The weasel has a docile personality and is loved by many pet lovers. They are very small, only 40 cm in length including their tails, and the males are larger, weighing only about 400 grams.

The weasel has short and flexible legs and a small and soft body. As long as the head can be drilled through, the body will pass unhindered. Each spring, the first litter of lemmings provides essential rations and breeding for weasels before large numbers of migratory birds arrive at the North Pole. Future generations have laid a strong foundation.
