menstrual cycles

Question
do rabbits start theyre period?

Answer
Dear Danelle,

Rabbits do not have a menstrual cycle, nor do they bleed from the vulva when they are healthy.  If your rabbit is bleeding from the vulva, she may have uterine cancer or hyperplasia (pre-cancer), and she needs to be spayed as soon as possible to prevent the cancer from spreading.

You can find a good vet here:

Hope that helps!
