Don't have a firm suggestion, except what comes to your mind when you look at him, and figure out his purrsonality a bit. I love black and white cats- they are usually smart and/or funny and affectionate. Can you tell I have two of these! You can also relate a bit to how they came to you in your life to them. They also start to relate to their names.My examples- b/c I love to talk about my kits!
Zakk-smart, sly, affectionate only at night or when hungry, very dignified.
Rocky- rough & tumble, affectionate, whiny, goofy and clumsy. Has always had a bad eye that gives him a "tough" look IMHO.
Suzie- her name really just came to me. Smart & very shy, a little lady.
Cookie-puss- We didn't name him at first b/c we thought he was going elsewhere. Sweet, goofy,outgoing, affectionate, your typical playful curious kitten. My co-worker who rescued him loves calling people cookie-puss sometimes, my husband and I both like cookies and cookie monster, and he looks like puss & boots from shrek- hence- puss w/out boots.
