Cat Food/Alternatives to Prescription Diet C/D for cats?

I understand completely your concern and problem.

Heres my experience.  I too adopted a cat who had urinary tract problems and nearly died from it.  After 3 days hospitalization and a 300 dollar vet bill his diet was switched to hills prescription diet c/d.  I followed his special diet consistently for several years and never had any problems.  But about a year ago I got overconfident and tired of running to the vet for food and paying the more expensive price.  So I switched to a common name brand cat foods indoor formula.  Things were fine for a while but then he stared to get sick again and we have been back to the vet twice in the past 3 months.  Both overnight stays and more expense.

His diet has been switched back to the hills prescription diet and his condition is slowly improving although my cat still has periods of painful and bloody urine and occasionally has to be given muscle relaxers.  I truly wish I had never changed his diet and I would advise you to think twice about going against your vets advice.

I had a similar experience.  And a $1200 vet bill.  I would love to switch from the c/d diet, but last time I did that (going to a holistic dry feed from Trader Joe's) - boom - blocked urinary tract and 2 overnight stays at the vet's.

I can see hydrating the cat helps, but cats have very different chemistry than other animals.  My cat drinks quite a bit, but still, the c/d is the only thing that has consistently worked in 4 years (he is an otherwise very healthy 11+ year-old.)

I might be willing to take another financial hit to see if something else works, but if it doesn't, I'm not sure my cat can keep going through the stress of a blocked urinary tract.

Good luck everyone, and thanks for giving homes to cats!

You are absolutely right to be skeptical. I have a had a very similiar experience. My cat has had problems with urethral blockage and crystal formations in his bladder. I was told that Prescription Diet was my only/best choice. After paying a hefty bill to have his urethral blockage removed, I began feeding the Hill's food. He still had the same problems a few weeks later! I did some independent research and realized that the reasons are numerous, but it seems the best prevention is feeding a wet food diet. Ideally, you should feed a raw diet. But I'm not even willing to by my cat cuts of steak, so I've switched to Innova Evo canned food that is 95% meat. My cat has had no problems since! The first ingredient in the prescription diet is a grain anyway! Cats or Horses are not cows, they should be eating meat, not grains. I'm kind of outraged that this was not made more clear to me by my vet.

Good luck! :)

This answer is not accurate.   Some cats do need to be on prescription diets.  My female cat has FLUTD, struvite crystals.  The only thing that keeps her urine clear is Hills prescription c/d.  And yes I have tried a high quality, non prescription all canned diet. Raw is not the answer, either.

In the case of a male it is even more important as males block easily.  Going off a prescription diet could be fatal for a male cat, and it is not a pleasant death.

Vets are not paid to sell Hills prescription foods.  They carry them as a convenience to their clients.  They make very little, if any money from these foods.

Prescription foods are made the way they are for a reason.  They are not for normal healthy cats. It is irresponsible to advise someone to not use a prescription diet if a vet has recommended it.

We had a similar experience.  Our male cat nearly died due to a urinary block...the first vet mis-diagnosed it and after a night in the "kitty emergency room", my wife in tears, and around $1,000 of vet bills our cat had his bladder flushed and the vet put him on "wet" cat food once a day and the C/D diet.  It has been about four years now and he hasn't had any more problems.  Yes, it isn't cheap, but neither are over night vet stays.  AL, Virginia

Cats do eat mainly raw meat in the wild, and they usually live no longer than TEN YEARS.  It is very rate ti find a serval cat, civet, lion, tiger or any other wild cat alive after its tenth birthday.  You are running a big risk with your pet's health to disregard the advice of your vet.  Besides Hills c/d feline canned food there is c/d dry food and Royal Canin SO pouches and dry food.  I have found that 12 x 156g cans of Hills Feline C/D is the best bargain price-wise.

When I told my vet that the Royal Canin SO pouches they carry are too expensive, she actually suggested I try the Hills c/d cans online - for which the vet would get no benefit at all.

