About a year ago an emaciated cat appeared in my garden, he was very “wild” looking (dirty patchy coat). He started trying to steal my cats food - he was in such a desperate state I started giving him a plate of food whenever he showed up. I love cats and would have taken him in and given him a home (my other 2 cats ignore him and wouldn’t have minded) but he is very wild and the the most he will let me do is stroke his head when he eats. He is not neutered. His teeth look quite strong and white so I don’t think he is that old. He is in much better shape now (at least not starving) but I don’t know what to do now...what if I move house? I feel responsible now and don’t think I could just go and leave him to starve again. Any advice?
