He's a black and white cat with patches of tabby on his head and shoulders green eye and a squint (due to the bad one) very cute litle thing. Not that big considering he's a tom, but then our other two are females and very big so i can't really compare him to them!

Still making myself ill worrying about 'damaging' someone elses pet (I know how i'd feel if someone took it upon themselves to look after one of our other two)

I think as you said we've done about all we can now, checked at the vets for signs, had him scanned for a chip, asked locally and around the village if anyone knows who's he is. I suppose i just need to think that I'm only doing what's best for him.

Might go and pick up a little collar today to give that a go (I'm sure that will make him run a mile!)