I wish it only cost $1,000 when my cat was blocked. I now have $3,000 "alley cat" after my cat spent about 5-6 days at the vet.  It's only been 2.5 months on C/D, but cat's had 2 urinary test, and so far so good.  Not worth the risk of trying alternative.  By the way.. the Vet that has put my cat on the diet, is not the vet that got the majority of the $3k...

Rich wrote at 2010-09-19 14:19:13
I suspect the reality is a balance.

If your cat has urinary problems, he does need a carefully controlled diet.  If you go out and just buy any old cat food it is likely that they will have serious problems.

The Hill's c/d food will often solve the problem - it certainly has in our case.

However, I'm not convinced that something else (likely far cheaper) wouldn't work just as well.  I can't vouch for any of the alternatives, but I think that dismissing them all outright isn't good advice.  

In our case we're sticking with the c/d since our cat has been established on it for a while and we know it works.  We don't really want to mess around with the cat's health, and there isn't even any financial savings if he ends up in the vet overnight.

What I really dislike about the situation, however, is that the food can only be bought from a vet.  That is a MAJOR conflict of interest and this practice should really be illegal.  People love to bash pharmaceutical companies for their sales tactics, but even they aren't this brazen (at least not with pills for humans).

I'm sorry - I just can't accept the advice of my vet at face value when they have a financial stake in the advice they are giving.  That doesn't make them wrong, but you are certainly not foolish to question them.  That said, our cat has done very well on this food for years, so I can't knock it either.

Hey Nodeclaw,

The expert answer provided is based on FACT -- NOT what Tv advertisements and vets with a conflict of interest are selling people.

FACT:  Cats are the strictest of all  carnivorous mammals

FACT: Cats teeth do NOT rotate; NOR do they have teeth designed to grind.

Care to dispute these facts?  

Just because DEHYDRATED cats are forced to consume more WATER while on these diets, does not make this "food" the solution -- all it does is dent your bank account and dehydrate your cat enough to head for the water bowl more often than is NATURAL for the species.

But don't believe me, or the UNBIASED expert resources provided --

Urinary blockages should be taken very seriously. Some of you have had high vet bills and high food bills, and I understand how that pinches. But I just spent over $10,000 (yes, I typed that correctly) keeping my cat alive. The most horrible part of it was, ultimately, he had to be euthanized. He had the best care available to him in Los Angeles, and he was a big, beautiful, healthy cat. But this problem brought on complications that just threw him for a loop, and after two weeks in and out of hospitals, his body couldn't recover. My advice is feed your pet what your vet prescribes (who cares if he makes money from it? Everyone has to make a living and vets are not millionaires.) Also, look out for the warning signs. I regret to this day that I might have noticed his problem too late.

One more thing -- get an x-ray. My sweet baby's problem was diagnosed the first time as struvite crystals, but when he got worse, an x-ray revealed stones.

jbreezy wrote at 2011-03-30 14:38:54
I too, have a cat with crystal issues and don't like the idea of feeding science diet - since it seems to be filled with junk.  However, my cat was on wellness wet food her whole life until getting this problem.  In case you aren't aware, wellness is all protein and of course wet - the so called perfect natural cat diet!  Since she has been on hills C/D - no more UTI problems... What can I say?  The wonderful high protein diet was actually CAUSING the problem!   P.S. I still give her a small amount of wet food (paul newmans with grain) as a supplement so she doesn't dry out.

I too have recently took my cat "Oscar" to the vet for urinary tract blockage,spent 4 days there, costing over $500.00 dollars. They put him on the c/d diet and is doing well now. We recommend that you stick too the vet advice so you cat can live a long and happy life. Thank you for loving your pet.:)

I appreciate this thread, and wanted to add my two cents. I have a female Manx who is prone to urinary problems when stressed. After trying a variety of prescription diets (my vet sent home a sample pack to see what she preferred) we settled on wet c/d. After trying it off and on (with recurrent urinary problems when she was off), I am committed to keeping her on it. I am convinced that for my cat, staying on it keeps her more comfortable and problem-free. I HATE the way it smells, it is an inconvenience to purchase at the vet, and a painful change from feeding two cats the same kibble (my other cat, a Maine Coon on Wellness dry, wants her wet food so desperately!), but it works for us.

