I'm tempted to add several of these to the shortlist (see two posts below), but I think it's only Sid Vicious and Tilly who really make the grade. Tilly is obviously a comically ineffectual name for a hard cat, but I don't think I've ever seen a feline look so menacing - haunting, even - whilst damp. It's also been suggested by my closest advisors that Castro should be going on the list, but I get the sense that, as fuming as he looks in this pic, two minutes after it was taken he'd reverted to being a, well, pussycat.
