While most people have pets that are cute and cuddly, others have animals that would like nothing better than to bite someone's face off! We're not talking about the occasional bad dog, feral cat or ill tempered bird. We're talking about cold blooded mad as hell reptiles! Take for example this Chameleon named Gringo that just woke up and hates to be disturbed. It's never a good ideal to sass a chameleon, or really any creature, but these guys can get real nasty. Usually their bark is worse than their bite...Usually!
