My cat is 15 and much loved. A couple of months ago he had lots of blood in his litter tray. Took him to vet and was given anti biotics..all fine till I noticed he was losing weight. He has started having very loose stools in litter tray and occasional faecal incontinence. I try and clean him but you know what cats are like, we both end up miserable :( . Took him back to vets today and they said he has lost a LOT of weight. Took blood tests. I just don't know what to do. I work looong shifts so really don't want to come home to cat shit everywhere. Don't want to put him through lots of tests, he gets so stressed going to vet. I'm thinking it's the end of the road for him and better now before things deteriorate but it's such a horrible decision to make. Could change cat food to see if that works but I have other cats and leave food out when I'm working so wouldn't be able to guarantee he was eating it. Help!
