Calico

What does a calico cat have to do with "red"?
Calico is not a breed of cat, but an unusual coloring occurring across many breeds.

This coloring is caused by a combination of specific genetic traits. Calico coloring is a mix of phaeomelanin based colors (red) and eumelanin based color (black, chocolate and cinnamon). Cats of this coloration are believed to bring good luck in the folklore of many cultures.

Virtually all calico cats are female; a male calico is a genetic anomaly and usually sterile. Producing calico kittens through selective breeding also is nearly impossible due to unpredictable actions of genes and chromosomes when cells multiply in a feline fetus.

A calico cat must be a tri-color, with its three colors in distinct patches, not mixed as in a tortoiseshell cat. To be a true tri-color, a calico cat's colors must be:

  • ~~> white

  • ~~> red or cream; and

  • ~~> black, blue, chocolate, lilac, cinnamon, or fawn.

The variations in color from red and black are caused by a gene which dilutes, or lightens up the basic color, and produces a dilute calico cat, most commonly with a coat of white, cream, and blue.

OK, so this is so funny! I have an alternate-reality blog, all "about" brown! LOL! I LOVE your red! Funny we had the same idea, but what does it say about me that I'd do brown? I'm wondering that myself! Ten years ago, I'd 've done red! Hmmm... May have to figure this out and blog about it! Thanks for visiting us over at AWTY! It's so nice to meet you and your son. Love all your blogs!
