Vaginal Discharge in Cats

Vaginal discharge is defined as an abnormal discharge coming from the vagina. Unlike humans, cats don’t menstruate, any discharge from the vagina needs to be seen by a veterinarian.


  • Pyometra: Infection of the uterus which occurs in unspayed females.
  • Acute metritis: Inflammation of the postpartum uterus.
  • Vaginitis: This is an inflammation of the vagina. It can descend into the uterus if left untreated, causing pyometra. So fast veterinary attention is vital.
  • Lochia: Normal postpartum discharge. This is greenish in colour, should not have an unpleasant odour and should stop within 7 – 10 days.
  • Cancer: Uterine, ovarian.
  • Spontaneous abortion (miscarriage): This is the spontaneous end of a pregnancy at a stage where the unborn kittens are too immature to survive.
  • Foreign body.


Yes, other than a vaginal discharge, other symptoms to look out for may include;

  • Excessive licking of the genital area
  • Fever
  • Loss of appetite
  • Lethargy
  • Disinterest in kittens (if the cat is a new mother)
  • Polyuria/polydipsia (excessive thirst and urination) 

What should I do if I notice my cat has a vaginal discharge?

It is important you seek veterinary care immediately. Failure to find and treat the cause can be life-threatening.


Your veterinarian will perform a complete physical examination of your cat and obtain a medical history from you. Some tests he may wish to perform include:


Obviously, treatment depends on the cause. If the cause is a bacterial infection then your veterinarian will prescribe antibiotics.


  • IV fluids to treat dehydration
  • Ovariohysterectomy
  • Antibiotics

Acute Metritis:

  • IV fluids to treat dehydration
  • If necessary, evacuate the uterus
  • Antibiotics
  • It may be necessary to perform an ovariohysterectomy


  • Find and treat the underlying cause
  • If it is bacterial, prescribe antibiotics

Spontaneous abortion:

There is no treatment available. But do take your cat and the aborted contents to the veterinarian.


Foreign body:

Surgical removal of foreign body


Lochia is a normal part of the postnatal period but the owner should keep a close eye on the discharge to ensure the amount tapers off over 7-10 days, there is no odour and that the cat is not displaying any symptoms of acute metritis such as fever, loss of appetite etc.
