My mother has an outside cat for about 9 years now he sleeps on the deck and is well fed. A couple months ago he had a bad abscess so we had him trapped. He was neutered had rabies and seemed very happy. Lately I noticed he is getting thinner and sleeps alot. he does eat and seems happy but I feel so bad my mom will not let me touch him as she is ill with dementia. Also I noticed when I go around outside to the deck he does not runaway like he use to. I do not live at my moms condo but go everyday. He was drinking alot of water for a while have not noticed it lately. What should I do. Leave him in peace where he is. Trapping him again will only upset him. It could be age, kidneys I don't know but he is thinner and sleeps alot and has those sad eyes. He also smells my hand through the screen and rubs against the screen in a happy state.
