I'm sorry to hear this, I love kitties :(

How is his activity level? Does he seem tired, lethargic, depressed in addition to the vomiting and lessened food intake?

Has your vet done a full blood workup to check for any nutrient imbalances?

Did your vet check his xray for any damage to the pancreas?

(I am thinking possible pancreatitis, might be something to ask about). Ask for blood workup to check for pancreatic and liver enzymes and check insulin levels.


One of my cats had a couple bouts of gastritis a few years ago - he couldn't keep anything down at all. But I could also visibly tell something was wrong with him because in addition to the vomiting, he was laying around all depressed and sad-looking off by himself (and he is usually down here in the mix with us all the time). So I'm curious if you cat is also just kind of depressed, lethargic, or hanging out alone when he is normally hanging out with you? These are all clues. During this time, I could also see his third eyelid coming up and covering part of his lower eye - this is also a big indicator they feel unwell.

My cat overcame his gastritis but he did have to stay in the hospital for a couple days each time. They gave him fluids and other meds (can't remember them all now) but I do specifically remember giving him generic Pepcid (famotidine) for about a week after getting him home. I would give him a half tablet of Pepcid morning and night, and it really helped to settle his guts. Ask your vet if they think it would be ok to try Pepcid for your cat - it might help a lot for inflammation and reducing stomach acid.

Also check his kidney function - cats with chronic kidney disease are more likely to have elevated acid levels making them more prone to vomiting. A daily dose of a 1/4 of a 10 mg tablet of Pepcid AC (or generic, famotidine) can control this. Some cats feel nauseous without vomiting, which causes a decrease in appetite.
