My 13 year old cat, Monkeydo, started throwing up September 3rd. Keeps down very little. He has liver cysts inside and outside which press on his stomach and gallbladder. Makes him nauseous, makes him throw up. Before 2 days ago he loved to drink from the faucet. Now nothing. He was hospitalized for 2 days, got fluids, cerenia, pain meds, and I had started Gabapentin cream as well. He ate nothing for the vet. Now I have him home for the weekend and he is eating nothing for me. So basically he is going without any real nutrients for about 9 days now. His ultrasound saw the cysts were larger than last year, but his lungs, heart, and blood work were all just fine. So I have opted for the surgery they suggested last year which is risky, particularly since no vet I have seen is familiar with this. There is so much to this story but what I really want to know is, can I make him last until Monday when he has his surgery? I'm going to be giving him Sub-Q fluids today and tomorrow. Thanks.
