Causes, signs and treatment of pyometra in cats


Pyometra in cats is a disease of the reproductive tract, manifested by inflammation of the uterus. The disease is a type of purulent endometritis. It is very dangerous for the life of the animal, so it requires urgent intervention of the veterinarian. The risk group includes cats of all ages. Sterilized animals without a uterus and both ovaries do not develop this pathology.


Causes of pyometra development are represented by a number of cases affecting the health of the cat:

  • Hormonal malfunctions;
  • Endometritis that has not been completely cured;
  • Activity of opportunistic pathogens;
  • Hormonal medications used by a cat;
  • Uncontrolled mating, including mating with untested animals;
  • Failure to follow aseptic precautions when assisting in childbirth or during heat.


Symptoms of pyometra include:

  1. oily discharge from the genital tract;
  2. enlargement of abdomen, its tightness, painfulness;
  3. increase in temperature;
  4. disorders of the digestive system;
  5. heavy breathing, lack of mobility, apathy;
  6. frequent urination;
  7. thirst with no appetite.


Treatment of pyometra in cats is carried out medically or surgically. By injecting hormonal drugs, the veterinarian tries to achieve purification of the uterus from purulent exudate. Prescriptions are supplemented with antibiotics and symptomatic agents.

Surgical intervention for pyometra involves removal of the affected uterine cavity and both ovaries. If the overall condition of the cat is not severe, the prognosis of surgery is usually favorable. Prevention of pyometra is routine sterilization of cats.
