00:00Turtle scales cats have a surprising particularity.

00:03They are almost all females!

00:05Yes, it's all a matter of chromosomes.

00:07In cats, the turtle scale color is related to the X chromosome.

00:11As females have two X chromosomes, they can have both black and red.

00:16Males with only one X chromosome and one Y chromosome

00:19can normally not be tricolor, with the exception of some males.

00:23Some males have a tricolor coat,

00:25but this is a genetic anomaly called Klinfelter syndrome,

00:29which gives it an extra X chromosome, but which also makes it sterile.

00:32Turtle scales cats would have a more exacerbated temperament than the others.

00:37Contrary to popular belief, they are not more difficult than other cats.

00:40Like all cats, they just need love, petting and a corner to sleep.
