Galictis cuja, like most species, is active at night or at dusk, though some also forage during the day. Many species use burrows dug by themselves or by other animals as their nests. Many are primarily terrestrial, and their slender bodies allow them to burrow into burrows to hunt, while some species often live in trees. Many species of ferrets are excellent swimmers, especially those of the Luna subfamily and mustelids. They generally prefer to live alone, and use secretions from their anal glands, urine, and feces to mark their territory. They have a particularly developed sense of smell, which they use to hunt and communicate with other species. They also have good vision and hearing. Many mustelids use the foul-smelling secretions from their anal glands as a defensive weapon.
The diet of the small nest weasel is not much different from that of the large nest weasel. Both are hunters who will not refuse anything. They will dig holes to prey on small animals. In some parts of America, the small nest weasel is kept as a pet.
The small nest weasel is mainly carnivorous. They also eat more or less plants, depending on the species and in different seasons. The diets of different species within the family vary greatly. Many weasels prey on rodents that are larger than they are. For example, martens prey on hares that are much heavier than they are, and martens even attack reindeer. The main sources of meat in weasels are various vertebrates, including small mammals, birds and their eggs, reptiles, amphibians and fish, as well as insects, crustaceans, worms, etc. Plant foods include fruits, walnuts, tubers, etc.
Protect wild animals and eliminate game.