My poor little baby has struvite crystals and i was told to give him hills s/d he hates it, the smell and the taste the wet food i can only get him to eat if if i mix it with water and then he only sucks all the water out and leaves the meat behind so i've just gone and brought the royal canin so to see if that works, im hoping it does its expensive and a bit of pain as i dont drive so its hard to get to the vets to buy it but its all worth it if he will eat it. fingers crossed he likes this new one

I have a 9 year old fixed male who had a urinary problem 5 years ago and has been on C/D dry and wet since with no problems.  He supplements with birds, eating everything but feathers.  I add lots of water to the wet and he eats 90% of it all and sometimes all.  I did cut the wet to once a day and then only 1 rounded tablespoon.  The dry is out all the time and he eats a lot of it.  I seldom see him drink water. Good luck to all with your kitties.

My cat is 13 years old. She has been on Hills c/d formula for over 8 years. She hates it, she eats it because I do not give her other options but I can tell she dislikes it. I've fed her the dry & wet food can (seafood/ chicken) over all these years and never had anymore problems with her urinary track. However; she just don't care for it anymore and last year I started to give her Pro Plan Nestle Purina Canned food for Urinary Tract for Cats once per week.  I continue to give her Hills c/d dry in the morning and at night I will switch between the wet cd/ and the Purina pro plan.  I just started buying it to add a little variety but I do not stop giving her Hills c/d . I wish Hills c/d came in different flavors besides the chicken/ seafood.

I just dropped 2555.93 on a 3 night stay for my recently 1 year old cat. He's in great shape, his coat is flawless and I have been paying $50 a month on 30lbs of salmon and indoor kibbles from Blue Buffalo. I had him on the high protein Wilderness diet. His urethra was extremely blocked, he was loaded with crystals and his kidney values were sky high. He had a fair quantity of blood in his urine and had a slight fever. He was lucky that I noticed it quickly, because he probably would have been dead before the weekend. (He was admitted on Monday). They want to put him on the Royal Canin SO. I've heard of the recent contamination of Royal Canin food causing diarrhea and vomiting and a side effect of the food is extreme weight gain.

I have every intention of sticking to the diet that my vet is prescribing, but Lebowski doesn't like it. (The dude is not abiding) So is the Hills comparable to the Royal Canin?

My 5 year old cat Felix had major urinary problems ie struvites and bloody urine, the works! He had 2 relapses already and the 2nd one was due to the fact that I stopped giving him the Hills CD wet formula. I had switched him to the dry formula at the time, thinking it will help avoid any unwanted dental problems but unfortunately his urinary problems have returned full force and we had to have him hospitalized for a few days. A few thousand dollars later, we decided to keep him on the CD wet formula and he's been going great ever since. We feed him a can a day, half in the morning and other half in the afternoon. We add water to it and tuna dry tuna flakes and he loves it. At the beginning he refused to eat it (he's a finicky eater too!) but now he eats it and he hasn't had any health problems for the past 2 years and counting. I hope to be able to enjoy his lovely company for at least 15 more years!!! :))

It seems to me that cats do eat grain and grass in the wild--the stuff that is found in prey animals' intestines. (I believe this is the first thing they go after once the animal is caught.) If someone would care to comment on this, I would be interested in hearing it.

You can get the Hill's Prescription Diet c/d food online. I plan to purchase it from Pet360. They also have the s/d version, as well as several other versions with which I'm not familiar. I called today, as my cat was just diagnosed with struvite crystals (I got my first batch of food from the vet), and was told that when I order, I just need to give them the vet's name and phone number, and they will call to verify. Check it out!

