Boy am I glad to know so many other people also have lots of nicknames for their cats!

Stump is also called Stumpaluffagus, Stump E. Cat, Neko-chan, Buddy, and Pal.

Emmett doesn't answer to anything necessarily, including his name, but I also call him Emmett Boy, Monkey Tail, Emmett Cat, and Emmett Wemmett.
