Each animal has its own distinct personality and you will be able to find a good match if you are patient. Coat colors vary greatly, ranging from white to silver and many shades of browns. Some ferrets may have white patches or stripes. Never purchase a ferret that has not been fixed and de-scented. It is especially important that the females are spayed.
Female ferrets ovulate when they breed.
If the female is not bred, she will remain in heat and can develop estrogen-induced bone marrow depression. This causes anemia and decreased platelet count, which can be fatal. Even when ferrets have been de-scented they still have a distinct scent. Weekly bathing can keep this scent from becoming too strong. Sometimes you can rescue one from a shelter, but be careful that you are aware of the reasons that the animal was sent to the shelter.
