It's my dream to own a cheetah. People always tell me it's a bad idea because it'll eat me, but they've been kept as pets for thousands of years and since they're pretty much just giant cats they grow a bond to their caretaker and more than likely would not intentionally eat them.
However, I may get one of those shark chain mail suit things to put under my clothing in case it's playing around and bites my arm off.
EDIT: forget it, I looked it up and German Shepherds bite harder than cheetahs. Just gotta keep dem claws trimmed.
