This is a medical emergency, and Zass needs to see a vet now. It's very serious when a cat doesn't eat for longer than 72 hours, as they develop a fatty liver which is fatal without treatment. He could have a severe GI illness, diabetes, kidney disease, liver failure, or even cancer causing his symptoms. He needs veterinary care now, please take him into one.

    Hello, and thanks for using Pet Coach. I'm sorry to hear that Riot isn't feeling well. I'm quite concerned about the symptoms you described. This could be a number of things, but with her age, vomiting, decreased appetite, and hanging around the water dish I'm concerned about the possibility of either advanced kidney disease or diabetes, both of which can be fatal if left untreated and can cause Riot to suffer in the meantime. It is very important that you have her seen by a vet to determine what's wrong; my suspicion is there is an underlying disease process that will not resolve on its own and requires medical attention. Hope this helps.
