Skunks are virtually blind, not being able to see much beyond 15 feet which is also the limit of their spray. Before they spray they will usually stamp their feet, raise their tail, and make sounds like a very mad cat.
I was able to trap 1 that was living under my garage. I thought we were all in trouble when my cat decided to investigate the caged animal, but the skunk never sprayed. I picked up the cage (placing a piece of cardboard between the skunk and I just in case) and released it in the back yard.
I see them walking down the road occasionally (during the day this can be a sign of rabies since they are nocturnal). They don't seem to be too scared of anything.
