Ask the Veterinarian/Cat throwing up


Our 5 year old part Main-Coon part mixed breed cat throws up an awful lot, maybe every other time she eats. She's got very long hair.  Occasionally she'll puke up something that looks like hair, sometimes in the shape of the esophagus (or so we think, cylindrical anyhow).  Usually it's just she pukes up undigested food with liquid (presumably stomach juices). We think it's probably hairballs and tried to give her vaseline but she'll have no part of it. Is there a particular food we should use or is there something you can recommend? She's been doing t his for years, though it seems a bit worse lately. We love her but don't want to spend a thousand dollars plus on testing as recommended by the local veterinarian.

Well part of what could be causing her to vomit is what she eats. Since you didn't tell me what she eats I cannot know if that's part of the problem or not.

Long haired cats do vomit up a lot of hair, that's pretty par for them. The tube shaped vomit is almost always hair balls.

However, some foods are very irritating to cats because they are made with poor ingredients and are never the same from batch to batch. Most grocery store foods fall into this category such as Meow Mix, Friskies, etc.

If that is the case, she needs to be switched to a better, higher quality food. High quality foods, such as Science Diet, are made the same from batch to batch-this is called "fixed-formulation." This assures you that your pets food is consistent, as a change in food from bag to bag can cause digestive upsets, especially in dogs.

But cats too, are prone to digestive upsets and one condition cats can get is a low grade, chronic gastritis or worse, pancreatitis. Pancreatitis can be fatal, so if your vet suggests a test (usually a blood panel) to determine how her liver and pancreatic enzymes are doing, it would really be prudent of you to have that done. Caught early this condition can be treated and turned around.

Vomiting is not normal for cats- even if millions of them do it on a regular basis. Some cats benefit from other options, such as elevating the food bowl for those cats that eat too fast.

Regurgitation is very common in cats but it's quite different than vomiting. Cats will regurgitate their food when they eat too fast. It hits a spot in the throat and comes right back up. Sometimes it comes up about 5 minutes later but it's still regurge.

A cat that vomits like yours does really needs to have a small blood panel done to see what condition her kidneys, thyroid, liver, digestive enzymes and and other blood levels are. Certain raised blood values will tell your vet if your cat is having some gastritis issues or if her pancreas is inflamed. These are very important findings. Cats will also chronically vomit from kidney problems, liver problems, colitis (intestinal problems) and certain cancers of the digestive system.

So re-think the food you feed her and take her in for a small mini-panel see what's going on. This will also help to set a baseline for future blood work if nothing is found. That is always wise at 5 years old. She is only two years from being a senior so it's good to know where her levels are now.

Let me know what food she is on and I can point you to a better choice.
