I don’t think that too many people know of an animal called a zonkey— or the animal called a hebra.
A zonkey is a cross between a donkey and a zebra.
A hebra is what you get when you cross a horse with a zebra.
You can also call them Zebra Hybrids or Hybriods, if it makes you feel any better. (Don’t know why it really would though. Or why you’d feel bad in the first place. 😉 )
