Black kitty of course (just kidding) - seriously, someone who took one of my kittens - they named him Kitty Kitty - ARE YOU KIDDING ME?? that's just awful. But it could be worse, apparently their other cat's name is puss puss.

OMG! Your kitty may have a name by now, but I was just talking to FH last night about how if I got another cat I was going to name it Crookshanks or Scabbers after Harry Potter. Then I thought of just calling it Potter because that's a really cute name in itself.
More HPesque names:
Jinx Magic Misty Hagrid Albus
Someone else said this but Nimbus would be really cute too.
How bout Deuce or Ace, King of Hearts, king for short.
I know this is wrong and I love them but I cannot resist. "Montecore" that is the name of the tiger that attacked sigfreid or roy. Again I do Apologize for my sense of humor. I still like the name.
