Do miniture pigs have periods

Yes, miniature pigs, like other female pigs, go through a reproductive cycle that includes estrus, or heat, which can be likened to a menstrual cycle in other mammals. During this time, they may exhibit behavioral changes and physical signs, such as swelling of the vulva. However, they do not have a menstrual period in the same way humans do, as they reabsorb the uterine lining if not pregnant rather than shedding it.