Hi all

I have a female who is nine years old. A few years ago she developed a UTI and was put on the Royal Canin SO. I kept her on it for a year, tried to take her off, and she developed another UTI. However, I have found out that the Royal Canin SO is not recommended for long term use. It is sorely missing in the overall nutrition department (according to my vet) and can actually cause serious problems when used long term with the cat's blood work (mainly the electrolytes) which can actually lead to death! Since finding this out, she has recently been switched to the Hill's C/D which is made for long term use. She seems to love the food and we will see how it works for her.

I too have had HIGH vet bills from urinary problems mainly struvite crystals and ended up having to put my cat on hills c/d. I hate the ingredients of the prescription food (i used to feed him the really awesome natural foods) but I love my cat and the food really helped him avoid surgery. I would like to tell everyone about a supplement that is available at natural health stores (for humans) called D-Mannose, its used to help women's urinary issues but its 100% safe to sprinkle the powder on your cat/dogs food. It is amazing!!! When I combined the prescription food and the d-mannose, ALL of the crystals ( and there were a lot of crystals) were gone within a week or 2 and he was feeling better in a few days. I guess the d-mannose is a type of sugar that attracts the bad bacteria in the bladder and helps flush it out more efficiently and less painfully. And I don't know about anyone else, but my little cat/trouble maker didn't want to eat the prescription food at first but the d-mannose is a little sweet and my cat gobbled it up like thanksgiving! I hope this little tidbit will help you out, good luck everyone taking care of your loved ones!!

Hello cat also has had UTI problems and the doctor prescribed cd for him. He ate it for a while, and not being aware I tried to switch him to non-prescription Wellness and other grain free cat foods, and the problem came back. I will keep him on cd from now on...I never want him to go through that again.

The problem that I find with the food is that it's prescription...why does a vet need to keep writing a scrip for me to purchase it?  That I don't understand...

My little Siamese girl is of a breed prone to crystals, she had surgery at age 6 for calcium oxalate crystals which has now become more common than the struvite around here. The only recourse is surgery for calcium oxalate crystals once they form large stones that will not pass - so there is no "experimenting" on changing back to a different diet without grave consequences. After her surgery in '09 they put her on Royal Canin's CD variety, and it was strongly suggested to us to use distilled water to avoid additional minerals that could be in our well water. After 2 months her urine test showed small crystals being passed. My vet researched the other varieties of food available and found that Hills CD had the lowest percent of calcium. So we switched, however, the problem persisted. Then, on a hunch we pH tested the distilled water. Calcium oxalate crystals will form in a more acidic pH, and I think struvite requires a more basic pH. Most CD foods hover around neutral in an attempt to be useful for both conditions. Every jug of distilled water I tested was a pH hovering around 5.0 to 5.5. Thankfully the fix was easy (I'm married to a chemist), we now correct the pH of the distilled water to 7. Four years later and we stopped bothering to test her urine, have had no signs of trouble since.

In 1986, I returned home from work one night to find my cat was in severe pain, he was constantly licking his bottom repeatedly and crying, so we took him to the vet immediately.  My orange 2 year old male cat, AJ, suffered from urinary bladder crystals and had emergency surgery to remove the urethral blockage that night.  (My Vet said if I had waited much longer, or by morning, he probably would not have made it.)  I paid about $800 back in 1986 for his treatment and my Vet recommended the Hillís CD Prescription diet at that time.  It took my cat a few days to get used to the new (dry) CD Prescription food but he accepted it and later really loved it!  His coat was beautiful and he appeared to be very happy, content and healthy.  AJ went on and lived to be 19 years old, eating the Hillís CD Prescription (dry) diet for 17 years, without further incident.  In his later senior years I did add CD (wet) canned food twice a week as a treat.  Yes, at times it was inconvenient to purchase his food at my Vets office and in later years found I could also get it at Pet Smart, too.  However, I would not change a thing, since AJ did so well.  Also, my two current male cats, who are 13 and 8 years old, have been on the regular Hillís Science Diet.  We use the Indoor and I alternate the Hairball and Oral care products in a second feeder to add some variety.  I also split a wet can of  regular SD food in the evening, as a treat only, and appear to be doing well.  I donít know if I want to risk changing their food brand with all the confusing news out there with regard to grain less, natural and raw brands.  I want my cats to have the best and hope that they are getting it since all the marketing ploys can be very frustrating.  So I will continue with my current diet until I have more concrete diet information to the contrary. Best of luck to all!

