Un-spayed females have a monthly menstrual cycle and get terrible PMS! Their first heat cycle is usually at about 12 weeks of age and become sexually active at about five months old. They will have a heat cycle every month for the rest of their lives. And the heat cycles last about 3-5 days.

Do fishes have periods?
Fish do not have periods. They have internal sexual organs and ovaries that produce unfertilized eggs once a year.

Do horses have periods?
Mares normally have 3 or 4 prolonged periods (7–14 days) of sexual receptivity during the vernal transition before the first ovulation of the breeding season occurs. Similar long periods of sexual receptivity normally occur during the autumnal transition between the breeding season and winter anestrus.
