Pyometra is a dangerous womb infection in unneutered female cats. Pyometra is uncommon in cats, affecting around 2% of un-spayed cats (queens) by the time they are 13. However, without treatment, the condition is fatal.

Pyometra means ‘pus in the womb’ (uterus) and it's a medical emergency. Cats with pyometra need surgery to remove the diseased uterus. But the operation is risky because your cat is so poorly. Surgery is expensive, and the outlook depends on how quickly the condition is identified and treated. The best way to protect your cat against pyometra is to spay (neuter) her.
