I plan to get another hamster soon, and was wondering what I might call it. I went through Sonic, Knuckles, Tails and Eggman before briefly considering calling it Darkrai.
However, I now plan to name it Apollo after the Ancient Greek and Roman god of music, light and prophecy.
So, I considered it, but I never have, and most likely never will. It'd be pretty fun, though.
I sometimes call my pet cat (named Toby) Skitty. Just sometimes, though. Not as a proper nickname.
