Pyometra in Cats

(Left: An x-ray film of a cat suffering from pyometra)

Pyometra is the medical term used to describe an infected uterus. This infection can be open (draining pus from the vagina) or closed (pus is contained in the uterus by a closed cervix).Pyometra can be a life threatening infection and may even require emergency surgery. A closed pyometra is more of an emergency than an open pyometra, since there is no drainage of pus in a closed pyometra. If left untreated, cats become very ill and some may not survive. With early treatment, about 90 percent of affected cats recover.Since pyometra is an infection of the uterus, all unspayed cats are susceptible. Pyometra is uncommon in cats from September to December, when their heat cycles are at rest.

Things to watch for:

- Vaginal discharge
- Lethargy
- Lack of appetite
- Depression
- Vomiting
- Diarrhea
- Drinking excessive amounts of water and urinating often

Different breeders have there own individual approach in handling pyometra. Some would suggest ovariohysterectomy (spaying) and some would try a series of antiobiotics before opting for surgery. In my humble opinion, some queens suffering from pyometra tends to react quite satisfactory to treatments by giving Clindamycin, Amoxicillin or Clavamox. But if the queen is still suffering from pain and infection considering that antiobiotics have been given, spaying should be considered. It is advise that we consult our veterinarians for diagnosis and treatment plans.
