Yes some pems can be born tailless, but it's not as likely here in the US as it is in England. In England it's illegal to doc tails, so their trying harder to breed for that trait. Breeders in the us look for other qualities over naturally docked tails, cause they can just have the tails docked by a vet. I thought Ein's looked natural too, but hers is in fact docked. :( I didn't know this about the breed until after I got her.
