Mrs. Spit and I have two very friendly cats. Brothers, but you'd never know it to look at them. The little guy is a 10 pound basement cat - i.e. all black - while the bruiser is 20 pounds of tabbyness. Honest, he's only 20, though we thought he was pushing 30 until we weighed him the other day.
Today I ran across a rather fascinating image, showing a break-down of cat colouration pretty much from A-Z, and then some.

All I can say is the following:
1. I had no idea of the variety in cat colouration.
2. I have no idea where our tabby falls in that mix!
Clearly someone had some time to figure this out.
