Hi everyone. I've never posted in this part of the forums before, but I'm looking for collective wisdom. We have a 12+ year cat with vomiting and diarrhea. Through the last several months, we have determined he has trouble with most foods (especially fish). We have tried hypoallergenic dry foods, all wet food, no grain foods, etc. He did not vomit on the no grain food, but did not eat enough to maintain weight. He actually was slowly starving himself to death (down to 5.5 lbs from 7.5 lbs). we had him on cooked chicken breast for 3 weeks during which he did okay (but he refuses it now) and was gaining. We then tried a green pea and duck formula that seemed fine for 5 weeks. He then started having problems again. We've taken him to the vet twice -1st time, they said hairballs, try hairball remedy, try change in food. Thought anemic, but no signs at last visit. 2nd time (1 1/2 weeks ago), vet noted he had lost his back leg muscles (he had trouble walking), thought maybe stroke or possibly just problem due to loss of muscle-told us we had done everything we could. We now have him on a chicken based wet food. Poops are getting a bit better, but were loose again about an hour ago. He's not making the litter box for poops at all and some for pees (in litter box or pees in bed). He now walks fine again so is a bit better than when I took him to the vet. I'm willing to try him back on cooked chicken breast + taurine which he was doing okay on, but is intensive as I have to feed small amounts throughout the day or on a raw diet. If neither helps, we will put him down. I am, however, having a difficult time with that. any thoughts?
