The ferret (Mustelapulourius furo) is a mammal belonging to the family Mustelidae in the order Carnivora. The body of a ferret is slightly slender, streamlined, with a round body and no sharp corners or flat areas. Distributed in southern Canada and Oklahoma and Kansas in the United States. Ferrets love to play and live in groups. They mostly sleep throughout the day and prefer quiet environments. They are highly alert to external stimuli. Ferrets lack sweat glands and are not suitable for high temperature environments. When frightened, they will empty their anal glands and secrete musk. Ferrets are carnivorous animals that mainly feed on small vertebrates such as mice and rabbits.
