Otters are a species of mammal which exist in the Mouse Territories.
They are intelligent and playful animals and live in dens along rivers and lakes. Unlike other mustelids, otters will not regularly prey on mice, so the majority of their diet consists of fish. While active year-round, otters prefer the spring when their young are born.
- Otters are a part of the mustelid family, which includes animals such as badgers, weasels, martens, ferrets, fishers, and wolverines.
