How Do Cats Have A Menstrual Cycle?

Cats have a menstrual cycle when they are in heat.

Cats have a menstrual cycle that is very similar to humans. The average cycle is 28 days long, with ovulation occurring around day 14. However, unlike humans, cats do not have a regular cycle and can ovulate multiple times per year.

The feline menstrual cycle is controlled by hormones, with the main one being estrogen. This hormone is responsible for the development of the eggs in the ovaries and the thickening of the uterine lining. Around day 14 of the cycle, estrogen levels peak and trigger ovulation.

Once the egg is released, it travels down the fallopian tube and into the uterus. If it is not fertilized, the egg will disintegrate and the uterine lining will be shed. This is what we call a “period.”

If the egg is fertilized, it will implant itself in the uterine lining and begin to grow. The lining will then continue to thicken to support the developing fetus. Cats typically give birth around 63 days after fertilization.

What Do Cats Eat During Their Menstrual Cycle?

Cats eat during their menstrual cycle in order to replenish the nutrients that they have lost during their period. Cats typically eat more during their menstrual cycle than they do at other times, so it is important to make sure that they have access to fresh, nutritious food.


Cats have a menstrual cycle that is similar to that of humans. However, there are some differences. For example, cats do not have a menstrual cycle every month. Instead, they have a heat cycle that occurs every two to three weeks. During the heat cycle, the cat’s ovaries produce eggs that are released into the fallopian tubes. If the egg is fertilized by a sperm, it will implant itself in the lining of the uterus and the cat will become pregnant. If the egg is not fertilized, it will be shed along with the lining of the uterus during the cat’s next heat cycle.
