Definition
A gnawing mammal is any mammal that possesses specialized incisors (front teeth) adapted for gnawing or nibbling. These incisors are typically large, chisel-shaped, and continuously growing, requiring the animal to constantly gnaw to keep them worn down. Rodents, like mice, rats, and squirrels, are classic examples. These mammals use their gnawing abilities to obtain food, build shelters, and explore their environment. Think of them as nature's carpenters.
