On average, they have litters of four to eight pups. Arctic foxes usually bear only four to six young. As with the red fox, litter size increases significantly in years when lemmings are numerous. Although it's hard to predict if you will see any, foxes are curious and may approach your camp. The young become independent in September so you might see them in their quest for food.
Foxes eat lemmings, hares, ptarmigan, bird eggs, decaying flesh from carcasses, and garbage.
The weasel lives wherever it can form a den to raise young and store prey in times of abundance. They den among rock piles, loose earth and both Thule and modern-day houses. When lemmings are abundant, so are weasels. You may see them flashing behind a building, across a street or even between your feet. Although they depend mainly on lemmings, these small but fierce predators will tackle prey up to the size of arctic hares.
