Mammals are rarely consumed by river otters and are not a major dietary staple.Mammals that are preyed upon by otters are characteristically small or are a type species found in riparian zones.[The few occurrences of mammals found in the river otter's diet include: Muskrats (Ondatra zibethicus); Meadow Voles (Microtus pennsylvanicus); Eastern Cottontails (Sylvilagus floridanus); and Snowshoe Hares (Lepus americanus).
There are varying records of otters preying upon beavers (Castor canadensis). Otter predation on beavers has been reported in the southern boreal forest of Manitoba.Trappers in Alberta, Canada commonly assert that otters are major predators of beavers.A 1994 river otter study reported findings of beaver remains in 27 out of 1,191 scats analyzed.However, many other studies did not report any findings of beaver remains in the scat sampled.
(Scat is animal droppings)
Other web sites also say that river otters will sometimes kill muskrats or beavers to take over their dens/lodges. Survival of the fittest.
