While I was searching for nice horsey videos (again), I stumbled upon this video, which shows a lady training with a zebra. Now, I know that, without the stripes, zebra looks like a donkey. Is it possible to ride a zebra and even jump with it? Or is this just a painted donkey? Have you seen anything like that in real life?
