Good question. I'll see if i can find out.
If you think it's a skunk, you might get a skunk trap. It's basically a trap out of plastic pipe just small enough that the skunk can not lift his tail. Only one good way to empty it though...into a pond...at least that's what our conservation dept guy said. If you trap it in a regular trap, getting rid of it will be real interesting! Keep us posted.
