As a little kitten he was nicknamed Beaker,because he 'meeped'. When he's being a wild child,I say 'Robin Hood' like Alan Rickman in Prince Of Thieves. He thinks it's so funny! When He plays hide and seek,and I can't find him I try to lure him out by opening a can. He's gotten wise to me,though. But a treat bag rustle he CAN'T resist!
Nibbon (when we first got her, before we had a name, I called her "She-Who-Has-Not-Yet-Been-Named", or SWHNYBN, on my blog; a commenter said that the acronym should be pronounced "swish-nibbon", and the "nibbon" part stuck as a nickname)
Itty Bitty Kitty Committee
Butt Cat (when she's being a pain in the butt)
and my version of "off the fish tank", "Mara what are you getting into over there?!?!" >.<
