Female ferrets die if they do not mate once they go into heat
When a female Ferret goes in to heat their bodies produce a high amount of the hormone 'oestrogen' which will continue to be produced en masse until she has mated.
Having such high quantities of oestrogen for a prolonged period of will eventually result in Aplastic Anaemia, which is caused by the damage sustained by the bone marrow and blood cells by the high levels of the hormone.
