Why is my cat hiding, lethargic, and has diarrhea after food switch?

Poor Sushi! The diarrhea could be due to many conditions including the new diet, bacterial over growth, parasites or even organ disease. If the diarrhea has continued beyond 24 hours, I recommend to have her examined by the veterinarian. With continued diarrhea, there are often bacterial shifts in the gut that will make matters worse regardless of the initial cause. Make sure to bring in a sample of fresh stool. The doctor will check her for parasites and bacterial over growth. Many times a bland diet can help and then a slow, gradual introduction to the normal food can be done. A bland diet can consist of 25% boiled white meat chicken and 75% boiled white rice. This should all be plain. I hope Sushi starts feeling better quickly! Please feel free to post any additional questions.

There can be many causes for the sudden change in activity level, including unhappiness with the new food flavor, pain from arthritis or another source of pain, GI upset from food allergy or dietary intolerance, anemia, constipation, infection, among many others. I would keep a close eye on his food and water intake, and monitor his bowel movements and urinations. If he is not back to himself in 48 hours, or if additional symptoms develop, he should see a vet for and exam and appropriate diagnostics.

Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concern. I would recommend switching to a different food such as a hydrolyzed protein diet and feed this for the next 4 weeks to see if this makes a difference. I would also add in a probiotic such as Purina Fortiflora, which can be found online or at your local pet store. If the vomiting persists or worsens, I would recommend having a veterinarian examine her so that the most appropriate diagnostic and treatment recommendations can be made. Please let me know if you have any other questions or concerns and I would be more than happy to help you further.

I would recommend that you have Alfie examined by a veterinarian. His symptoms could be caused by food intolerance, food allergies, intestinal parasites, inflammatory bowel disease, intestinal lymphoma, hyperthyroidism, systemic disease (liver, kidney, pancreas, diabetes), among others. After a thorough physical exam and review of his history, the vet may recommend bloodwork, intestinal parasite screening, or ultrasound to determine what could be the cause. They may also recommend that you do food trial for possible food allergies.

It sounds as Coco is suffering from a gastrointestinal condition, possibly an infection. it could also be due to ingestion of a foreign body material. i would recommend taking him to the vet the first chance you get, he will need to be checked first, if the vet thinks it's a simple gastrointestinal infection he will need an anti vomiting injection, antibiotics and a special food for a few days in order to get better.

Thanks for using Petco Pet Education Center, formerly Petcoach! If he had a fight with another cat he could have suffered an injury that does not appear apparent at this time. However, it would be best to have him evaluated by a veterinarian for further assessment and treatment. They would be able to examine him to see if he appears to be painful for example which could be a reason to become lethargic and less interactive. He could also be somewhat traumatized by that encounter which he could potentially eventually get over. However, I still think that he should be evaluated. Good luck and have a good night! Hopefully this is nothing to be concerned about.

It definitely sounds like something is bothering Kavek. I would recommend taking him to a veterinarian to get evaluated. He may have an upset stomach or he may have hurt himself. Your veterinarian can perform a physical examination and see what/if any diagnostics are necessary to determine the cause. Thank you for using Petco Pet Education Center, formerly Petcoach.
