"The new cat", eh? You're clearly keeping it! I'd definitely keep a cat if I found one, but I live in another country to my two nowadays.
Well, spoke to the wife, and we're going to have to get a litter tray and keep it in a room in the house while we've got it. Nothing much else for it really.
Then take it to the vets and check for a chip and see if the owner turns up.
Don't think it's a stray - there's no collar, but she has a very good coat
There's a kind of 3 way mexican stand off with the other 2 looking at it from different areas in the house. Except that the new cat is still fast asleep, bless it
