Pyometra in Rabbits: Uterine Infection in Female Rabbits
- See your vet immediately if your unspayed female rabbit has bloody or pus-like discharge, stops eating, seems painful, or has a swollen belly.
- Pyometra is an infection of the uterus. In rabbits, surgery to remove the infected uterus and ovaries is usually the main treatment, with supportive care before and after.
- Rabbits can hide illness until they are very sick. Delays raise the risk of sepsis, shock, GI stasis, and a harder recovery.
- Diagnosis often includes an exam, abdominal imaging such as X-rays or ultrasound, and bloodwork, although rabbits may not show a strong white blood cell increase even with infection.
- Typical 2025-2026 US cost range for diagnosis and treatment is about $900-$3,500+, depending on stability, imaging, hospitalization, and whether emergency surgery is needed.
What Is Pyometra in Rabbits?
Pyometra is a serious infection inside the uterus of an intact female rabbit. The uterus fills with infected fluid or pus, and the rabbit can become weak, painful, dehydrated, and dangerously ill. In some rabbits, the cervix stays open and you may notice discharge. In others, the cervix is closed, so the infection stays trapped inside and the belly may enlarge without obvious drainage.
This condition is most often seen in unspayed adult female rabbits. It can happen on its own, but it may also occur alongside other uterine disease, including endometrial changes or uterine tumors. That overlap matters, because intact female rabbits are already at high risk for reproductive tract disease as they age.
Pyometra is not something to monitor at home for a few days. Rabbits can decline quickly, and reduced appetite can trigger gastrointestinal stasis, which adds another layer of risk. Early veterinary care gives your rabbit the best chance for a smoother recovery and helps your vet decide whether surgery, stabilization, or more advanced monitoring is needed.
Symptoms of Pyometra in Rabbits
- Bloody, brown, yellow, or pus-like discharge from the vulva
- Reduced appetite or not eating
- Lethargy, hiding, or less interaction than usual
- Swollen or enlarged abdomen
- Weight loss or poor body condition
- Pain when picked up or a hunched posture
- Fever or low body temperature
- Dehydration
- Straining, messy rear end, or urine staining that seems unusual
- Collapse, weakness, or signs of shock
Some rabbits with pyometra have obvious vaginal discharge, but others do not. That is especially true if the cervix is closed and infected material cannot drain. In those cases, the first signs may be vague: not eating, sitting still, grinding teeth, or seeming bloated.
See your vet immediately if your rabbit has any discharge from the vulva, a swollen belly, reduced appetite, weakness, or sudden behavior changes. Emergency care is especially important if she is cold, limp, breathing harder than normal, or has stopped passing normal stool.
What Causes Pyometra in Rabbits?
Pyometra develops when bacteria infect the uterus. In rabbits, this usually happens in an intact female whose uterus is still influenced by reproductive hormones. Those hormonal changes can make the uterine lining more vulnerable to infection and fluid buildup.
In some rabbits, pyometra may be linked with underlying uterine disease, including cystic or thickened uterine tissue, retained secretions, or uterine tumors such as adenocarcinoma. That is one reason bloody discharge in an unspayed rabbit should never be brushed off as a minor issue.
Age increases risk because reproductive disease becomes more common over time in intact does. Poor overall health does not directly cause pyometra, but dehydration, delayed care, and stress from pain or not eating can make the rabbit much sicker once infection starts. Your vet may also consider other causes of discharge or abdominal enlargement, including urinary tract disease, pregnancy-related problems, or uterine cancer.
How Is Pyometra in Rabbits Diagnosed?
Your vet will start with a physical exam and history, including whether your rabbit is spayed, how long signs have been present, and whether there has been discharge, appetite loss, or belly enlargement. Because rabbits often hide illness, even subtle changes can matter.
Diagnosis commonly includes abdominal X-rays and/or ultrasound to look for an enlarged fluid-filled uterus and to help separate pyometra from pregnancy, uterine tumors, bladder problems, or other abdominal disease. Bloodwork may be recommended to check hydration, organ function, anemia, and infection-related changes. In rabbits, normal or only mildly changed white blood cell counts do not rule out serious infection.
If your rabbit is unstable, your vet may begin warming, fluids, pain control, and assisted feeding support before completing every test. In many cases, the diagnosis is strongly suspected from the exam and imaging, then confirmed when the infected uterus is removed during surgery and, if needed, submitted for pathology.
Treatment Options for Pyometra in Rabbits
Spectrum of Care means you have options. Here are treatment tiers at different price points.
Budget-Conscious Care
- Urgent exam with a rabbit-savvy vet
- Basic stabilization such as warmed fluids and pain control
- Abdominal X-rays, with ultrasound only if needed to clarify findings
- GI support if appetite is reduced, including syringe-feeding plan when appropriate
- Same-day ovariohysterectomy when the rabbit is stable enough
- Take-home pain medication and 1 recheck
Recommended Standard Treatment
- Urgent exam and full pre-op assessment
- Bloodwork plus abdominal imaging, often X-rays and/or ultrasound
- IV or subcutaneous fluids, pain control, and GI support
- Ovariohysterectomy to remove the infected uterus and ovaries
- Perioperative antibiotics when indicated by your vet
- Hospital monitoring through recovery, with discharge medications and follow-up visit
Advanced / Critical Care
- Emergency or specialty hospital evaluation
- Expanded bloodwork, repeat imaging, and intensive monitoring
- IV catheter, active warming, oxygen support if needed, and aggressive fluid therapy
- Emergency ovariohysterectomy in a medically fragile rabbit
- Overnight or multi-day hospitalization with assisted feeding and close GI monitoring
- Pathology of removed tissue and management of complications such as sepsis, anemia, or severe ileus
Cost estimates as of 2026-03. Actual costs vary by location, clinic, and individual case.
Questions to Ask Your Vet About Pyometra in Rabbits
Bring these questions to your vet appointment to get the most out of your visit.
- Do you think this is pyometra, uterine cancer, or another reproductive problem?
- What tests do you recommend first, and which ones are most important if I need to keep costs focused?
- Is my rabbit stable enough for surgery today, or does she need to be stabilized first?
- What are the anesthesia and recovery risks for my rabbit based on her age and condition?
- What pain control and GI support will she need before and after surgery?
- Will you recommend antibiotics, and if so, for how long?
- Should the removed uterus be sent for pathology to check for cancer or other disease?
- What signs at home mean I should call right away after treatment?
How to Prevent Pyometra in Rabbits
The most effective prevention is spaying before uterine disease develops. Spaying removes the uterus and ovaries, which prevents pyometra and also greatly lowers the risk of other serious reproductive problems in female rabbits. In the U.S., routine rabbit spay cost ranges are often around $200-$300 at many clinics, though rabbit-savvy and regional pricing can be higher.
Talk with your vet about the best timing for your rabbit. Many healthy female rabbits are spayed when they are young adults, but the right plan depends on age, body condition, and your vet's comfort with rabbit anesthesia and surgery. If your rabbit is older and still intact, it is still worth discussing risk versus benefit rather than assuming it is too late.
Prevention also means paying attention to early warning signs. Any bloody vulvar discharge, reduced appetite, weight loss, or abdominal enlargement in an unspayed rabbit deserves prompt veterinary care. Catching reproductive disease early may allow a safer surgery and a less complicated recovery.
