Why is my cat vomiting diarrhea-like liquid for 2 days but acting normal?

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.

Thanks for using Petco Pet Education Center, formerly Petcoach! If she is having diarrhea after the treatment, there is likely something else wrong. I would recommend having her re-examined and do further diagnostics like X-rays and blood work to determine why. If she is still eating and drinking and energetic, you could wait until Tuesday. But if she is vomiting, I would have her treated sooner so she doesn’t get dehydrated. Good luck and kisses to Tuffy!

Thanks for using Petco Pet Education Center, formerly Petcoach! He is so handsome! Vomiting and diarrhea can occur secondary to conditions such as inflammatory bowel disease, dietary indiscretion, parasites, among other possibilities. I recommend that you have Kalvin evaluated by your veterinarian for further assessment and treatment. At the very least they can start him on medications to make him feel better and check his hydration status. In the meantime, keep water available at all times to try to prevent dehydration. Good luck and have a good day!

You can wait until 4 pm today since she is acting normal. If that changes or something else occurs before then, then I would recommend going to the veterinarian earlier. I would also bring a stool sample with you to the vet when you go. Thank you for using Petco Pet Education Center, formerly Petcoach.

Thanks for using Petco Pet Education Center, formerly Petcoach! Loss of appetite, vomiting and diarrhea can be observed with many conditions such as gastroenteritis, dietary indiscretion, kidney disease, pancreatitis, among many other possibilities. I recommend that you have Miu reevaluated by your veterinarian for further assessment and treatment as she has not improved in the treatments they have recommended so far. They would be able to check for these possibilities and others depending on the findings on exam. Treatment would be based on findings. Good luck and have a great day! Hoping for a speedy recovery!

Hello, thank you for using PetCoach. I suggest you have him dewormed and I would also start him on a probiotic (Fortiflora). If you do those two things and the diarrhea doesn't start to resolve in a few days then you need to take him to a vet for an exam. ( https://www.1800petmeds.com/purina+fortiflora-prod10376.html ) ( https://www.1800petmeds.com/drontal+for+cats-prod10073.html ) I don't think the oral flea/tick med is the issue but of course it can be. If you use that again in the future and the diarrhea starts again then you can probably confidently say that it is the issue in which case I would stop using it. Usually if that is the case the diarrhea starts within 24 hours of administration. Two weeks later, it is not likely. The new food is also possibly the culprit but again, you didn't switch cold turkey and it doesn't sound like he is eating that much of it anyway. Again, possible but not likely. Hope this helps. Best wishes.

Thanks for using Petco Pet Education Center, formerly Petcoach! I recommend taking Shiro back to the vet with a fresh stool sample to check for intestinal parasites. If normal I would recommend an abdominal X-ray to rule out a foreign body. It may not be the food and there could be something serious. He should not be vomiting daily and I worry he could dehydrate. Good luck and kisses to Shiro!
