My cat was otj for over 1 year and was doing fine. I took to a new vet a few weeks ago and she prescribed him novifit for his senility, said he has a slight heart murmur and beginning stages of renal failure.. Last night he was sleeping with me and it smelled like he threw up but there was no throw up. He was drinking this morning, at about 1/4 can of fancy feast small can with some treats. Then he seemed weak this evening and wouldn't sit down the whole way, sitting on his full foot. I tested his blood sugar and it was 165... He appears dehydrated. He ate a 1/2 teaspoon of baby food but really isn't drinking water. We are buying some tuna hoping he will drink the juice... Any ideas of what this is? Dka?? If so this came out of nowhere?!?... My other cat that passed from ska and fatty liver did not have the breath smell... I'll likely take him to the vet tomorrow but wanted to see if any had any thoughts on what this is..?
