As someone, who holds a M.Sc. in Animal Biology, colour me skeptical.
I’d need to see the actual data before I’d take this article any more seriously than the kid in the playground, who swears up and down that the second cousin of his mother’s hairdresser’s lawyer owns a “Cabbit”. :P
(all those “Cabbit” videos invariably turn out to be tailless cat breeds)
Jackalopes have been around for a long time, though. I’ve seen pictures on postcards, and even a stuffed jackalope head once.
Supposedly pampas foxes are closer to jackals than to true foxes.
