Does Spaying a Pregnant Cat Kill the Kittens?



Cat owners often wonder about the consequences of spaying a pregnant cat. One common concern is whether spaying a pregnant cat will result in the death of the kittens.

In this article, we will explore this topic in detail and provide you with the information you need to make an informed decision.

Understanding Spaying and Pregnancy in Cats

Spaying, also known as ovariohysterectomy, is a surgical procedure performed on female cats to remove their reproductive organs.

It is a common practice to prevent unwanted pregnancies and reduce the risk of certain health issues, such as uterine infections and certain types of cancer.

When a cat becomes pregnant, her body undergoes significant changes to support the growth and development of the kittens. The gestation period for cats is approximately 63-65 days.

During this time, the kittens rely on their mother for nourishment and protection.

Can Spaying a Pregnant Cat Harm the Kittens?

The short answer is yes, spaying a pregnant cat can result in the death of the kittens.

When a pregnant cat is spayed, the veterinarian removes the uterus, which is where the kittens are located. This procedure terminates the pregnancy and prevents the kittens from being born.

It is important to note that spaying a pregnant cat is not a common practice.

Veterinarians typically recommend spaying cats before they become pregnant or after they have given birth and finished nursing their kittens.

However, there are situations where spaying a pregnant cat may be necessary, such as in cases of severe health issues or emergencies.

Why Would a Pregnant Cat Need to be Spayed?

While it is generally recommended to spay cats before they become pregnant, there are instances where spaying a pregnant cat may be necessary.

Here are a few reasons why a veterinarian might recommend spaying a pregnant cat:

  1. Health Issues: If the pregnant cat develops a life-threatening condition, such as pyometra (a severe uterine infection) or eclampsia (a dangerous drop in blood calcium levels), spaying may be necessary to save the mother’s life.
  2. Emergency Situations: In some cases, a pregnant cat may experience complications during labor or delivery. If the mother or kittens are at risk, spaying may be the best course of action to prevent further harm.
  3. Overpopulation Control: In situations where there is an overwhelming number of stray or feral cats, spaying pregnant cats can help prevent the birth of more kittens and reduce the population.

It is important to consult with a veterinarian to determine the best course of action for a pregnant cat’s specific situation.

The Procedure and Risks

Spaying a pregnant cat involves a surgical procedure similar to spaying a non-pregnant cat.

The veterinarian will make an incision in the abdomen, remove the uterus and ovaries, and then close the incision with sutures.

As with any surgical procedure, there are risks involved. The risks associated with spaying a pregnant cat include:

  • Anesthesia complications: Pregnant cats may have a higher risk of complications during anesthesia due to the physiological changes in their bodies.
  • Infection: Any surgical procedure carries a risk of infection. The veterinarian will take precautions to minimize this risk, such as using sterile instruments and providing post-operative care instructions.
  • Bleeding: There is a risk of bleeding during and after the surgery. The veterinarian will monitor the cat closely and take appropriate measures to control bleeding if necessary.

It is important to discuss the potential risks with your veterinarian before making a decision about spaying a pregnant cat.

Recovery and Aftercare

After the spaying procedure, the pregnant cat will require proper care and monitoring during the recovery period. Here are some general guidelines for post-operative care:

  1. Rest and confinement: Provide a quiet and comfortable space for the cat to rest and recover. Limit her activity and keep her confined to a small area to prevent excessive movement.
  2. Pain management: Your veterinarian may prescribe pain medication to keep the cat comfortable during the recovery period. Follow the dosage instructions carefully and monitor the cat for any signs of discomfort.
  3. Incision care: Keep a close eye on the incision site for any signs of infection, such as redness, swelling, or discharge. Follow your veterinarian’s instructions for cleaning and caring for the incision.
  4. Monitor appetite and behavior: Watch for any changes in the cat’s appetite or behavior. If she shows signs of distress, pain, or unusual behavior, contact your veterinarian.
  5. Follow-up appointments: Schedule a follow-up appointment with your veterinarian to ensure the cat is healing properly and to address any concerns or questions you may have.


Spaying a pregnant cat is not a decision to be taken lightly.

While it can result in the termination of the pregnancy and the death of the kittens, there are situations where it may be necessary for the health and well-being of the mother cat.

It is crucial to consult with a veterinarian to assess the specific circumstances and make an informed decision.

Remember, prevention is always better than cure. Spaying your cat before she becomes pregnant is the best way to avoid the need for spaying a pregnant cat in the future.

Regular veterinary check-ups and discussions about reproductive health can help you make the right choices for your feline companion.
