I picked my cat names by mostly color and/or something unique. My cats are:
Baby (brown tiger tabby with full rear white boots and white front socks)
Rocky (a beauitful cream and shades of grey tabby - his swirl pattern looks like rocks I've seen in Earth Science)
Cinder (all medium grey medium long hair)
Calliope (was given to me with that name - medium long haired white cat with brown tabby splotches)
Pike (short haired white with brown tabby splotches)
Boy (all red tabby)
Mama (had total of 6 kitties - she's a short hair tortoise shell)
Silky (medium long haired - all light grey with white chest and tummy)
Tux (medium long haired - all black with white chest and tummy)
Cirrus (cream and light red tabby - almost looks cream or white)
Moon (all black)
Snowball (white body with light red seal points (tail, ears and nose)
Stripe (red tabby with white tummy and socks)
