat diets.

I found the article below on a pet care website - bear in mind this article hasn’t been checked for accuracy, it sums up a general view of many pet foods claiming to be “nutritionally complete” or “whole food that your pets need” that market their product in grocery stores with minimal cost. Another revealing fact is that many pet food manufacturers don’t manufacture pet food as their primary product - for instance Procter and Gamble makes Eukanuba and Iams pet foods - they also make soap, shampoo, household cleaners, personal hygiene products like anti-perspirant….Given that their primary focus isn’t on manufacturing a whole pet food with ingredients designed to promote optimum health I have concerns about their food and the potential for other products to end up inside a bag of pet food just as they did during the recent Menu Foods recall of most pet food brands as a result of pets becoming seriously ill and dying because there were ingredients like melamine found in a substandard ingredient from China.

“Whole chickens, choice cuts of beef, fresh grains and all the wholesome nutrition your dog or cat will ever need.”

These are the images pet food manufacturers promulgate through the media and advertising. This is what the $10 billion per year U.S. pet food industry wants consumers to believe they are buying when they purchase their products.

This report explores the differences between what consumers think they are buying compared to what they are actually getting. This document focuses in very general terms on the most visible name brands -- the pet food labels that are mass distributed to supermarkets and grocery stores -- but there are many smaller, more highly respected brands that may be guilty of the same offenses.

What most consumers are unaware of is that the pet food industry is an extension of the human food industry, also known as the agriculture industry. Pet food provides a place for slaughterhouse waste and grains considered "unfit for human consumption" to be turned into profit. This waste includes cow tongues, esophagi, and possibly diseased and cancerous meat. The "whole grains" used have had the starch removed and the oil extracted -- usually by chemical processing -- for vegetable oil, or they are the hulls and other remnants from the milling process. Some of the truly whole grains used may have been deemed unfit for human consumption because of mold, contaminants, or poor storage practices.

Four of the five major pet food companies in the United States are subsidiaries of major multinational food production companies: Colgate-Palmolive (Hills Science Diet Pet Food), Heinz (9 Lives, Amore, Gravy Train, Kibbles n Bits, Recipe, Vets), Nestle (Alpo, Fancy Feast, Friskies, Mighty Dog) and Mars (Kal Kan, Mealtime, Pedigree, Sheba). From a business standpoint, multinational food companies owning pet food manufacturing companies is an ideal relationship. The multinationals have a captive market in which to capitalize on their waste products, and the pet food manufacturers have a reliable source from which to purchase their bulk materials.
There are hundreds of different pet foods available in this country. And while many of the foods on the market are virtually the same, not all of the pet food manufacturing companies use poor quality and potentially dangerous ingredients.

Ingredients

Although the purchase price of pet food does not always determine whether a pet food is good or bad, the price is often a good indicator of quality. It would be impossible for a company that sells a generic brand of dog food at $9.95 for a 40-lb. bag to use quality protein and grain in its food. The cost of purchasing quality ingredients would be much higher than the selling price.
The protein used in pet food comes from a variety of sources. When cattle, swine, chickens, lambs, or any number of other animals are slaughtered, the choice cuts such as lean muscle tissue are trimmed away from the carcass for human consumption. Whatever remains of the carcass -- bones, blood, pus, intestines, ligaments, and almost all the other parts not generally consumed by humans -- is used in pet food. These "other parts" are known as "by-products" or other names on pet food labels. The ambiguous labels list the ingredients, but do not provide a definition for the products listed. (See the API Pet Food Shopping Guide for a more detailed list of ingredient definitions.)

The Pet Food Institute -- the trade association of pet food manufacturers -- acknowledges the use of by-products in pet foods as additional income for processors and farmers: "The purchase and use of these ingredients by the pet food industry not only provides nutritional needs for pets at reasonable costs, but provides an important source of income to American farmers and processors of meat, poultry and seafood products for human consumption.
Many of these remnants are indigestible and provide a questionable source of nutrition for our animals. The amount of nutrition provided by meat by-products, meals, and digests can vary from vat to vat. James Morris and Quinton Rogers, two professors with the Department of Molecular Biosciences, University of California at Davis Veterinary School of Medicine, assert that, "There is virtually no information on the bioavailability of nutrients for companion animals in many of the common dietary ingredients used in pet foods. These ingredients are generally by-products of the meat, poultry and fishing industries, with the potential for a wide variation in nutrient composition. Claims of nutritional adequacy of pet foods based on the current Association of American Feed Control Officials (AAFCO) nutrient allowances ('profiles') do not give assurances of nutritional adequacy and will not until ingredients are analyzed and bioavailability values are incorporated.

