A few days ago, a little cutie sent me a private message asking me a very "shy" question: "Big Meow, I suddenly found blood on the PP of the little female cat at home. Is her aunt here?"

This... In fact, many novice cats do not know whether they have menstrual periods when they are faced with female cats at home. Through Internet searches, the answers come with various explanations. Therefore, when there are blood stains on the lower body of a female cat at home, she will subjectively think that the cat has a "big aunt", and she will be at a loss.

In fact, many friends are skeptical about whether female cats will menstruate, so we must first understand the following questions:

What does menstruation mean?

If you want to know whether the female kitten will get pregnant, we must first understand what menstruation is. Menstruation is a physiological cycle that occurs in fertile female humans as well as female chimpanzees and other animals. Female horses, cows, pigs, sheep, camels, etc. all have menstrual periods, but some mammals only experience the estrous cycle.

Every month or so in women of childbearing age and female primates, the endometrium will undergo active thickening, gland growth and secretion, blood vessel proliferation, and endometrium shedding, accompanied by cyclic changes in blood outflow. This kind of periodic uterine bleeding or vaginal discharge is called menstruation, which is what girls often call "big aunt"!

Will the cat come to visit its aunt?

In fact, there is no aunty phenomenon in cats! Many dog ​​owners will find that their dogs’ private parts will bleed. In fact, it does not mean that the dog has a aunty! This is a dog The blood mucus discharged by the body before entering estrus is blood mucus infiltrated from the thickened uterine epithelial cells. It is not like the bleeding caused by the shedding of the uterine thickened epithelial cells during menstrual period, and this time happens to be The egg is about to be ovulated. Unlike humans, which only represents the end of menstruation, this moment in dogs indicates that estrus is about to begin.

In the pre-estrus stage of female cats, there is no obvious blood and mucus flowing out like dogs. Even the edema of the vulva will not be obvious or there will be no edema at all. Only occasionally there will be transparent slurry liquid. From the cat It is secreted from the vagina, so many cat owners often do not see the cat come to "aunt". The cat has already entered the estrus period, and there will be many changes in behavior! For example, it likes to be stroked by the owner, and makes calls.Frequent cries at night, frequent urination, etc.

If a female cat is mated to stimulate ovulation, but is not successfully impregnated, the eggs will be destroyed by white blood cells in the uterus and will not be excreted, nor will they bleed like humans. Therefore, the female cat There is no blood menstruation in cats!

Why do female cats bleed without menstruation?

Since the female cat does not have menstruation, why does the poop collector still find bleeding in the cat’s lower body? It is usually due to the following two reasons:

1. Severe cat gynecological diseases

Ahem~ Yes, cats can also have gynecological diseases! If a cat is in heat for a long time but has not been resolved (mated or neutered), it is very likely to cause uterine fibroids in the cat, which may lead to bleeding in the cat. There is a possibility of pyometra, so you must seek medical treatment as soon as possible!

　2. Parasites appear in the cat’s intestines

Some serious parasitic diseases can cause bleeding in cats. If many scavengers are not careful, they will often mistakenly think that blood is flowing out of the cat’s lower body and vagina, so it is very important to deworm cats regularly! But specifically how to deworm and what kind of deworming medicine is good, Da Meow has detailed explanations in previous updates. You can go to Da Meow’s homepage to read it by yourself!

In fact, having said so much, I believe some friends still think that as long as they are mammals, they should have "aunts", but many things cannot be generalized! The reproductive system of cats is completely different from that of humans. Yes, and cats have stimulated ovulation, so it’s not so strange that there is no “big aunt”!

But Big Meow would also like to remind you that if you find that your cat’s lower body is bleeding, don’t take it lightly and take the cat to see a doctor immediately! So as not to delay the condition!
