Are calico cats always female?

Answer by  mammakat (11147)

I've raised calicos and torties, so I've looked into this. Yes, they are usually female. And I've found that callies and torties almost always have a marmalade male in their heritage, or give birth to marmalades. It's some kind of genetic thing. However, I have had a few males in each litter. Color is a sex-based trait.

Calico cats are ALMOST always female; the gene for the color pattern "calico" is EXTREMELY rare in males. It's just the way the genes split - its very rare for that color pattern to show up in a boy!