Another source of meat you won't find mentioned on pet food labels are dogs and cats. In 1990 the San Francisco Chronicle reported that euthanized companion animals were being used in pet food. Although pet food manufacturers vehemently denied the report, the American Veterinary Medical Association confirmed the Chronicle's story.  

Many pets are euthanized with sodium pentobarbital and then rendered.  This poison does not break down and goes into commercial pet food and feed for cows, pigs and horses.  I must admit that this point has been made many times over many years - if it’s true that has to be one of the scariest things to consider in the case for making high quality food for pets and livestock from ingredients that we would actually consider eating. When you think about this it makes you question the safety of many common foods found in the average human diet - after all, if these ingredients are making into food used to feed livestock are they ultimately making it into the human food chain?For the detailed report by the FDA's Center for Veterinary Medicine on popular commercial pet foods containing pentobarbital, click here.  When you read the report, please know that AD (animal digest) is animal waste (to be polite)!

Protein is protein once it is rendered. What is rendering?

Rendering, as defined by Webster's Dictionary, is "to process as for industrial use: to render livestock carcasses and to extract oil from fat, blubber, etc., by melting."

What can the feeding of such ingredients do to your companion animal?

Some veterinarians claim that feeding slaughterhouse wastes to animals increases their risk of getting cancer and other degenerative diseases. One factor is that the cooking methods used by pet food manufacturers and rendering plants do not destroy many of the hormones used to fatten livestock, or medications such as those used to euthanize dogs and cats.  

Animal and Poultry Fat

You may have noticed a unique, pungent odor when you open a new bag of pet food -- the smell of restaurant grease from a hundred fast food restaurants. What is the source of that delightful smell? It is refined animal fat, kitchen grease, and other oils too rancid or deemed inedible for humans.

Restaurant grease has become a major component of feed grade animal fat over the last fifteen years. This grease, often held in fifty-gallon drums, is usually kept outside for weeks, exposed to extreme temperatures with no regard for its future use. The next few times you dine out, be sure to look out back behind the restaurant for a container with a rendering company's name on it. It is almost guaranteed that you will find one. "Fat blenders" or rendering companies then pick up this rancid grease and mix the different types of fat together, stabilize them with powerful antioxidants to retard further spoilage, and then sell the blended products to pet food companies.

These fats are sprayed directly onto dried kibble or extruded pellets to make an otherwise bland or distasteful product palatable. The fat also acts as a binding agent to which manufacturers add other flavor enhancers as well. Pet food scientists have discovered that animals love the taste of these sprayed fats. Manufacturers are masters at getting a dog or a cat to eat something she would normally turn up her nose at.

Wheat, Soy, Corn, Peanut Hulls, and Other Vegetable Protein

The amount of grain products used in pet food has risen over the last decade. Once considered filler by the pet food industry, grain products now make up a considerable portion of pet food. The availability of nutrients in grain products is dependent upon the digestibility of the grain. The amount and type of carbohydrate in pet food determines the amount of nutrient value the animal actually gets. Dogs and cats can almost completely absorb carbohydrates from some grains, such as white rice. Up to 20% of other grains can escape digestion. The availability of nutrients for wheat, beans, and oats is poor. The nutrients in potatoes and corn are far less available than those in rice. Carbohydrate that escapes digestion is of little nutritional value due to bacteria in the colon that ferment carbohydrates. Some ingredients, such as peanut hulls, are used strictly for "filler" and have no nutritional value at all!

Two of the top three ingredients in pet food are almost always some form of grain products. Pedigree Performance Food for Dogs lists Ground Corn, Chicken By-Product Meal, and Corn Gluten Meal as its top three ingredients. 9 Lives Crunchy Meals for cats lists Ground Yellow corn, Corn Gluten Meal, and Poultry By-Product Meal as its first three ingredients.  

Since cats are true carnivores -- they must eat meat to fulfill certain physiological needs -- one may wonder why we are feeding a corn-based product to them. The answer is that corn is much cheaper than meat.

