Today I surprised a woodchuck/groundhog in my garden.. He was a big fat adult and he ran off and literally LEAPED over a 4 foot fence!! I couldn't believe my eyes! This is Super Woodchuck! I didn't notice a little cape on him but he must have had one. I don't know what to do next. Does Agway sell Kryptonite?

I really don't know what to do - my fence is 4 feet high and goes a foot below ground to keep them from digging under and I've been trying to figure out for months how they're getting in, and now that I've seen it with my own eyes, I'm stumped.

Has anyone ever seen such an athletic woodchuck before? What's the solution?

Thanks in advance.
