Grison

Grison 

a genus of predatory mammals of the family Mustelidae. Its members are similar to polecats in their size, body build, and way of life. The body is 40–55 cm long, the tail is 16–19 cm long, and the animal weighs up to 3 kg. The body is elongated and close to the ground. The snout, neck, and belly are dark brown, and the upper part of the body and the tail are grayish; there is a broad white stripe across the forehead. There are two species: G. vittatus and G. cuja. They are found in America, south of Mexico. They inhabit both forest and open country and catch small animals and birds. When in danger they hide among stones or the roots of trees, simultaneously spraying a sharp-smelling liquid from their anal glands in self-defense. In October two to four young are born. Grisons that live near human dwellings cause substantial damage to poultry farming. They are relatively easily tamed and are sometimes used instead of cats to exterminate rats. Grisons are hunted for their fur.
