Cats in heat should not bleed from their vulva.for this reason, if we observe vaginal bleeding in cats we should understand that it is not part of the natural menstruation process and implies there is an issue which needs to be dealt with. Instead, dogs have an estrous cycle, more commonly called a heat cycle. What do these seemingly disparate animals have in common?

Most other female animals don't bleed outwardly like us. The system is designed to. Even among those that give birth to live young as we do, only a handful of species menstruate.

Over 100 million animals, including dogs, mice, rats, cats, monkeys, rabbits, birds, among others are killed in laboratories for drug, chemical, food, and cosmetics testing every year. A menstrual cycle is most common in primates. All other placental mammals have an estrous cycle.

This phase starts when an egg from the previous cycle isn’t fertilized. It would seem that it would then be a disadvantage to evolutionary survival for female organisms to menstruate. The menstrual phase is the first stage of the menstrual cycle.

These hormones are responsible for developing and maintaining female sexual traits, as well as maintaining a pregnancy. It seems the list of animals that menstruate is quite short: Wounded animals seem to make the best prey and predators seem to have a heightened awareness for the smell of blood.