Of the top four ingredients of Purina O.N.E. Dog Formula -- Chicken, Ground Yellow Corn, Ground Wheat, and Corn Gluten Meal -- two are corn-based products ... the same product. This industry practice is known as splitting. When components of the same whole ingredients are listed separately -- such as Ground Yellow Corn and Corn Gluten Meal -- it appears there is less corn than chicken, even though the combined weight of the corn ingredients outweigh the chicken.

In 1995 Nature's Recipe pulled thousands of tons of dog food off the shelf after consumers complained that their dogs were vomiting and losing their appetite. Nature's Recipe's loss amounted to $20 million. The problem was a fungus that produced vomitoxin, an aflatoxin, which is a subset of mycotoxin, a poison given off by mold contaminated the wheat.

Although it caused many dogs to vomit, stop eating and have diarrhea, vomitoxin is a milder toxin than most. The more virulent strains of mycotoxins can cause weight loss, liver damage, lameness, and even death. The Nature's Recipe incident prompted the Food and Drug Administration (FDA) to intervene. Dina Butcher, Agriculture Policy Advisor for North Dakota Governor Ed Schafer, concluded that the discovery of vomitoxin in Nature's Recipe wasn't much of a threat to the human population because "the grain that would go into pet food is not a high quality grain. Which means that the grain used in pet food is not fit for human consumption and therefore not a threat to the human population.

Soy is another common ingredient that is sometimes used as filler in pet food. Manufacturers use it to add bulk so that when an animal eats a product containing soy he will feel more sated. While soy has been linked to gas in some dogs, other dogs do quite well with it. Vegetarian dog foods use soy as a protein source.

Industry critics note that many of the ingredients used as humectants -- ingredients such as corn syrup and corn gluten meal which bind water to prevent oxidation -- also bind the water in such a way that the food actually sticks to the colon and may cause blockage. The blockage of the colon may cause an increased risk of cancer of the colon or rectum.

Additives and Preservatives

Many additives are added to commercial pet foods to improve the stability or appearance of the food. Additives provide no nutritional value. Additives include emulsifiers to prevent water and fat from separating. Antioxidants prevent fat from turning rancid and antimicrobials reduce spoilage. Added color and flavor make the product more attractive to consumers and their companion animals.

How prevalent are synthetic additives in pet food? Two-thirds of the pet food manufactured in the United States contains preservatives added by the manufacturer. Of the remaining third, 90% includes ingredients already stabilized by synthetic preservatives. Premixed vitamin additives used to supplement pet food can also contain preservatives. This means that your companion animal may eat food with several types of preservatives that have been added at the rendering plant, the manufacturing plant and in the supplemental vitamins.

Additives in Processed Pet Foods

Anti-caking agents, Lubricants, Antimicrobial agents, Non-nutritive sweeteners, Antioxidants, Nutritive sweeteners, Coloring agents,
Oxidizing and reducing agents, Curing agents, pH control agents,
Drying agents, Processing aids, Emulsifiers, Sequestrants, Firming agents, Solvents/vehicles, Flavor enhancers, Stabilizers, thickeners
Flavoring agents, Surface active agents, Flour treating agents, Surface finishing agents, Formulation aids, Synergists, Humectants
Texturizers, Leavening agents.

Adding chemicals to food originated thousands of years ago with spices, natural preservatives and ripening agents. In the last 40 years, however, the number of food additives has greatly increased. Of the more than 8,600 recognized food additives today, no toxicity information is available for 46% of them. Cancer-causing agents are sometimes permitted if they are used at low enough levels. The risk of continued use at these cancer-causing agents has not been studied and the build up of these agents may be harmful. Ethoxyquin (EQ), for example, was found in dogs' livers and tissues months after it had been removed from their diet, and as of July 31, 1997, the FDA's Center for Veterinary Medicine requested that manufacturers reduce the maximum level for EQ be cut in half, to 75 parts per million.

While the law requires studies of direct toxicity of these additives and preservatives, most of these additives have not been tested for their effect on each other once ingested. Three commonly used preservatives, BHA, BHT, and EQ, have a proven synergistic effect that may lead to the development of certain types of cancer.

Butylated hydroxyanisole (BHA) and butylated hydroxtoluene (BHT) are the most commonly used antioxidants in processed food for human consumption. For these antioxidants, there is little information documenting their toxicity or the safety of long-term use in pet food.

