We had a groundhog suddenly make an appearance at the shed in our outer run about a week ago. We've had groundhogs in that spot in the past, but hadn't seen any for about 5 yrs. I know they allegedly are "mostly herbivores" but I've also read where they eat small animals. I read that they don't like the human scent, so I had someone in our family urinate at the hole and I haven't seen the groundhog return lol.
