Pyometra is a serious and potentially life-threatening condition that affects the uterus of female cats. It is characterized by the accumulation of pus within the uterus, leading to severe infection that can spread throughout the body if not treated promptly. This condition is most commonly seen in middle-aged to older cats that have not been spayed, although it can occur at any age. Understanding pyometra, its causes, symptoms, and treatment options is crucial for cat owners to ensure the health and well-being of their feline companions.

Causes of Pyometra in Cats

Pyometra in cats is primarily caused by hormonal imbalances, particularly those involving the hormone progesterone. After a cat goes through estrus (heat), if fertilization does not occur, the hormone levels can lead to changes in the uterine lining, creating an environment conducive to bacterial growth. The bacteria commonly associated with pyometra are those normally found in the cat’s vagina, but they can become harmful when they proliferate in the altered uterine environment.

Several factors can increase a cat’s risk of developing pyometra, including age, repeated heat cycles without pregnancy, and certain medical treatments that involve progesterone.

Symptoms of Pyometra in Cats

The symptoms of pyometra can vary depending on whether the cat has an open or closed cervix. In cases of open cervix pyometra, pus and discharge may be visible from the vulva, making the condition easier to detect. Symptoms common to both open and closed pyometra include:

  • Lethargy
  • Loss of appetite
  • Vomiting
  • Diarrhea
  • Increased thirst and urination
  • Abdominal swelling or discomfort
  • Fever

In closed pyometra, where the cervix is shut, the pus cannot drain externally, leading to a more rapid deterioration of the cat’s health. This form of pyometra is particularly dangerous and requires immediate veterinary attention.

Symptoms of Pyometra in Cats

Diagnosing Pyometra in Cats

Diagnosis of pyometra is typically based on the cat’s medical history, symptoms, and a physical examination. Veterinarians may also use ultrasounds and X-rays to visualize the enlarged uterus and confirm the presence of fluid. Blood tests can help assess the cat’s overall health and the severity of the infection.

Treatment for Pyometra in Cats

The most effective treatment for pyometra is surgical removal of the uterus and ovaries, known as an ovariohysterectomy or spaying. This procedure not only treats the current infection but also prevents the condition from recurring. In cases where surgery is not immediately possible due to the cat’s health or other factors, veterinarians may use antibiotics and intravenous fluids to stabilize the cat before surgery can be performed. However, these are only temporary measures, and surgery is still the definitive treatment.

Recovery and Aftercare

Post-operative care is crucial for a cat recovering from pyometra surgery. Cat owners should follow their veterinarian’s instructions regarding pain management, wound care, and monitoring for any signs of complications. Recovery typically involves a period of rest, limited activity, and a course of antibiotics to ensure the infection is fully resolved. Most cats recover well from the surgery with proper care.

Prevention of Pyometra in Cats

The most effective way to prevent pyometra is through early spaying of female cats. Spaying removes the risk of hormonal imbalances that can lead to uterine infections, and it has the added benefit of reducing the risk of other health problems, such as mammary cancer. Cat owners should discuss the appropriate timing for spaying with their veterinarian, but it is generally recommended before the first heat cycle.

Pyometra is a serious condition that requires immediate veterinary attention. By understanding the causes, symptoms, and treatment options for pyometra in cats, cat owners can take proactive steps to protect their pets’ health. Early detection and treatment are key to ensuring a positive outcome, and preventive measures, such as spaying, can eliminate the risk altogether. As always, regular veterinary check-ups are essential for maintaining the health and well-being of your feline friend.


Q: Can male cats get pyometra?
A: No, pyometra is a condition that affects the uterus, so only female cats can develop this infection.

Q: How quickly does pyometra progress?
A: The progression of pyometra can vary, but in closed cervix cases, the condition can deteriorate rapidly within a few days. Early detection and treatment are crucial.

Q: Is pyometra contagious to other pets?
A: No, pyometra is not contagious to other pets. It is a condition caused by internal hormonal changes and bacterial growth within the uterus.

Q: Can pyometra be treated without surgery?
A: While antibiotics and supportive care can temporarily manage the symptoms, surgery is the only definitive treatment for pyometra to prevent recurrence and ensure the cat’s health.

By keeping these insights in mind, cat owners can ensure they are equipped to support the health and longevity of their cherished pets.
