Why does my cat throw up undigested food after eating but seems fine?

Thanks for visiting Petco Pet Education Center, formerly Petcoach. Vomiting in cats can be caused by several things, but vomiting right after eating does bring to mind a couple of possibilities. But you first have to differentiate whethere whether Coix is vomting (obvious retching and forceful expulsion) or regurgitating (undigested food just seems to come out without much effort). Vomiting can be caused by inflammatory bowel disease, megaesophagus (typically causes regurgitation), a parasitic infection (not as common), or even an underlying congenital disorder. Most of these conditions are treatable. You should first start with some diagnostic testing to gather more information on your specific pets condition. Then we will know what needs to be done for Coix to help control his vomiting episodes a bit better. In general, you can continue to feed smaller portions and go with an easily digestible diet such as limited ingredient diets (i.e. Iams, Purina, Evo). This is something you can easily start while awaiting a proper vet visit and diagnostic work-up for Coix. I hope this helps get you started and best wishes on finding the exact underyling cause for Coix's vomiting episodes. Take care.

It depends on how soon after eating your cat vomits. If food is consumed and then almost immediately regurgitated (still looks whole, not digested), then s/he may be eating too fast. If it is several hours later and the food is partially digested, s/he may have a food allergy or intolerance, a gastrointestinal disorder, or some other underlying medical condition. For cats that gobble their food, it helps to feed more frequent, smaller meals throughout the day. Or you can put a couple balls or small blocks (too large to be swallowed) in the bowl so your cat has to eat around the obstacles. This will slow down his/her eating.

Try feeding smaller, more frequent meals. If Smokey eats fast, try a 'slow feed' bowl to address the issue. Sometimes, switching to a canned food may help. If the vomiting persists or worsens, have him examined by your veterinarian.

It may be a dietary intolerance to the Science Diet food. You can try switching to a different brand or try feeding wet food instead of dry. If Gucci still vomits after trying a different food, then there may be another cause for the vomiting, such as hairballs, acid reflux, eating too fast, or even disorders with the stomach or intestines that delay digestion. You can discuss these possibilities with your vet, and they may recommend medications or diagnostics such as ultrasound or a barium study to see if things are moving through his system with the normal speed or not.

George's intermittent vomiting can be a frustrating problem to diagnose and manage. While eating quickly can cause vomiting, other possible causes of this waxing and waning frequency of vomiting could be related to inflammatory bowel disease or chronic pancreatitis. These conditions can both require fairly extensive diagnostic testing to get a definitive answer, including blood tests, abdominal ultrasound and intestinal biopsies. At this point, you can certainly try to slow down George's eating pace, but you can also consider trying a diet change, as this can help both of the issues I mentioned. If you decide to change his diet, I recommend using a novel protein diet (one protein source/one carbohydrate source), such as Dick van Patten's Natural Balance Limited Ingredient Diets or prescription based formulas. Choose a flavor of food that he has never been exposed to (i.e. venison, rabbit, etc.) and gradually mix his old and new foods slowly over 5-7 days. Avoid feeding any treats or table food while feeding this diet to eliminate any exposure to other foods. It can take 6-8 weeks to determine if a diet change is successful, so don't give up after a few weeks if you haven't noticed a change. If George continues vomiting intermittently on a new diet that he is eating slowly, I would consider taking him back to the vet to discuss further diagnostic testing. I hope that all goes well!

Antibiotics can cause GI upset in cats, so it could be that Korben Dallas was eating less while he was on the antibiotics. Now that he's off the antibiotics, he's feeling better and eating much more quickly. That would be why he's throwing up all of his food. I would try to feed him smaller amounts more frequently to have him slow down his eating. If that doesn't help with the vomiting, I would take him into the vet for an exam, as he could have a medical illness causing the vomiting.

There are a huge number of reasons that a cat will vomit. Since it sounds like Luna is mostly vomiting undigested food, she may simply be eating the dry food too quickly, so canned food is a great idea to try. Canned food is actually more biologically appropriate and better for a cat's health than dry food, so feeding Luna only canned food is a great idea. However, if she continue to vomit while eating canned food only, I would certainly recommend having your veterinarian examine her. Good luck! I hope that was helpful and answered your question.
