My indoor cat feels hot and is throwing up. What could be wrong?
Hi and thanks for using Petco Pet Education Center, formerly Petcoach! Sorry to hear about Scratch. I think you mean he feels very warm and has a fever, in addition to vomiting. I would advise getting him to your veterinarian as soon as possible if the clinical signs persist, worsen, or other signs develop. Vomiting causes fluid loss and electrolyte loss and can lead to dehydration and weakness. Vomiting can be caused by inflammation, infection, dietary problems (including dietary indiscretion or eating things pets are not supposed to eat, food sensitivities/allergies), ingestion of foreign bodies or exposure to toxins, bacterial overgrowth in the gut, problems in the stomach, intestines, or even problems outside of the intestinal tract/stomach including pancreatitis, kidney/liver problems, metabolic disease (diabetes,etc), endocrine diseases (thyroid or other hormone problems), etc. A thorough history and physical exam with resultant diagnostics such as fecal tests, blood tests, and more imaging studies such as x-rays/ultrasound to try to determine what is going on.
Vomiting and a fever would tend to indicate an infection. I would be worried about pancreatitis, kidney/liver/gallbladder problems, etc. Good luck with Scratch. I wish you and him Happy Holidays together.
