Should You Spay or Neuter Your Rabbit? Benefits and What To Know

Spaying and neutering rabbits are surgical procedures that remove a rabbit’s reproductive organs. 

A spay, also called an ovariohysterectomy, removes a female rabbit’s ovaries and uterus, preventing pregnancy and eliminating the risk of uterine and ovarian diseases. 

A neuter, also called castration, removes a male rabbit’s testicles. Because the procedure is less invasive than a spay, males generally recover a little more quickly. 

Both surgeries prevent rabbits from reproducing and reduce reproductive hormones that contribute to many unwanted behaviors. 

Most veterinarians recommend spaying or neutering pet rabbits because it offers several important benefits: 

• Prevents unwanted litters 
• Reduces hormone-driven behaviors such as urine spraying, mounting, and aggression 
• Makes litter box training easier for many rabbits 
• Makes it easier for rabbits to safely bond with companions 
• Protects female rabbits from serious reproductive diseases 
• May help rabbits live longer, healthier lives 

Spaying and neutering don’t merely eliminate the possibility of unwanted litters. They can also have profound positive effects on the overall health of both male and female rabbits.  

• Prevents uterine cancer: One of the biggest reasons veterinarians recommend spaying female rabbits is to prevent uterine adenocarcinoma, a common and potentially aggressive cancer. Studies have found that 50% to 80% of unspayed female rabbits older than 4 years develop uterine cancer in certain breeds. Because this cancer can spread before obvious signs develop, prevention through spaying is safer than waiting until illness occurs.
• Reduces the risk of other reproductive cancers: Spaying eliminates the risk of ovarian cancer and significantly reduces the risk of mammary cancer.
• Reduces reproductive diseases: Spaying also prevents potentially life-threatening conditions such as uterine infections (pyometra), uterine torsion, and other diseases affecting the reproductive tract. In addition, ​​​​it can reduce hormone-related behaviors associated with false pregnancy, including nest building, guarding, and pulling fur. 
• May increase lifespan: By preventing uterine cancer and other reproductive diseases, spaying may help female rabbits live longer, healthier lives. 

Hormones play a major role in many behaviors that frustrate rabbit parents. After surgery, many rabbits become calmer companions while keeping their unique personalities. 

Benefits may include: 

• Less urine spraying and territorial marking 
• Reduced lunging, biting, and hormone-driven aggression 
• More reliable litter box habits 
• Easier bonding with people and other rabbits 
• Less mounting and territorial behavior 

Keep in mind that hormones don’t disappear immediately after surgery.  

It can take four to six weeks for hormone levels to decline, so some behaviors may continue temporarily.  

Although spaying and neutering do not guarantee a reduction in these behaviors, many rabbit parents notice substantial improvements. 

Most rabbits are spayed or neutered between 4 and 6 months of age. 

Male rabbits can often be neutered once both testicles have descended, while females are usually spayed around 5 to 6 months of age. Giant breeds sometimes mature a little later than smaller breeds. 

Your veterinarian may recommend a different timeline based on your rabbit’s breed, size, development, and overall health. 

It’s also important to remember that male rabbits can remain fertile for ​​​​up to six weeks after neutering, so they should be kept separate from unspayed females during that time. 

Before surgery, your veterinarian will perform a physical examination to make sure your rabbit is healthy enough for anesthesia.  

To help minimize your rabbit’s stress before the procedure, some veterinarians may recommend bringing along a bonded companion. 

Unlike dogs and cats, rabbits should not be fasted before surgery because they cannot vomit and need food moving through their digestive tract continuously. 

Most rabbits receive injectable and inhaled anesthesia along with careful monitoring throughout the procedure. 

Many healthy rabbits go home the same day once they are awake, comfortable, and eating. 

The first 24 to 48 hours are the most important part of recovery. 

Your veterinarian will likely send home pain medication and instructions for monitoring your rabbit closely. 

During recovery: 

• Offer hay, water, and favorite foods as soon as your rabbit gets home. 

• Closely monitor eating, drinking, activity, and fecal production. 
• Give all medications, especially pain medications, exactly as prescribed. Rabbits can be very good at hiding pain, making appropriate postoperative pain management especially important.  
• Keep your rabbit warm, quiet, and in a low-stress environment. 
• Limit jumping and vigorous activity for seven to 10 days, or as directed by your veterinarian. 
• Check the incision daily for swelling, redness, or discharge. 
• ​​​​​To minimize stress and prevent aggression or injury to the incision, most veterinarians recommend separating post-operative rabbits from their companions. It is crucial, however, that they can still see, hear, and smell each other, so many pet parents choose to separate them using a wire cage. Follow your veterinarian’s instructions about contact with a bonded companion. Full contact too soon can carry significant post-surgical risks such as incision contamination, dehiscence, and aggression. 

The biggest thing to watch is whether your rabbit is eating. Rabbits who stop eating after surgery can develop gastrointestinal stasis, which can become a medical emergency.  

If your rabbit isn’t eating or producing droppings ​​​​within several hours of coming home, contact your veterinarian right away. 

Like any other surgery requiring anesthesia, spaying and neutering carry some risk.  

​​​​​Rabbits are generally considered higher-risk anesthesia patients than dogs and cats because they become stressed easily and have unique respiratory and digestive needs. 

Fortunately, modern anesthesia, careful monitoring, effective pain management, and experienced veterinary teams have made these procedures safer. 

One of the most important factors in reducing risk is choosing a veterinarian who regularly performs rabbit surgery. 

Not every veterinary practice routinely treats rabbits. 

Look for a veterinarian who regularly sees rabbits or specializes in exotic companion mammals. 

When calling a veterinary hospital, consider asking: 

• How often do you perform rabbit spays and neuters? 
• What type of anesthesia monitoring do you use? 
• Will my rabbit receive pain medication before and after surgery? 
• Do rabbits stay hospitalized until they’re eating? 

Organizations like the House Rabbit Society and local rabbit rescues can also be helpful resources for finding experienced rabbit veterinarians in your area. 

Spaying and neutering are commonly performed in healthy rabbits, but, as with any other surgery requiring anesthesia, there are risks. Choosing a veterinarian experienced with rabbit anesthesia and surgery can help reduce those risks. 

Many rabbits begin acting much more like themselves within 24 to 48 hours. Complete healing of the incision generally takes about 10 to 14 days, although recovery time can vary. 

Spaying or neutering shouldn’t change your rabbit’s fundamental personality. The procedures may reduce hormone-driven behaviors such as spraying, mounting, and aggression.
