Scarface Claw lives

In an article that sounds like the Divers Grey St neighbours there is a sign up in a New York street warning against the monster cat that lives in the neighbourhood"if this is your cat do you know how aggressive it is?" How angry do you have to be to put up a notice like this.

In case we forget the Divers cat (which Tony calls a crat because it does look more rat like than catlike) is called Genghis and they have had delegations from the neighbours because of Genghis' aggressive nature.

All does remind me of "the toughest Tom in town" from Hairy McLairy books - Scarface Claw

What happens when Hairy and friends meet Scarface?
