Piómetro in cats – Symptoms and treatment

Despite what is said about the multiple lives of cats, the truth is that cats are extremely delicate animals, that although they have resistance to viral and bacterial diseases, they can suffer certain ailments if they do not pay attention to their health as it should be.

Surely you have heard that if you have a cat and you do not sterilize it, it may eventually develop some diseases related to your uterus and your reproductive system, which sometimes have deadly consequences.

That’s why we want to talk about the pyometra on cats – symptoms and treatment, because it is a disease that can affect your feline friend without you knowing it, being potentially dangerous for her.

What is the pyrometer?

It is a infection that can develop the females of some species of mammals, such as cats, bitches, ferrets and guinea pigs. Consists of the accumulation of pus in the uterus matrix.

In the cats it usually appears in advanced age, generally after the 8 years, although it is also possible that it is developed by young cats that have been given injections or pills to stop heat or other therapies with estrogens and progestogens.

The disease manifests itself suddenly and can result mortal, since the complications involve the appearance of septicemia and peritonitis.

How is it contracted?

The cat may contract some bacteria during the last part of the heat cycle, either the Escherichia coli or other. During this stage of the heat, Progesterone levels They are higher, causing infection.

When the cat is ready to receive the mount of the male, the bacteria take advantage of the opening of the vagina to traverse the body of the animal to the cervix. When a mating occurs in which the fertilization of the ovule is not achieved, the uterus distends and the mucosa that has not been fertilized becomes a channel for the storage of the bacteria.

The disease can also develop from another bacterium that is already in the animal’s blood, vulnerable to the use of hormones administered during a treatment. Or when, due to irregular heat cycles, the uterus degenerates and causes a condition called Cystic Endometrial Hyperplasia (HEQ), which makes the development of bacteria conducive, resulting in a pyometra.

In this way, the cats that can develop pyometra are those that have had a zeal during which fertilization has not occurred, and those that have received therapies that involve the use of progesterone.

Symptoms of the pyometra

The pyramid in cats has general symptoms, and some related to the type of pyrometer that the feline has developed. Among the general symptoms it is possible to mention:

  • Threw up
  • Lethargy
  • Fatigue
  • Loss of appetite
  • Polydipsia, increase in water intake
  • Polyuria, frequent urination
  • Dehydration

On the other hand, the pyrometer can be opened or closed:

  1. Open pyrometer: The abdomen of the pet is distended due to the accumulation of pus inside the organism. The cat excretes through the vagina secretions with a bad smell, either of pus or blood.
  2. Closed pyrometer: When the cat suffers this variation of the disease, the discomfort is even greater, since the abdomen is distended but no secretion is expelled through the vulva. As a result of this, the matrix can burst and produce peritonitis, which is deadly.

Since what is filled with pus is the matrix, and this organ is designed to accommodate the litter during pregnancy, its storage capacity is quite large, causing the pyometra to be perceived only after several weeks have elapsed since the beginning of the pregnancy. infection cycle.

If the disease is not detected in time, as is often the case with closed pyometra, the pus in the matrix can end up transmitting the bacteria to the blood of the rest of the body, causing septicemia due to this general infection, which brings the death of the animal.

It can also unleash a peritonitis if the uterus reaches to distend beyond its capabilities, or if the animal suffers a blow that, due to the swelling, causes the uterus to explode.


Given the suspicion of a pyramid in your cat, you should take it with your veterinarian to perform the necessary tests to check or rule out the presence of the disease.

For the diagnosis to be complete, it will be necessary to perform ultrasounds, x-rays, blood tests and complete chemistry. Only in this way can determine the type of pyometra, the severity of the state of the womb and uterus and the extent of infection, determining whether it has been complicated by damage to the liver, kidneys or other organs.

Treatment of the pyometra

The most advisable thing in case of pyometra is to resort to surgical intervention to remove the uterus and ovaries of the cat, which receives the name of ovarohisterectomine. Before surgery it will be necessary to evaluate how affected other organs are, and to stabilize the body of the animal with antibiotics and a lot of liquid, to fight infection and dehydration.

With surgery, the pyometra infection is eradicated completely, since the organs in which the disease occurs are eliminated. However, if the cat has developed problems in the kidneys as a result of the infection, recovery can be complicated.

However, there is also a drug treatment, by which you choose when the general health of the animal does not allow an operation, or when you want to preserve the reproductive capabilities of the feline. This treatment seeks to expel the pus that has accumulated inside the uterus to then attack the infection. After cleaning the uterus completely, it will be necessary to perform ultrasounds for several months in a row to detect a possible reinfection.

It will be the veterinarian who can suggest the most appropriate and safe method for the animal, according to the complications of the case.


Sterilize the cat avoid this and any other problem related to heat cycles after which a gestation period does not start, so it is the most recommended option. In addition there are a large number of advantages of the sterilization of a cat.

Likewise, it is recommended avoid the use of birth control pills to interrupt the heat. If you do not want the animal to have babies, simply resort to sterilization. The use of hormones, as we have mentioned, can cause the pyometra.

Finally we remember that it is important to take a control over the reproductive system of the cat, in case any disease is suspected. Going to the veterinarian every 6 approximately months is the best way to prevent and detect any disease in time.