I have looked into this a lot.  I also spent hundreds on having my cat's bladder stones removed surgically -- and he didn't like it much either!

Cat food for bladder/urinary problems has a low Ph level (6.2-6.4).  Meat is very acidic with a high Ph level, so these cat foods have much less meat in them.  Most common cat foods have a MUCH higher Ph because they have more meat.  

Cats are carnivorous, so it's VERY difficult to offer the right essential nutrients with a low meat/fish content - and have he cat enjoy the taste..  That's why the specialty cat foods like S/O and C/D are expensive.  But, if you buy them online in large bags they are MUCH cheaper than at the vets and often come with free delivery.

If for some reason you need a prescription in the US, ask the vet for a prescription to use online.  In the UK you don't need it.

In fact, my vet told me that cats' bladder problems (like bladder stone and bloody urine like mine did) usually come from the high acid content of modern cat food, dry or wet.  In the wild, big cats usually die by age 10 from bladder and kidney-related problems, solely from eating a high-meat diet all their lives.  

I tried to find foods I could give mine as a treat by searching for the Ph content of foods online - but even cheese, eggs and seafood are very acidic.

For cats (and humans), a lower Ph level is actually MUCH healthier.  

I also now put a quarter teaspoon of baking soda it my cats' water -- it lowers the body's Ph level and also helps prevent plaque in their teeth!

I have an 8 yr old male short hair tabby. I had him since he was 3 mos old. He was neutered and had all his shots. When he was about to turn 1, he got an urinary tract infection. I bought him to the vet and he was given antibiotics and I was told to put him on a prescription formula diet...Hill's C/D formula for bladder infection. My cat has been on this diet has been 7 yrs of him eating the wet and dry formula. At first he didn't like it, but the vet said I could mix it w/Fancy Feast. So I give him some of the wet formula and mix it w/some of the Fancy Feast. My cat loves it and always eats his bowl clean. His second feeding, I give him some of the dry chicken formula and he gobbles that up as well. My point is, this diet works and my cat hasn't had a health issue since. And I bring him to the vet twice a yr for check-ups and blood tests. Since my cat got this illness so young, he's definitely susceptible to it for the rest of his life. And being 8 yrs old, he's already old. My cat was bleeding in his urine badly and I could tell he was in pain. Luckily I caught his illness in time before he developed crystals or stones. I avoided a hefty vet bill as well. It is important to take care of our pets. This diet formula isn't cheap at all and the prices has gone up dramatically in the past few yrs, but if you love your pets and want them to live long and healthy lives...preventive medicine is the best cure. Btw, my cat's vet also recommended I shouldn't feed him too much of the dry food because it will make my cat gain weight. It is true and since I cut back on my cat's dry portion, he has lost weight and is now fit, slender and a healthy weight. And it's true these vets who sell these prescription formulas don't make a lot of money off of it. There's no profit in them selling these foods to us. It only benefits our pets and help prevent future illnesses. I also recommend bringing your pets to the Humane Society...great vets who don't rip you off!

Will wrote at 2013-07-27 01:30:10
Karolina you have absolutely no idea what you are talking about. A low pH is acidic, not basic. You have it completely backwards and are introducing something into your cat's food ( i.e., baking soda) that *neutralizes* acid. Sodium bicarbonate (baking soda) is a common ingredient in OTC stomach antacids because it helps neutralize stomach acid. A lower urine pH is healthy for cats because it is acidic, not basic. Good god. It is frustrating to read a post like yours that is giving completely innaccurate information so authoritatively. You need to quit pretending to be a vet and get a proper education on this matter before you go making people's animals sick. Argh!

