You just can't break in to a Tiger's jail cell to treat it like a tiger that lives in someone's living room. I feel very sorry for all involved.
I'm sorry but anyone stupid enough to put their hand in a tiger's cage deserves to get it bitten off.
A toddler managed to climb in to where a gorilla (of all animals) was not to be climbing out of. Zoo's are to blame in both incidents because they must protect these animals from the public.
