What are Pus in the Uterus?

You’ll notice several symptoms, among them a foul-smelling pus coming from your pet’s vagina. When you notice that she’s sick, take her to the vet immediately so she can be treated. If left untreated, the underlying infection can spread to other parts of your chinchilla’s body, becoming potentially fatal.

Pus in your female chinchilla’s uterus is a serious condition that develops after she has developed a uterine inflammation called “metritis.” Pus in the uterus is called “pyometra”.

Symptoms of Pus in the Uterus in Chinchillas

You’ll notice several symptoms when your chinchilla develops pyometra:

  • Watery, foul-smelling pus
  • Stained fur around the genital area
  • Rough fur
  • Weight loss
  • Increased urination
  • Fur-chewing around the flank and abdomen
  • Fever
  • Elevated white blood count
  • Inflamed uterus

Causes of Pus in the Uterus in Chinchillas

Your chinchilla can develop pyometra from one of several conditions:

  • Infection within reproductive tract
  • Uterine lining wears down from influence of progesterone (female hormone)
  • Estrogen weakens the uterus
  • Retained placenta after pregnancy

A female does not need to have a prior breeding history to be vulnerable to pyometra. Infection can be spread by males with several mates (harem).

Diagnosis of Pus in the Uterus in Chinchillas

Your ability to observe exactly what your chinchilla is doing (her behaviors) and in the symptoms she’s experiencing will help your vet to make the correct diagnosis. 

He will complete a physical exam to determine whether she is ill or if the pus is actually a normal, yellow discharge (which is a normal part of her breeding cycle). In addition to palpating the abdomen, the vet may use an ultrasound to examine the uterus and perform lab test on samples of the chinchilla’s vaginal discharge, blood, and urine to determine the nature and origin of the infection.

Treatment of Pus in the Uterus in Chinchillas

Once your vet has determined that the cause of your chinchilla’s illness originates in her reproductive system, he’ll have to perform an ovariohysterectomy. This is the surgical removal of both her uterus and her ovaries, also known as a “spay”. At this time, there are no other effective treatments; antibiotics are typically not effective, and once a chinchilla has suffered one bout of pyometra, she’ll be vulnerable to subsequent infections. It’s best to spay her early in her illness before she becomes too weak to recover fully.

Your vet will recommend spaying your chinchilla because of the danger that the infection could cause sterility or migrate to other areas of her body, making it a potentially fatal infection. 

Recovery of Pus in the Uterus in Chinchillas

Once your chinchilla has received a diagnosis of pyometra and recovered from her surgery, she will be normal in all respects, except for her inability to breed. As long as receives early treatment, she should make a full recovery. Carefully follow your veterinarian’s instructions for post-operative care and implement any recommended changes to the chinchilla’s living environment.
