I like Pics! for the name. Pics or Ban! would also be a good one. Then you could explain it to everyone that sees him. And make sure the vet knows that's all one first name.
Oreo is so clichê. So are Spot and Patches.
Pocket Rocket would be fun if you got an excitable cat.
Oh, and you do have another cat at home for it to play with, right? If not, go back and get another one. It's mean to have only one cat.
