Hi, macca, reading your post, it sounds like you put your cat out at night? He's very young for that - have you had him neutered? If not, please do - it's much better for him and he'll stay home at night & not wake you up to be let in! Also, it'll be safer for him, as he won't get into fights with the neighbourhood toms, or stand the chance of being killed on the road at night. It'll also help placate your neighbours if he's neutered & stays in at night. I've got 5 cats, 4 females & 1 wee lad (all "done") but we had all sorts of problems with an un-neutered tom, who came to visit every night, making a h**l of a racket and even got in through our cat-flap, raped my little female cat and pee-ed all over the house!!
