Gators are a fact of life in Florida and young males and some older bulls are on the move finding their own territory and prospective mates. Gators in the wild are afraid of humans and avoid contact, but when fed by humans they lose their natural fear and become a nuisance and dangerous to you and pets. There is a death penalty for gators labeled nuisance.
Please do not feed them! Tell your guests the same thing. It is not cute to feed an alligator, it is dangerous and you are imposing a death penalty on the gator.
