Despite being given, and using a litter tray, my 15 year old cat has continued to use corners of our bedrooms to wee in. I have tried many things to get rid of the smell in the hope of stopping him doing this, and keeping him shut out of the rooms he favors, although this is hard in a busy family home .
He saw the vet last year, who took bloods, all was normal apart from his amylase level, which the vet thought was linked to his weight ( he's a large cat who has become very inactive). He has been on a urinary care diet, is no longer overweight, but still not very active.
Would it be morally wrong to have him put to sleep, and would a vet think I was heartless ? He is a rescue cat ( have had him for 3 years), so although I do love him, I'm not as attached to him as I could be !
