I quite like unassuming, commonplace "person names" for cats. One of my mates has a cat called Dave, which suits him (the cat) down to a tee.
Too soon to tell if yours could be a Gary or not, but it's an option.
Ridiculously cute anyway. So jealous of everyone with their feline companions here. Also, is he a polydactyl cat, or has he just not not grown into his mitts yet?
