Aplastic Anemia in Ferrets







Aplastic anemia in ferrets refers to bone marrow suppression, resulting in a complete loss of red blood cells in the bone marrow. If an unsterilized female comes into heat, she will stay in heat indefinitely and during this period, her estrogen levels will remain high and be very toxic to her bone marrow. This can be fatal to your ferret.

Some symptoms of aplastic anemia in ferrets to look out for:

Severe anemia
Swollen vulva
Pale gums
Lethargy
Hair loss

There are 3 methods of getting a jill out of heat.

  • Mating her with a full male (if you want to breed)
  • Taking her to the vet for a “jill jab”
  • Mating her with a vasectomized male (to get her out of heat)

Breeding ferrets is not like breeding cats or dogs. Many things can go wrong during and after your jill’s pregnancy, so if you value your girl, please don’t consider using her to breed from.

Pseudo-pregnancies arise from taking your jill to a vasectomized hob and I have known jills to come back into season after going through that period. Of course, that means taking the jill back to the vasectomized hob and going through the whole mating process again. It seems pretty unfair to make your girl go through that again and again.

I have taken one jill to the vet for a jill jab. She was a discarded ferret and was so heavily in season that there was no way she would have been able to last out the mating game. It worked fine, but there have been stories of the injection not doing what it should.

The best thing to do for your girls is to get them sterilized and then you won’t have to worry!
