My male Exotic Shorthair cat vomits up pale pink/red watery vomit about once a week. What do you think could be wrong?

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Poor Groucho! The blood indicates stomach lining ulceration. Vomiting once a week is a lot. Possible causes are: food allergy, inflammatory bowel disease, stomach cancer, GI lymphoma, kidney or liver failure, hyperthyroidism. I recommend an exam, full senior blood work and belly X-rays. Sometimes a belly ultrasound is also needed. But he could respond to a prescription diet. I wish you and Groucho the best!
