The amazing weasel must have sex or it will die.

Ferrets, also known as ferrets. In this species of ferret, when in heat, the females must have a 'husband', otherwise they will die in pain and swelling.

This is a medium sized weasel with brown and black fur.

The ferret, scientifically known as Mustela putorius furo, is a medium-sized weasel with brown, black, white, or merle fur.

In ferrets, females that are not sexually satisfied during their heat will die. The cause lies in their genitals. If they are not allowed to mate, the female ferret's genitals will swell, eventually becoming infected and possibly leading to death. Not only that, if female ferrets are not allowed to have sex, they will become severely anemic and their bone marrow will be damaged.

In addition, ferrets are famous for their amazing (prey) skills. When detecting a rabbit from afar, ferrets roll around and dance continuously to attract the rabbit's attention, making the rabbit lose its guard, slowly approaching and jumping up to bite the rabbit to death.

Ferrets are weasels that have been domesticated as pets for many years.
