Cats need titles

I decided my cats must need aliases. Wallop should be called 'The Shredder' because he digs his teeth and claws into the yarn and tries to destroy it. Bob should be called 'Stringslayer' because he cannot resist pouncing on any moving string in his vicinity. And Rocky should be called 'The Assassin' because he let's you pet him until you are lured into complacency, then he lashes out with his claws.
