My adult cat vomited after eating kitten food. Is it serious?

Thanks for using Petco Pet Education Center, formerly Petcoach! I would wait another 24 hours. If when you transition her to canned food she starts vomiting again, I highly recommend that you have her evaluated by a veterinarian for further assessment and treatment. Some possibilities include gastroenteritis, pancreatitis, food sensitivity, among other possibilities. Good luck and have a wonderful day!

Thank you for contacting Petco Pet Education Center, formerly Petcoach with your question about Buddy. How lovely of you to take in this stray kitten!! Yes I suspect it's the kitten food causing Buddy to have an upset stomach and vomit. Sudden changes in diet can lead to these symptoms. Feed him a bland diet of boiled white meat chicken (no bones or skin) in small amounts a couple times a day for a few days, the start slowly adding in his normal diet. If he refuses to eat the bland diet, vomits the bland diet, stops drinking water, starts vomiting water, continues to have diarrhea, has blood in his stool, and/or becomes very lethargic, he will need to see a vet immediately. I hope this helps!

A sudden change of food will cause GI upset in cats, which is what it sounds like is happening with Jericho. When you do a sudden change in food, it's recommended to do it slowly. Because she is still occasionally vomiting, I would try a home remedy to see if that settles her stomach. I recommend withholding food for 12-24 hours, then feeding a bland diet of boiled white meat chicken (no bones) in small amounts several times a day for a couple of days. Then slowly add back in her normal diet. If the vomiting continues in the absence of food, she vomits the bland diet, develops diarrhea, stops drinking water, starts vomiting water, or becomes very lethargic, she will need to see a vet right away.

Hi, thanks for using PetCoach! Causes of vomiting in kittens are: intestinal parasites, viral or bacterial infections, ate something causing a blockage, food allergy/intolerance, hairballs or reaction to a new treat/food or table scraps. If Mau is still eating and active I would try to get him on 100% kitten food. Some cats vomit more on canned and vice versa. So have both available. Chicken isn't a balanced diet for a cat. You can also try some laxatone in case he has hairballs. If he stops eating or continues to vomit I would have him rechecked. Your pictures are adorable and from what I can tell Mau is likely pure bred Persian! http://pet-supplies.drsfostersmith.com/search?w=laxatone%20for%20cats

Poor thing! I would continue with the baby food but start mixing some mild canned cat food in. Start with a very small amount and work your way to a predominate cat food mixture. I would also make sure she is dewormed at least twice as many young kittens have GI parasites that can make them vomit (in severe cases)

Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concern. If he is otherwise normal and still eating / drinking, I would withhold food for at least 8 hours and initiate a bland diet as outlined below. If he continues to vomit even on the bland diet or he worsens, I would get him examined by a veterinarian so that the most appropriate diagnostic and treatment recommendations can be made. I hope this helps guide you in the right direction. Please let me know if you have any other questions or concerns and I would be more than happy to help you further. GENERAL INFORMATION A bland diet is a diet that is soft and highly digestible. It is low in fiber, fat and protein and is high in carbohydrates. Bland diets are generally composed of a single carbohydrate source and a single lean protein source. The most common bland diet is boiled rice and boiled lean chicken breast, without skin and bones. Since bland diets are low in fiber, stool production slows and defecation is less frequent. Bland diets are fed to rest the gastric system and to help promote normal stool formation. Animals that are physically sick should not be fed bland diets as a method of treatment. PRIOR TO FEEDING A BLAND DIET Pets should be fasted for 12 to 24 hours. Young animals should not be fasted for more than 12 hours. Fasting will allow the intestinal system to relax and minimize acid secretions that may irritate and inflame the intestinal lining. During the fast small amounts of water or ice chips may be provided. Never fast a sick animal, it may cause disease progression and death. BASIC BOILED RICE AND CHICKEN BLAND DIET RECIPE CARBOHYDRATE SOURCE: Boiled white rice LEAN PROTEIN SOURCE: Chicken breast, no skin and bones BOILED RICE: 1 part white rice with 3 parts water boiled for 20 – 25 minutes or until the rice is easily crushed. BOILED CHICKEN: De-fat chicken breast and boil in water for 10 – 15 minutes or until the chicken meat is easily pulled apart and cooked all way through. MIXING INSTRUCTIONS: Finely chop the lean protein and mix 2 cups carbohydrate source and ½ cup lean protein source. STORAGE INSTRUCTIONS: Bland diets can be premade and stored in the refrigerator for a maximum of 48 hours. The bland diet can be cooked in a batch and frozen in feeding sized portions to minimize preparation time. Thaw and warm the frozen diet prior to feeding. PERMITTED LEAN PROTEIN SUBSTITUTIONS Pork loin, egg whites, low fat cottage cheese. 7% low fat hamburger, plain low fat yogurt. PERMITTED CARBOHYDRATE SUBSTITUTIONS Boiled potatoes, boiled spaghetti, Minute rice. PERMITTED COMMERCIAL BLAND DIETS Science Prescription Diet I/D, Eukanuba Veterinary Diet Low Residue, Royal Canin Veterinary Diet Intestinal HE. FEEDING INSTRUCTIONS Estimate 25% of your animal’s diet and feed that amount of the bland diet every 6 – 8 hours. Smaller animals will require less and larger animals will require more adhering to the same carbohydrate to lean protein source ratio. The bland diet should be fed for 4 -5 days with no treats or other food sources until stools are firm. TRANSITION BACK TO A NORMAL DIET Never transition back to a regular diet rapidly. Transition back to the regular diet over a 1 week period. Start by adding 25% of the regular diet to 75% of the bland diet and feed that combination for 2 days. If stools continue to be firm then continue substituting the regular diet in 25% increments and feeding the combination in 2 day time intervals until the diet is 100% regular diet. Minimize treats for 1 week after moving the diet back to 100% regular diet.

withhold food for 12 hours then offer him boiled boneless chicken and rice every 6 hours in small portions. if he is eating and not vomiting, continue with this diet for 2 days. After 2 days, you can put him back gradually on his normal food. If he continues vomiting or is not eating, take him to the vet to get treatment.