In animal feeds, the most commonly used antioxidant preservative is ethoxyquin. While some pet food critics and veterinarians claim ethoxyquin is a major cause of disease, skin problems, and infertility in dogs, others claim it is the safest, most stable preservative available for pet food. Ethoxyquin is not approved for use as a preservative in human food, however.

Nitrate is the exception to the rule when it comes to safety. Nitrate is used in meat for human consumption. When nitrate combines with bacteria, the chemical can change to another form with carcinogenic properties called nitrosamines. Very small amounts of this chemical can cause acute and chronic liver damage.

"Natural preservatives" and antioxidants are known as Vitamin C, Vitamin E, and mixed tocopherols. While the avoidance of using pet food laced with chemical preservatives is something to consider, some critics think that natural preservatives are somewhat less effective than chemical preservatives.

The Manufacturing Process - How Pet Food Is Made  
Although feed trials are no longer required for a food to meet nutritional standards and profiles, most manufacturers do require a palatability study when developing a new pet food. Animals are fed side by side, one animal fed a new food while the other is fed a similar formula. The total volume eaten is used as a gauge for the palatability of the food. Most pet food companies keep their own animals for taste testing.

Dry food is made with a machine called an expander. First, raw materials are blended, sometimes by hand, other times by computer, in accordance with a recipe developed by nutritionists. The mixture is fed into an expander and steam or hot water is added into the mixture. The mixture is subjected to steam, pressure, and heat until the temperature reaches 305 degrees F. The mixture is then extruded through dies that determine the shape of the final product. Then it is cooked at a high temperatures and high pressure. Then the food is allowed to dry for another 30-45 minutes. Once the food is dried it is usually sprayed with fat to make it more palatable. Although the cooking process may kill bacteria in pet food, the final product can lose its sterility, during the subsequent drying, fat coating, and packaging process.

Ingredients are the same for wet and dry foods. The main difference between the two types of food is the water content. Wet or canned food begins with ground ingredients mixed with additives. If chunks are required, a special extruder forms them. Then the mixture is cooked and canned. The sealed cans are then put into containers resembling pressure cookers and commercial sterilization takes place. Some manufacturers cook the food right in the can.

There are three primary types of wet food. The "all meat" product is defined by AAFCO as "When an ingredient or a combination of ingredients derived from animals, poultry, or fish constitute 95% or more of the total weight of all ingredients of a pet food, the name or names of such ingredient(s) may form part of the product name of the pet food; provided that where more than one ingredient is part of such product name, then all such ingredient names shall be in the same size, style, and color print. For the purpose of this provision, water sufficient for processing shall be excluded when calculating the percentage of the named ingredient(s). However, such named ingredient(s) shall constitute at least 70% of the total product.

The "dinner" product is defined as "When an ingredient or a combination of ingredients constitutes at least 25% but less than 95% of the total weight of all ingredients of a dog or cat food mixture, the name or names of such ingredient or ingredients may form a part of the product name of the pet food if each of the ingredients constitute at least 3% of the product weight excluding water used for processing and only if the product name also includes a primary descriptive term such as 'dinner', 'platter', or similar designation so that the product name describes the contents of the product in accordance with an established law, custom or usage or so that the product name is not misleading. If the names of more than one ingredient are shown, they shall appear in the order of their respective predominance by weight in the product. All such ingredient names and the primary descriptive term shall be in the same size, style and color print. For the purpose of this provision,
water sufficient for processing shall be excluded when calculating the percentage of the named ingredient(s). However, such named ingredient(s) shall constitute at least 10% of the total product.

The "flavor" product is formulated to have a specific flavor, and it is defined as "No flavor designation shall be used on a pet food label unless the flavor is detected by a recognized test method, or is one the presence of which provides a characterisitic distinguishable by the pet. Any flavor designation on a pet food label must either conform to the name of its source as shown in the ingredient statement or the ingredient statement shall show the source of the flavor. The word flavor shall be printed in the same size type and with an equal degree of conspicuousness as the ingredient term(s) from which the flavor designation is derived. Distributors of pet food employing such flavor designation or claims on the labels of the product distributed by them shall, upon request, supply verification of the designated or claimed flavor to the appropriate control official.

What Happened to the Nutrients?

