Yes my wife and I both have Mules, not Jackasses. A mule is a cross between a female horse, "mare" and a male Donkey, a "jack." The Donkeys we breed with to make a Mule are BIG Donkeys. They have to be at least 14.2 hands tall to breed with. Did anyone here know a Mule is the only animal that can go extinct and all you need is a female Horse and a male Donkey to make a Mule again!? Interesting.
Mules aren't a species, can't breed on their own, so can't exactly go extinct. They need to be a distinct species to begin with, capable of breeding in the wild, not some hybrid.
