Overview of Feline Pyometra Infections

Feline pyometra is a life-threatening infection in a cat’s uterus.  It is potentially fatal and commonly occurs in middle aged to older cats that have not been spayed.  Most occurrences take place within 60 days of their last heat cycle. 

Clinical warning signs of a feline pyometra infection can include, but are not limited to the following:

• Elevated White Blood Cell Count
• Anorexia
• Enlarged Abdomen
• Increased Water Intake
• Excess Urination
• Dehydration
• Fever
• Lethargy
• Inappetance
• Enlarged Uterus
• Odorous Vaginal Discharge
• Weight Loss

A cat exhibiting these warning signs should be examined by a veterinarian immediately.  A veterinarian can perform a thorough examination including laboratory testing to verify the presence of a bacterial infection.  During the examination, the veterinarian may be able to feel an enlarged uterus.    Radiographs or ultrasounds can often reveal the presence of an enlarged uterus.  In severe cases, toxins may infect an animal’s kidneys and liver.

Surgical removal of the ovaries and the infected uterus is highly recommended in cases of feline pyometra.  The infection will necessitate the administration of antibiotics and pain medication before and throughout the surgery and recovery period.  Prevention of feline pyometra can be accomplished through spaying female cats.
