Are all orange cats really male?

: orange cats male

Why: And calico cats female? I just saw this picture:
I think I told Chandler that "fact" a few weeks ago, but I'm not really even sure that it's true.

Answer: Erm, not all: Only something like 80% of orange cats are male. But the calico thing is closer to true - they are almost, almost always female:
To have black and orange in the same cat, you need two X chromosomes. Two X chromosomes mean the cat will be female. Male cats need a Y chromosome and are XY. Occasionally a mutation will arise during embryonic development and a kitten will be born with an extra chromosome: XXY. The two Xs allow for it to be black and orange. The Y makes it a male. This is how you get a tortoiseshell or a calico male cat.
But the thing about this is that you probably can't breed the boy calicos. The same mutation that makes them krazy colors also make them sterile.

The More You Know: Speaking of sequins, those "albino peacocks" you keep seeing are not albino - they are leucistic. The eyeballs of leucistic animals are not red.
Also, I don't know if you know this, but peacocks are total jerks.
