Bacterial Uterine Infection (Metritis) in Cats How To Recognize and Prevent Metritis In Cats

Bacterial Uterine Infection (Metritis) in Cats

Metritis in cats is a disorder whereby a female's uterus becomes infected with dangerous bacteria. We discuss this disease further in this article.

What is Pyometra?

Bacterial uterine infection, or metritis, or pyometra, is a serious health concern for female cats. It is a condition in which the uterus becomes infected by harmful bacteria, causing inflammation and, in some instances, pus accumulation. Cats of any age can develop metritis, although female unspayed cats over six are especially susceptible.

This article will further inform cat owners about the ailment and its possible repercussions. We will examine the causes, symptoms, diagnosis, treatment, and prevention of bacterial uterine infection in cats.


There are several possible causes of pyometra in cats, including:

  • Hormonal changes: Fluctuations in hormone levels, particularly the hormone progesterone, can create an environment in the cat’s uterus that is more prone to infection.

  • Poor immune system: Cats with compromised immune systems, such as chronic illnesses, are more likely to get bacterial uterine infections.

  • Retained placenta: A portion of the placenta may stay in the uterus if a cat struggles to birth all of her kittens, creating a favorable environment for bacterial growth.

  • Prior reproductive issues: Cats with difficult deliveries or stillbirths during past pregnancies may be more prone to bacterial uterine infections.

  • Bacteria: Escherichia coli, Staphylococcus, and Streptococcus are a few of the bacteria that can cause uterine infections in cats.

  • Age and reproductive history: Older, unspayed female cats and those with many litters or never given birth are more likely to experience bacterial uterine infections.

Symptoms of Pyometra in Cats

The signs of pyometra in cats can vary based on the gravity of the infection but may include the following:

  • Increased thirst and urination

  • Lethargy

  • Vomiting and diarrhea

  • Loss of appetite

  • Abdominal distension and pain

  • Cat discharge in heat

  • Female cat bleeding

  • Increased panting or rapid breathing

  • Dehydration

  • High fever

Pyometra In Cats Treatment

Depending on the severity of the infection and the cat's general condition, treating bacterial uterine infection in cats frequently entails a mix of medication and surgical procedures. The following are a few potential treatments:

  • Antibiotics: Antibiotic usage is essential in the management of bacterial uterine infections. The kind of bacteria causing the infection will determine the precise antibiotic provided. However, Doxycycline or Clavamox may be prescribed as deemed fit by the vet.

  • Fluid therapy: For the cat to regain hydration and electrolyte balance if it is dehydrated, intravenous fluid treatment may be required.

  • Surgery: In more severe cases, surgery may be required to remove the infected uterus (a procedure called an ovariohysterectomy).

  • Supportive care: The female cat may need supportive care, such as pain management or nutritional support, to aid in her recovery.

  • Monitoring: The cat will need to be closely watched throughout and after the course of treatment to make sure the infection has been completely treated and to deal with any potential consequences that could surface.

Prevention Tips

Many proactive steps must be taken to prevent bacterial uterine infection in cats, such as:

  • Spaying: The best strategy to avoid bacterial uterine infections in cats is to spay them. This procedure removes the cat’s uterus and ovaries, removing the risk of uterine infections and reproductive cancers.

  • Proper hygiene: Maintaining proper hygiene, including regularly cleaning your cat's litter box and keeping her living space clean, can help minimize the risk of bacterial infections.

  • Proper nutrition: Feeding your cat a healthy, balanced diet can help boost her immune system, making her less prone to infections.

  • Treatment of reproductive problems quickly: If your cat is pregnant or has any problems giving birth, such as a retained placenta or a difficult birth, you should take her to the vet immediately.

  • Monitoring for infection symptoms: Be on the lookout for any symptoms, such as discharge from the vulva, lethargy, or loss of appetite. If you detect any odd signs, contact your veterinarian right away.

By taking these preventative steps, you may lessen the possibility that your cat will get a bacterial uterine infection and guarantee her ongoing health and well-being.
