I'm glad I'm not the only one with this problem! Seafarer - I think "Jumbo nuts" lives near me!! The little old lady down the hill from me took pity on a poor, starving ginger kitten about 3 years ago (he was so hungry, he was scavenging the lambs' tails when they were docked). She took him in and looked after him, but unfortunately never had him neutered. I got so fed up with him breaking in through my locked cat flap when he grew up, beating up my cats and spraying all over the place. He must stay out at night, whereas my lot are always indoors, because we only ever see him late at night or early in the morning. He got a nasty shock once, though, when he chased one of my old girls in (she'd only popped out the back for a quick pee!) and was confronted by Elsa - large, hairy German Shepherd, who adores her own cats, but isn't over keen on interlopers! She didn't hurt him (I think she was more surprised than he was!), but the cat flap was locked to "in only" and he was doing a great impression of Garfield, trying to get out...!! He crashed his way out in the end, before I could help. I thought it would teach him a lesson, but no - he still comes over here, although he hasn't been in the house since.
