It was for the best. It ruins the natural system when people feed wildlife, even unaware.

Now I need to discourage the skunks from raiding the cat food on the porch. I've resorted to just feeding them only in daylight, although in the mornings they are lying in wait just outside the door:

You can’t zap skunks. They will spray everywhere.

Overhead sprinklers and a tank full of tomato juice to soak it down after they've sprayed?

That could work. You already have a lot of contraptions in place.

Rube Goldberg would be proud :)
