Tortie ragdoll cats aren’t particularly rare. But males are extremely rare. In fact, only about one in 3,000 torties are male.
Tortie ragdoll cats are almost always female because the chromosome that carries the orange or black coat color marker is an X chromosome. Males only have one X chromosome, meaning their coat is either orange or black, but not both. Tortie ragdoll cats have both, which is why a male is rare.
In the rare instance that you find a male, it will be sterile.
The rarest ragdoll cat color is believed to be the cream-colored ragdoll. These nearly all-white cats have ivory points on their head, paws, and tail.
