Can horses turn into zebras?

[CeruleanFae]

on the cool facts area on the forum once popped up saying along the lines of “horses can rarely grow up to be zebras” and that has been in my head for a long time. I’ve looked through some peoples pets and the pet archive and I have yet to see one. (I also might be blind) if you have one can you please share a link to them? I really want to see a zebra from a horse that originally was not supposed to be a zebra! Thank you!!

(I originally posted this in the wrong sub for, hopefully this is the right place now!)

You can randomly get a zebra in the horse adopts, but you will know when you adopt them. The zebra will be a zebra, not a horse.

Very rarely, you might adopt one of these zebras in your group of monthly horse adopts!

In my How Did You Get Your Most Valuable Pet thread, there's been a few different users that actually adopted a zebra with their horse adopts!! Super lucky!!!
