Metritis in Rabbits
- See your vet immediately if your female rabbit has bloody or pus-like discharge, belly swelling, weakness, fever, or stops eating.
- Metritis is an infection and inflammation of the uterus. In rabbits, it may overlap with pyometra, where infected fluid collects in the uterus.
- Many rabbits need urgent stabilization plus surgery to remove the infected uterus and ovaries, especially if they are sick, painful, or septic.
- Early treatment improves the outlook. Delays can lead to shock, bloodstream infection, uterine rupture, or life-threatening GI slowdown.
- Spaying before reproductive disease develops is the most reliable way to prevent uterine infection in female rabbits.
What Is Metritis in Rabbits?
Metritis is inflammation and infection of the uterus. In rabbits, pet parents may also hear related terms like pyometra, which means infected fluid or pus has built up inside the uterus. These conditions can overlap, and both are considered urgent because rabbits can become very sick very quickly.
Metritis may happen after pregnancy, after retained fetal or placental material, or when bacteria move into an abnormal uterus. In rabbits, uterine disease is especially important because intact females are also prone to other reproductive problems, including endometrial changes and uterine cancer. That means a rabbit with vaginal bleeding, discharge, or abdominal enlargement needs prompt veterinary evaluation rather than watchful waiting.
Some rabbits show obvious reproductive signs, while others first look "off" in more general ways. They may eat less, hide, grind their teeth, seem weak, or develop GI stasis. Because rabbits are prey animals, even subtle changes can matter.
Symptoms of Metritis in Rabbits
- Bloody, brown, yellow, or pus-like discharge from the vulva
- Blood seen in bedding or mistaken for blood in the urine
- Reduced appetite or complete refusal to eat
- Lethargy, hiding, weakness, or collapse
- Swollen or painful abdomen
- Fever or low body temperature
- Aggression, restlessness, or obvious discomfort
- Infertility, stillbirths, or illness after kindling
See your vet immediately if your rabbit has discharge, stops eating, seems weak, or has a swollen belly. Rabbits can deteriorate fast, and a uterine infection may trigger dehydration, severe pain, GI stasis, or sepsis.
If you are not sure whether the blood is coming from the urine or the reproductive tract, treat it as urgent anyway. Your vet can help sort out whether the problem is uterine disease, urinary disease, pregnancy-related trouble, or another emergency.
What Causes Metritis in Rabbits?
Metritis usually develops when bacteria infect the uterus. In rabbits, this may happen after pregnancy or pseudopregnancy, after retained fetuses or placental tissue, or when the uterine lining has already been changed by age-related disease. Merck notes that metritis in small animals is commonly linked to retained tissue, fetal or placental retention, and postpartum contamination, while rabbit references describe uterine infections and fluid buildup as recognized reproductive disorders.
Bacteria reported with rabbit uterine infections include organisms such as Listeria monocytogenes and Chlamydia species in older veterinary references, but many cases are approached more broadly as bacterial uterine infection rather than tied to one single organism. Your vet may also consider whether there is concurrent uterine hyperplasia, cystic change, abscessation, or uterine adenocarcinoma, because diseased tissue can make infection more likely.
Intact female rabbits are at the highest risk because they still have a uterus and ovaries. Spayed rabbits do not develop metritis of the uterus because that organ has been removed. That is one reason early spaying is recommended for female rabbits that are not intended for breeding.
How Is Metritis in Rabbits Diagnosed?
Your vet will start with a careful history and physical exam. They will ask about age, whether your rabbit is spayed, any recent pregnancy or breeding, appetite changes, discharge, and whether the blood seems to come from the urine or vulva. In rabbits, that distinction matters because urinary tract disease and uterine disease can look similar at home.
Diagnosis often includes bloodwork to look for anemia, inflammation, dehydration, and organ stress. Imaging is also important. X-rays may show an enlarged uterus or help rule out pregnancy, while ultrasound can better evaluate fluid-filled uterine horns, retained material, masses, or rupture. If discharge is present, your vet may also recommend cytology or culture in selected cases, though treatment often cannot wait for culture results.
Because sick rabbits can decline quickly, diagnosis and stabilization often happen at the same visit. Your vet may give fluids, pain control, assisted feeding support, and antibiotics while deciding whether surgery is the safest next step.
Treatment Options for Metritis in Rabbits
Spectrum of Care means you have options. Here are treatment tiers at different price points.
Budget-Conscious Care
- Urgent exam with rabbit-savvy veterinarian
- Basic stabilization such as warmed fluids and pain control
- Antibiotics chosen by your vet
- Syringe-feeding or appetite support if needed
- Limited diagnostics such as focused x-rays or minimum database bloodwork
- Close recheck planning within 24-72 hours
Recommended Standard Treatment
- Urgent exam and full physical assessment
- Bloodwork and abdominal imaging
- IV or subcutaneous fluids, pain relief, and antibiotic therapy
- Ovariohysterectomy to remove the infected uterus and ovaries when the rabbit is stable enough for anesthesia
- Perioperative monitoring and same-day or short-stay hospitalization
- Discharge medications and follow-up visit
Advanced / Critical Care
- Emergency or specialty exotic-animal hospitalization
- Comprehensive bloodwork, repeat imaging, and intensive monitoring
- IV catheter, continuous fluids, warming support, oxygen as needed
- Emergency surgery for severe infection, uterine enlargement, rupture risk, or sepsis
- Overnight hospitalization, assisted feeding, and management of GI stasis or shock
- Possible transfusion or additional procedures in complicated cases

Questions to Ask Your Vet About Metritis in Rabbits
Bring these questions to your vet appointment to get the most out of your visit.
- Do you think this is metritis, pyometra, uterine cancer, pregnancy-related disease, or another problem?
- Is my rabbit stable enough for outpatient care, or does she need hospitalization today?
- What diagnostics are most important right now, and which ones can wait if we need to manage the cost range?
- Do you recommend surgery to remove the uterus and ovaries, and what are the anesthesia risks for my rabbit?
- What signs would mean the infection is spreading or that GI stasis is developing?
- How will you manage pain, hydration, and feeding support during recovery?
- If we start with conservative care, what changes would mean we need to move to surgery quickly?
- Once she recovers, what follow-up do you recommend to prevent future reproductive disease?
How to Prevent Metritis in Rabbits
The most effective prevention is spaying female rabbits before uterine disease develops. VCA advises spaying by about 5 to 6 months of age to help prevent uterine infections and uterine cancer. Timing can vary by breed, size, and your rabbit's health, so your vet should guide the plan.
If your rabbit is used for breeding, prevention focuses on excellent reproductive management and fast response to postpartum problems. Any retained material, discharge, poor appetite, stillbirth, or weakness after kindling should be treated as urgent. Clean housing, careful breeding decisions, and prompt veterinary care after difficult pregnancies may lower risk, but they do not remove it.
For pet rabbits not intended for breeding, early spaying is usually the clearest long-term option. It prevents metritis of the uterus because the uterus is removed, and it also reduces the risk of other serious reproductive diseases that become more common as intact female rabbits age.
