Nope! The only animals to have periods are simian primates, bats, and the elephant shrew. I am , of course, Not A Scientist, but as I understand it, periods are the result of a sort of evolutionary arms race between the embryo, other embryos, and the mother. The endometrium (uterine lining) is designed to keep the embryo from accessing the mother’s blood supply directly so that the mother has control over the resources she’s dedicating to the pregnancy (the embryo, rudely, developed an aggressive placenta that bores through the endometrium and gets ahold of the mother’s blood anyway). But since the endometrium has such a limited blood supply, it’s prone to tissue dieoff and infection (yikes). Evolution’s solution was to just ditch the whole thing at the end of every ovulation cycle if no pregnancy resulted. So humans and a few other animals get to experience the joy of expelling their uterine lining every cycle, but at least we know that animals like horses, dogs, and cats don’t have to suffer through that.
