Foxes
First of all, one of the predators of groundhogs that eat groundhogs is foxes. Foxes are cunning creatures because they consume a variety of both plant- and animal-based foods. Groundhogs are among the smaller animals in the latter. Although they are known to be active at other times of the day as well, these predators with rusty red coats prefer to hunt during dawn and dusk.
In this case, the groundhog does have one clear advantage, and that is its capacity for burrowing. The fox cannot access the groundhog's burrow, which it can dig swiftly. Even though it is cunning and devious, the fox has incredible hearing and makes for an excellent listener. When they hear movement above ground, they will begin excavating in the direction of their prey. Fox attacks are possible on any groundhog since they frequently only wait for a chance to strike, stalk their prey, then pounce.
