Facts Friday

This week's Fact Friday Sarah shares a fact from The Ellen show and Cat town.


Tricoloured cats are always female. Examples of tricoloured cats are Tortoiseshell and Calico. I first heard this fact on Ellen, I'm sure it was during one of her cat weeks but I can't find the clip. Regardless, I fact checked it and its fairly true.

Only 1 in 3,000 tortoiseshell cats are male. This is because two X chromosomes are needed to make the colour. Male tortoiseshell cats have XXY (male cats usually have one x chromosome and one Y) which make them rare and usually sterile. This fascinated me because I happen to have a tortoiseshell cat name Tigris and she is female.
