I would have a bateater, I think they're pretty. It would be for just a pet, but I could see it making moving hard (Lacey Act, anyone?). My only thing would be if they have like a higher mortality rate, I would not support it at all, cause that's not needed just to make something a little different.

That said, if I could get a super dwarf retic x burm cross... I would love it. I love the look of burms but they're just so big!
