Most ferrets that are sold as pets are already spayed or neutered. The main reason is that ferrets can be unpleasant when they come into heat. Their fur can become greasy. They become smelly and so does their urine. Males start marking territory and can be aggressive. Luckily, most people don’t have to deal with ferrets that are in heat.
Breeding & Mating
Ferrets come into heat based upon the amount of daylight and do not breed year round. They usually breed when the days get longer and there is more daylight, so spring and summer is the mating season for ferrets.
The male’s testicles will drop and become larger. Females will have the vulva swell and become large. Both can have strong body odor and greasy smelly fur.
Mating can be violent. The male chases the female, can drag her around, bites her neck, and can even draw blood. The mating process is often very noisy and frightening.
Birth & Babies
Around 40 to 42 days after a successful mating occurs the babies, called kits, will be born. There can be as few as one kit or well over a dozen, but 6 to 8 would be a more normal litter size.
The babies are born with their eyes and ears sealed shut. They are pink with white fuzzy fur and will be completely dependent on their mother.
After about three weeks the kits will start eating some solid food, but will still depend on their mother for milk. Once they are six weeks old they should be completely weaned and will soon be able to find a new home.