(I work in IT - this is an honest testimonial - I'm unrelated to any place I mention.):

 I'm quite happy to see that a thread that's so important in the lives of cats that we all love and care for (I have two Russian Blues, one who is FLUTD, and in addition to the FLUTD kitty going to the 24 hour emergency vet but more or less saved from death by the FABULOUS people at the University of Wisconsin school of Veterinary Medicine, all said about $2,000) - I've consistently been told that for this one kitty, Hill's C/D and S/D for short and long term is really the optimal way to go.

 My other Blue, I feed him food from Fromm, a company that's in my opinion second to none for non-Rx food.  I vary his feeding, he likes every flavor of food, way above and beyond any other (I've tried pretty much every other food, including even Chicken Soup).

 I baby my cats (and no, I'm not a crazy cat person) - and being a nerd, I've researched ingredients, and what percentage of what category seems optimal -- both Hill's Prescription and Fromm have that down pat.  Even down to the pellet size.

 I can't emphasize more that the food you give to your cat really has a significant impact on your cat's life.  If S/he has a need for Prescription food, don't look for cheap alternatives, because there is actually regulation involved when you enter the scripted market.  And there's a reason for that -- It's not so much that it's something that needs to be controlled (like, say, you get a prescription for Vicodin) -- but that it's /Regulated/.

 Final note and plug about Fromm -- They're (from what I can tell) the ONLY pet food manufacturer that has not issued or been involved in a product recall.  EVERY OTHER ONE HAS.

 That risk isn't worth it to me.

 I hope this post helps some people make that decision to treat your animals as you would expect to be treated yourself.

There are alternatives.  I was a vet tech for 10 years. I have taken in many cats that were going to be destroyed due to crystal problems.  I also have several cats with other health issues that would not benefit from the high fat content in c/d. I check regular urine samples and dose cats regularly as appropriate with a urinary acidified called dlm. It comes in pill or chewable format. Really cheap esp if you buy in bulk. Saved many of my cats lives and has kept the rest of the crew healthier off the persecription diet.  I have had no relapses and get to feed a high quality grain free food that nourishes the rest of their body. Also to note those who said the vets don't make a huge profit on the food are full of crap. I used to do ordering and billing. The markup is astounding and they put your pet on it for life! I advise research into urinary acidifiers and talk to your vet.

HI all,

LIke many of you, I too am struggling with a 2 year old male cat with chronic ideopathic feline cystitis. It all started in October 2104 when Finley--a formerly feral rescue--was about a year and 4 months old. He tested positive for a UTI, was given an antibiotic and got better. Symptoms came back in January 2015, took him in for a urinalysis (always do this!) and there was no UTI and no crystals. A  He had an ultrasound as well. Eventually the flare-up subsided. He is toilet trained so I was actually see him struggle while atop the toilet seat and could see blood in his urine so back to the vet he went (thank goodness for pet insurance)a few months later. Nothing again...and he had an ultrasound and all was fine. I started him on Cosequin--an anti-inflammatory--and things calmed down. I got sick of the diet food at some point and put him back on dry food (Purina INdoor formula) but stopped and was exclusively feeding him Trader Joe's more "healthy" canned food. During all this I took him to a holistic vet who advised weekly injections of the anti-inflammatory Adequan and that seemed to work really well...until new Silver Bengal kitten came home! lol Three weeks later, he was straining/producing very little urine and he went back to the vet again. This time he DID have crystals so I started him on the pain meds and HIlls Prescription Diet C/D exclusively. It's been almost a week and his symptoms are gone. I am not crazy about the ingredients in Hills either but, for a cat who has urinary issues, I think it might be the best way to go.

It was great to see all of this info! We have a rescued Manx that was using her litter boxes (we have 2), but was also urinating inappropriately.  Took her to the vet and she tested positive for bacteria. A few days after a 14 day course of antibiotics, same thing.  More testing and cultures showed enterococcus. An xray showed no sign of stones or blockage.  Another 14 day course of antibiotics with NO improvement (this has all cost about $500 total).  Next stop internal medicine vet for an ultrasound and checkup to the tune of $460 (plus the cost of the cosequin).  They found nothing and diagnosed her with FLUTD.  The rescue had no idea how old she was and aged her at around 1 1/2.  After the ultrasound, the internal medicine vet aged her between 4 and 5 based on how her kidneys looked.

