I have two oddball feline rulers with cheesy names. I've had them for 10 years.
Sasha Miyu - aka La Puss Nikita - Because she stalks her toys and was rather vocal when I got her. Sashi for short.
Diablo - aka Mouse Hunter "D" - Two nights after we got him I dreamt I was in the second level of Dante's Inferno talking to Cleopatra when suddenly the Devil intervened. I woke to a dark furry face and screamed.

I got the $@#$ scared out of me and he got the name Diablo. "D" for short.
