Evil cat

This is Scarface Claw, "the toughest tom in town". When not appearing in Hairy McLary books for young children, he lives across the road from us and goes by the pseudonym of Boston.
He is the reason that we have to have a litter tray in the house. When we had a cat flap he used to wander in in the night, eat all our cats' food and then attack Smidgin on the landing - and even once on our bedroom window ledge. When we started shutting the cat flap at night he would sneak in early in the evening, hide in the attic and pee on our luggage. Then he'd wail to be let out the front door - usually at around 5am. As if we didn't have enough small creatures waking us up in the night as it is.
Now he has taken to sleeping on Chris' car. Pure evil.
