You don't see hybrid horse and zebra offspring out and about, do you?

A Zorse is a Zorse of course of course and no on can talk to a Zorse of course that is of course unless the Zorse is the famous Mr. Ed.

Yes, I see the Zebra-Horse. A Zorse, huh? I didn't know such a beast existed! Does this happen often in nature? Are these animals sterile? I know that if you mix and horse and a donkey, you get a mule, which I think are always sterile. Please correct me if I'm wrong. ;-)
