Raccoons, bats, skunks, foxes, and coyotes are the wild animals most prone to rabies. Rabies is a viral disease that can be fatal if not prevented. Humans and pets can be given rabies by a rabid animal, so never approach an animal you suspect has rabies. If you suspect a wild animal has rabies, contact a wildlife rehabilitator. 

Symptoms of rabies include: trying to bite, excessive drooling, frothing at the mouth, paralysis, staggering, convulsions, choking, strange noises, aggression, chasing people, and/or fearfulness

A variety of different wild animals carry different parasites, including ticks and different types of worms. Some parasites can be passed onto humans and pets from wild animals, so never approach an animal you suspect has parasites. If you suspect a wild animal has parasites, contact a wildlife rehabilitator. 

Symptoms of parasites include: diarrhea, excessive weight loss, vomiting, worms in feces, visible parasites on the animal, etc.

Do not touch or feed wild animals as this can cause wild animals to lose their fear of humans. Wild animals need to be able to provide for themselves without human interference and aid. Do NOT take wild animals away from their homes or mothers or take them in as pets since this will detrimentally impact the animals ability to survive in the wild, can be harmful to humans, and is also illegal.
