Metritis in Cats
Metritis, a uterine infection that usually occurs within a week after a cat gives birth, is symptomized by an inflammation of the endometrium (lining) of the uterus due to a bacterial infection. It can also develop after a natural or medical abortion, miscarriage, or after a non-sterile artificial insemination. The bacteria that are most often responsible for infection of the uterus are gram-negative bacteria like Escherichia coli, which often spreads into the blood, causing a blood infection. The infection may lead to sterility, and if left untreated, septic shock, a lethal condition, may follow.
Symptoms and Types
- Discharge from the vulva that smells bad; discharge with pus, or pus mixed with blood; discharge that is dark green
- Swollen, dough-like abdomen
- Dehydration (the skin stays tented for a few seconds when pinched)
- Dark red gums
- Reduced milk production
- Lack of appetite
- Neglect of kittens
- Increased heart rate if the bacterial infection has become systemic
- Difficult birth
- Prolonged delivery, perhaps with a large litter
- Obstetric manipulation
- Retained fetuses or placentas
- Natural or medical abortion, miscarriage
- Natural or artificial insemination (rare)
Your veterinarian will perform a thorough physical exam, including a chemical blood profile, a complete blood count, an electrolyte panel, and a urinalysis. These tests will help your veterinarian to determine whether the bacterial infection has spread to the bloodstream, where the infection might have originated, and how dehydrated your cat is. You will need to give a thorough history of your cat's health, onset of symptoms, and possible incidents that might have preceded this condition.
Diagnostic tools, like radiograph and ultrasound imaging, will allow your veterinarian to visually examine the interior of the uterus for any retained fetuses or birth matter, excess fluid accumulation, and/or abnormal amounts of abdominal fluid production due to uterine rupture.
A sample of the vaginal discharge will also be taken for cytologic (microscopic) examination. A culture of both aerobic and anaerobic bacteria (bacteria that lives with oxygen, or without oxygen, respectively) will be used for identifying the bacterial populations present in the blood, and a sensitivity of the isolated bacteria will be performed so that the most appropriate antibiotic treatments can be prescribed.
