A rather lovelly grey tom cat appers to have taken up residence in our greenhouse sleeping in a cathouse that was vacated when one of our two cats had to be put down in Februaruy. After spending ages sitting at the back door looking longing at our cat's food bowl we finally yielded and fed it. It spends a great deal of time in our garden and the greenhouse and seems desperate for affection (and desperate to get into the house).
It's got a nasty looking tick on its neck, there seems to be a bit of a lump under the tick and a lot of dried blood around where the tick has attached. I've armed myself with some surgical spirit and a tick puller but there's a problem, the cat's clearly very well feed (he's a really big stocky chap) and I'm not sure he's a stray (although I suppose he could be doing the rounds and getting feed at various places), he also looks pretty well groomed. I've feed a stray before and they seem desperate for food, this one seems more desperate for attention. So, should I meddle with, potentially, someone else's cat or leave well alone?
