Quick answer
Muskrats feed on cattails, pondweed, roots, and occasional mussels, adjusting with season, age, and what is abundant in Marshes, ponds, slow rivers, and wetlands across temperate North America. That label is a preferred pattern, not every item an individual might sample.

Muskrat diet overview
Muskrats (Ondatra zibethicus) are best summarised as Herbivore — cattails, pondweed, roots, and occasional mussels. Anatomy and habitat (Marshes, ponds, slow rivers, and wetlands across temperate North America) decide whether they hunt, graze, filter, scavenge, or mix strategies across the year.
How muskrats find food
Energy-rich foods are prioritised when available; lean seasons force broader diets or longer travel. Young animals may eat different items or receive food from parents.
Muskrat role in the food web
As herbivores shaping plants and seeds, muskrats move nutrients and influence prey or vegetation.
Feeding and human conflict
Never feed wild muskrats. Habituation raises injury risk and can lead to lethal management. Captive diets must match species needs, not generic pet food rules.
Wetland engineer
Muskrats excavate burrows into pond banks and build conical lodges from cattails and mud — structures that create habitat for ducks, turtles, and fish. Their feeding opens channels through dense vegetation, maintaining open water in marshes that might otherwise silt over.
Semi-aquatic adaptations
Partially webbed hind feet, a laterally flattened tail used as a rudder, and dense waterproof underfur let muskrats swim efficiently and stay warm in icy water. They can remain submerged for 15 minutes, closing ear flaps and using stored oxygen.

Muskrat FAQs
What do muskrats eat?
Muskrats feed on cattails, pondweed, roots, and occasional mussels, adjusting with season, age, and what is abundant in Marshes, ponds, slow rivers, and wetlands across temperate North America. That label is a preferred pattern, not every item an individual might sample.
What is the scientific name of the muskrat?
Ondatra zibethicus — used in research and conservation listings for muskrats.
Where do muskrats live?
They are associated with Marshes, ponds, slow rivers, and wetlands across temperate North America. Local presence depends on food, cover, and human land use.
What is the conservation status of muskrats?
Listed in our guides as Least Concern. Check the IUCN Red List and national assessments for the latest formal category.
