Skunks are a member of the cat family. They can climb over and under fences and fit through the tiniest hole. It is impossible almost to keep them out of your yard.
How Do Skunk Get In The Yard? Do They Climb Or Go Though Hole?
Do skunks climb to get food
I don't know if you saw the John Travolta movie Phenomenon. He was baffled at how a rabbit could mysteriously and repeatedly get into his fenced in garden and eat his vegetables. It was only after everyone thought he had a close encounter that he became super-smart and figured out that the rabbit lived inside the fence and never left. Just hid in his hole. Turned out that it was not a close encounter, just a brain tumor. Oh I have a family of skunks in my backyard they have been there for a very long time.
