People call me Dr. Cat, after the popular anime/webcomic character since I've always used cat themed icons, and have two rescue kitty companions for life.
Also I ride a Tiger (promise that's not intentional! I just liked the bike!)
and was obsessed with calvin and hobbes as a kid, and also had a pet stuffed toy tiger I used to talk to.
KittenMeat I think came because of a silly name of a font I saw online, and it sounded like a good punk rock band name. I was also playing the game fallout at the time, and you had the whole "a boy and his dog" theme with your pet, dogmeat.
The whole "a boy and his cat" thing became funny to me if your pet was called kittenmeat.
