Female ferrets (jills) are '''induced ovulators'''. Ovulation occurs 30-40 hours after copulation. Failure to mate can result in a prolonged oestrus for the duration of the breeding season. The '''high levels of oestrogens''' produced may cause bone marrow suppression with leucopenia, [[thrombocytopenia]] and aplastic anaemia. | Female ferrets (jills) are '''induced ovulators'''.
