Predators beware! Skunks, such as the striped skunks living in the North American forests, come equipped with a foul-smelling liquid that can be sprayed up to ten feet away.

When a predator comes close a skunk will stomp its feet and lift its tail, preparing to defend itself. If the predator doesnt heed the warning signs, the skunk will let loose its putrid-smelling weapon.