She prescribed cosequin and science diet c/d canned.  Been doing this for several days and she seems to be doing well. FINALLY!  I did add UTI Free to her food as well.

Keeping my fingers crossed!!!

My ginger male cat has had urinary crystals problems which began a year ago. We have had one urinary tract blockage(yes expensive & painful), followed by another 'ouch too many crystals' episode around 1 month later. My cats vet put him on Hill's CD wet & dry straight after the blockage.

For the last year - my cat has had a quarter of the Hill's wet can (chicken) 2 X per day - with some Hill's dry biscuits on top of the wet (dry is limited only with wet food meals). He's been going really well with no further bladder problems since, thanks to Hill's C/D doing a great job keeping his bladder working well.

Directly after the 1st blockage event - I did start-out feeding him a bowl of Hills CD dry food (as I used to before the blockage), but those bowls of Hill's CD dry food alone, caused his crystals to start-up again for a 2nd time. After that time - I tweaked it to wet & dry together & on the same plate, with a few teaspoons of rain water each meal - & all has been well in our world for the last year....

Until today... Hill's C/D, & I guess the other Hill's products (Wet food) (don't know about the dry food), have changed their labeling & branding recently. It appears the vet's have been told 'it's just the label that's changed', 'not the formula itself' - So, I take these new can's home, & feed them to my cat as normal & in the same way I fed him the old ones . (My cat has always had a very sensitive gut, even from a kitten - so during his history, & over the years (he's 8-ish now) I've had to try him on different foods to find out which ones he can keep  down & not puke-up).  

The new Hill's C/D has made my cat extremely sick over the last 2 days -  So, today was a big big day at the vets for him & I. It's interesting that although the formula was not supposed to be changed at all - the food looks very different to the old food, on the cat's plate - When water is mixed into it (which I add to his food at feeding-time) the new Hill's wet food has something in it that makes the food look red now :< - Anyways, lucky, my vet has one more tray of the old Hills can's (before the rebranding) that I can feed him before I have to start pulling my hair out - of What the HELL to feed him!!! Royal Caine does not sound like an option from what I've read here - (even though my Vet suggested it as one). I can't feed him only dry , cos that will cause crystals like it did the last time I went 'more dry, than wet' - So, I have 2 issues to deal with, a sensitive gut, & crystals. I have no idea what to do...:/

The person who mentioned this 'Dim' chew-able tablet - This sounds interesting - perhaps it's available Down-Under (which is where I am)

My area of research is in regards to feline diet and digestive physiology as well as history of domestication and how it applies to dietary adaptation in Felis catus.


In total, between my own pet cats and the ones Ive taken in/ re-homed as rescues, I have fed a total of over 95 cats and kittens a natural, raw diet. I have a cumulative of 7 years worth of experience, from feeding a partly prey and partly processed food diet to a completely prey (home bred quail, young home bred chickens, captive bred feeder rodents/ rabbits) and raw meaty bones diet (chicken neck bones and wings), which I currently feed. I have assisted numerous people in formulating a raw diet which is suited for their animals and their lifestyle.

Biology degree with an emphasis in Ag and animal husbandry related courses. I have worked in veterinary medicine and am currently completing my RVT certification. I was accepted into a veterinary medicine program, but due to unforeseen life changes, I am currently unable to begin vet school.
Please consider that I am not a veterinarian, nor do I play on on TV. ;-) I will offer advice to the limit of my own knowledge and when in doubt of my own qualifications to address specific issues, I will refer to you a medical professional who is more suited.

For a good book about carnivore diet, I recommend "Raw Meaty Bones Promote Health," by Dr. Tom Lonsdale DVM
Here are Dr. Londales suggestions for feeding cats and dogs:
