Had a skunk come up to the tent one night. A skunk don't have to spray anything for you to know it's a skunk. It scratched around on the nylon a little bit, I "gently" tapped it with my boot a couple times, from inside the tent, and it moved on.
I was told by an old timer if you grab a skunk by the tail, and keep his hind legs off the ground, it can't spray you. A couple times I was tempted to see if it was true, but I always chickened out.
