Some of these animals include; raccoon, red fox, owls, hawks, american bald eagles, common snapping turtles, bullfrogs, largemouth bass, cats, dogs, and even sometimes people.

Other roles in the ecosystem
As well as being an important part of the food chain muskrats serve other roles in the ecosystem. Muskrats influence the composition of local plant communities. This is important because it keeps one plant from overpopulating and lets new plants grow.
