Well, my experience with groundhogs was less than pleasant. They dug under the house we lived in and eventually caused damage to the house itself. We trapped them and took them miles away and released them.

I see them around where I live now, but I am way out in the country with lots of out buildings etc. for them to live under. I don't know if they eat veggies from gardens, but I suspect they do.

Good luck. What are you going to name it?
