Acute Metritis in Cats

What is acute metritis?

Acute metritis is an inflammation of the lining of the uterus (endometrium) postpartum which causes systemic illness. It is most commonly due to bacterial infection. It can be caused by retained placentas or kittens, contamination of the birth canal during delivery (unsterile fingers or instruments), prolonged labour or unsanitary conditions during delivery. Left untreated, septicemia (bacterial infection of the blood) or toxemia can occur.

It is always prudent to have your veterinarian perform a complete physical check of your cat within a day or so of her giving birth to check for possible problems and a good idea to watch for fever in the queen after delivery.

What are the symptoms of acute metritis?

Symptoms usually occur between 12 – 96 hours following birth. Acute metritis is a life-threatening medical condition and veterinary attention must be sought if you notice any of the following symptoms:

How is acute metritis diagnosed?

Your veterinarian will perform a physical examination of your cat and obtain a medical history. The fact that she has very recently given birth would certainly raise his suspicions of acute metritis.

He may wish to perform the following tests:

  • Complete blood count – This will show an elevated level of white blood cells.
  • X-Ray to check for retained fetuses/placentas.
  • Ultrasound may be performed to check for retained placentas or fetuses.
  • Cytologic examination of the discharge and a bacterial culture so that the appropriate antibiotic can be administered.

How is acute metritis treated?

  • Broad spectrum antibiotics to treat the underlying infection.
  • IV fluids to treat dehydration.
  • If necessary, evacuate the uterus of retained placenta, unborn kitten
  • It may be necessary to perform an ovariohysterectomy.