R. L. Wysong, veterinarian and long time critic of the pet food industry, has said, "Processing is the wild card in nutritional value that is, by and large, simply ignored. Heating, freezing, dehydrating, canning, extruding, pelleting, baking, and so forth, are so commonplace that they are simply thought of as synonymous with food itself. The processing practices for grain and meat used in pet food severely diminishes its nutritional value.

To make pet food nutritious, pet food manufacturers must "fortify" it with vitamins and minerals. Why? Because the ingredients they are using are not wholesome, and the harsh manufacturing practices destroy what little nutritional value the food had to begin with.

Contaminants

Commercially manufactured or rendered meat meals are highly contaminated with bacteria because their source is not always slaughtered animals. Animals that have died because of disease, injury, or natural causes are a source of meat for meat meal. The dead animal may not be rendered or cooked until days after its death. Therefore the carcass is often contaminated with bacteria -- Salmonella bacteria contaminate 25-50% of meat meals. While the cooking process may kill bacteria, it does not eliminate the endotoxins that result from the bacteria. These toxins can cause disease. Pet food manufacturers do not test their products for endotoxins.

Escherichia coli (E Coli) is another bacteria that can be found in contaminated pet foods. E Coli bacteria, like Salmonella, can be destroyed by cooking at high temperatures, however, the endotoxin produced by the bacteria will remain. This endotoxin can cause disease as well.

Aflatoxin -- This is a toxin that comes from mold or fungi, as in the case of Nature's Recipe. The improper drying and storage of crops is the cause of mold growth, which can result in Aflatoxin contamination. Ingredients that are most likely to be contaminated with this toxin are cottonseed meal, peanut meal, and fish meal.

Labeling

The National Research Council (NRC) of the Academy of Sciences set the nutritional standards for pet food until 1974, when the pet food industry created a group called the American Association of Feed Control Officials (AAFCO). At that time AAFCO chose to adopt the NRC standards rather than develop its own. The NRC standards required feeding trials for pet foods that claimed to be "complete" and "balanced." The pet food industry found the feeding trials to be too restrictive, so AAFCO designed an alternate procedure for claiming the nutritional adequacy of pet food. Instead of feeding trials, chemical analysis would be done to determine if a food met or exceeded the NRC standards.

The problem with chemical analysis is that it does not address the palatability, digestibility and biological availability of nutrients in pet food. Thus it is unreliable for determining whether a food will provide an animal with sufficient nutrients.

To compensate for the limitations of chemical analysis, AAFCO added a "safety factor," which was to exceed the minimum amount of nutrients required to meet the complete and balanced requirements. By establishing its own standards and disregarding the NRC standards, AAFCO established itself as the governing body for pet food. In essence the pet food industry developed their own standards for nutritional adequacy.

The 100% Myth -- Problems Caused by Inadequate Nutrition

The idea of one pet food providing all the nutrition a companion animal will ever need for its entire life is a myth... Cereals are the primary ingredients in most commercial pet foods. Most people select one pet food and feed it to their dogs and cats for a prolonged period of time. Therefore companion dogs and cats eat a primarily carbohydrate diet with little variety. Today, the diets of cats and dogs are a far cry from the primarily protein diets with a lot of variety that their ancestors ate. The problems associated with a commercial diet are seen every day at veterinary establishments. Chronic digestive problems, such as chronic diarrhea, are among the most frequent illnesses treated.

Allergy or hypersensitivity to foods is a common problem usually seen as diarrhea or vomiting. Food allergies have become an everyday ailment. The market for "limited antigen" also known as "hypoallergenic" diets is now a multi-million dollar business. These diets were formulated to address the increasing intolerance to foods that animals have developed.

Many commercial pet foods are made with ingredients that have poor protein digestibility. Diets containing protein with less than 70% digestibility cause diarrhea in dogs. Some fillers used in these foods can also cause colitis, which is the inflammation of the colon. Most pet food companies do not publish digestibility statistics and they are never seen on pet food labels.

Acute vomiting and diarrhea is often a symptom of bacteria contamination and the toxins bacteria produce. Dry commercial pet food is often contaminated with bacteris, which may or may not cause problems. Improper food storage and some feeding practices may result in the multiplication of this bacteria. For example, adding water to moisten pet food and then leaving it at room temperature causes bacteria to multiply. Yet this practice is suggested on the back of some kitten and puppy foods.

Pet food formulas and the practice of feeding that manufacturers recommend have increased other digestive problems. Feeding only one meal per day can cause the irritation of the esophagus by stomach acid. Feeding two smaller meals is better.

Urinary tract disease is directly related to diet in both cats and dogs. Plugs, crystals, and stones in cat bladders are caused by commercial pet food formulas. One type of stone found in cats is less common now, but another more dangerous type has become more common. Manipulation of manufactured cat food formulas to affect acidity in urine and the amount of some minerals has directly affected these diseases. Dogs also form stones as a result of their diet.

History has shown that commercial pet food products can cause disease. An often-fatal heart disease in cats and some dogs was shown to be caused by a deficiency of an amino acid called taurine. Blindness is another symptom of taurine deficiency. This deficiency occurred because of inadequate amounts of taurine in cat food formulas. Cat foods are now supplemented with taurine.

Rapid growth in large breed puppies has been shown to contribute to bone and joint disease. Excess calories in manufactured puppy food formulas promote rapid growth. There are now special puppy foods for large breed dogs. But this recent change will not help the countless dogs who lived and died with hip and elbow disease.

There is also evidence that hyperthyroidism in cats results from commercial pet food diets. This is a new disease that first surfaced in the 1970s, when canned food products appeared on the market. The exact cause and effect are not yet known. This is a serious and sometimes terminal disease and treatment is expensive.

Many nutritional problems appeared with the popularity of cereal-based commercial pet foods. Some occur because the diet is incomplete. Some are a result of additives. Others are a result of contamination with bacteria, toxins and other organisms. In some diseases the role of commercial pet food is understood, in others, it is not. The bottom line is that diets composed primarily of low quality cereals and rendered meat meals are not as nutritious or safe as you should expect for your cat or dog.

Despite the appealing blandishments of pet food advertisements with their claims of providing "complete and balanced nutrition," if you're not exceedingly circumspect, you may end up feeding your pet chicken heads, road kills, spoiled or moldy grains, cancerous material cut from slaughterhouse animals, tissue high in hormone or pesticide residues, and even shredded Styrofoam packaging, metal ID tags and minced flea collars.  

A growing number of veterinarians state that processed pet food (kibbles and canned food) is the main cause of illness and premature death in the modern dog and cat. In December 1995, the British Journal of Small Animal Practice published a paper contending that processed pet food supresses the immune system and leads to liver, kidney, heart and other diseases. Dr. Kollath, of the Karolinska Hospital in Stockholm, headed a study done on animals. When young animals were fed cooked and processed foods they initially appeared to be healthy. However, as the animals reached adulthood, they began to age more quickly than normal and also developed chronic degenerative disease symptoms. A control group of animals raised on raw foods aged less quickly and were free of degenerative disease.  

The pet nutrition industry is a multi-billion dollar industry full of hype and false claims. Consumers are being duped into believing that they are feeding their pets healthy foods, when in actuality they are feeding nothing more than inferior meat meals, cheap grains (including corn and soy), fillers, by-products, pesticides, preservatives and toxins.  Never before has the pet-food industry been rocked by widespread contamination and rampant recalls. In all, more than 5,600 products by dozens of pet food makers have been recalled, from chain supermarket brands to prescription-only foods. This is a staggering number of products, and is unprecedented in this business. Thousands of deaths are due to the contamination, and many thousands more have suffered illnesses. We shudder to think of the long-term impacts of the compromised liver and kidney function and how this will affect thousands of companion animals in America. Leading experts believe that the severe reactions experienced by some cats and dogs were the result of an interaction of chemicals, between the melamine and a list of other culprits, including cyuranic acid.  Read the latest about the pet food recall. Thousands of Cats and dogs suffered kidney failure, and many died after eating the affected pet food.  

Dr. Don E. Lundholm, D.V.M. - "We are seeing disease conditions in animals that we did not see years ago. Many of these may be traced to nutrition as the source..."

The primary ingredient in many dry commercial pet foods is not protein but cereal. Corn and wheat are the most common grains used but, as with the meat sources, the nutritious parts of the grain are generally present only in trace amounts. The corn gluten meal or wheat middlings added to pet foods are the leftovers after the grain has been processed for human use, containing little nutritional value. Or they may be grain that is too moldy for humans to eat, so it's incorporated into pet food.

Mycotoxins, potentially deadly fungal toxins that multiply in moldy grains, have been found in pet foods in recent years. In 1995, Nature's Recipe recalled tons of their dog food after dogs became ill from eating it. The food was found to contain vomitoxin, a mycotoxin. Harmful chemicals and preservatives are added to both wet and dry food. For example, sodium nitrite, a coloring agent and preservative and potential carcinogen, is a common additive. Other preservatives include ethoxyquin (an insecticide that has been linked to liver cancer) and BHA and BHT, chemicals also suspected of causing cancer. The average dog can consume as much as 26 pounds of preservatives every year from eating commercial dog foods.

Hopefully the information I've sent your way will help to offer some insight into your kitten's nutritional needs and the best ways to meet them. I suspect that feeding your cat a homemade raw diet or a commercially produced high quality, holistic cat food made with human grade ingredients will put an end to him being quite so picky about his food and a higher quality diet will probably help to stop the vomiting. If a change in diet doesn't help to stop or reduce the frequency of the vomiting it's probably a good idea consult either your regular family vet or a holistic veterinarian in your area. A holistic vet is simply a vet trained in conventional medicine as well as one or more alternative therapies including homeopathy, acupuncture or massage to name a few. My family vet is a wonderful holistic vet and I've seen some pretty incredible results when appropriate homeopathic remedies are given.

For some cats vomiting can happen more frequently than if the cat is sensitive to furballs. You can help remedy the hairball situation by providing your cat with about a tablespoon of canned pumpkin (not pumpkin pie mix, pure pumpkin) a day, this provides a bit of extra fiber to help move things through your cat's system more efficiently. If you choose to offer canned pumpkin to your cat it's a good idea to freeze the puree in ice cube trays which provide a convenient portion sized cube once frozen because the canned pumpkin has a tendency to grow mold if kept in the fridge over a long period of time. Some cats don't like canned pumpkin, you could offer commercially available hairball remedies or a small amount of butter or margarine. Failing that having cat grass in your home will provide some extra fiber that appeals to most cats, you can also try your cat on small amounts of steamed broccoli or carrots, cooked squash or even raw baby spinach to see what he enjoys. Cats are carnivores by nature, the reason that I recommend adding a small amount of steamed vegetables or raw leafy greens to their diet is because they would actually eat the stomach and digestive tract of prey animals if they were relying on hunting as a means of survival and these prey animals would have small amounts of pre-digested vegetable matter in their stomach and digestive tracts.

Expertise

I am the proud guardian of 5 mixed breed cats ranging from 12 weeks to 13 years old and one purebred ragdoll. I have 20+ years experience working with mixed breed cats from a variety of different situations. I have fostered cats/kittens with special needs/behavioral issues. I have rescued/rehabilitated/re-homed a variety of stray/abused cats. I can offer advice on managing feral cat colonies, rehabilitating strays and finding them forever homes. I can help you to determine whether a cat is stray or feral, there IS a significant difference. Improperly introducing a new cat/kitten can result in aggression between newly introduced cats because cats are territorial by nature and they don't like sudden changes in their environment. To learn more about a peaceful way to introduce a new cat into a home with other cats please check out my previous answers on this subject. Proper nutrition for cats can be confusing, I recommend checking out catinfo.org which was created by a veterinarian (Dr. Lisa Pierson) who takes a common sense approach to explaining feline nutrition. Cat behavior and instincts are different from those of humans, I can help you understand your cat's needs so that you can meet them adequately and have a balanced, psychologically and physically sound kitty. Cats vary in personality, energy level and intelligence, different approaches may be required to achieve results in terms of training and interaction with your feline companion. An intelligent, high energy cat must be kept busy or they will make their own fun. I am NOT a licensed veterinarian and I can't offer medical advice. If your cat is ill/injured my advice is always the same: get prompt medical treatment provided by a veterinarian. If finances are an issue I will try to find resources in your area that can help with medical costs or make other choices to ensure the welfare of your cat.

Experience

I have fostered feral and stray cats, rehabilitated and homed cats that many people recommended euthanasia for. I am willing to make an effort to do the research and ask questions because I care enough to find solutions to behavioral problems rather than giving up. I have an interest in the use of alternative therapies to help provide the best possible care for all cats and I can say in all honesty that I've seen some incredible things happen for some incredible cats and their human caregivers when the right alternative therapeutic modality is used by a qualified veterinarian with expertise and experience in the field.
