Can a mother cat still produce milk after being spayed?

Spaying, or ovariohysterectomy, is a common surgical procedure performed on female cats to prevent them from reproducing. Many pet owners wonder if spaying a mother cat will affect her ability to produce milk for her kittens. In this article, we will explore the topic of spaying and its impact on lactation in mother cats. By understanding the physiological changes that occur after spaying and the process of milk production, we can address common concerns and provide pet owners with valuable insights regarding the nursing abilities of spayed mother cats.

Understanding Spaying and Its Purpose

Spaying is a surgical procedure in which the ovaries and uterus of a female cat are removed. The primary purpose of spaying is to prevent unwanted pregnancies, control feline overpopulation, and reduce the risk of certain reproductive health issues.

The Process of Lactation in Mother Cats

  1. Hormonal Changes: During pregnancy, a mother cat’s body undergoes hormonal changes that prepare her for the process of lactation. These hormonal signals stimulate the mammary glands to produce milk.
  2. Milk Production: After giving birth, mother cats begin producing milk to nourish their newborn kittens. Milk production is crucial for the survival and healthy development of the kittens.

Effects of Spaying on Milk Production in Mother Cats

  1. Milk Production and Hormones: Spaying removes the ovaries, which are responsible for producing reproductive hormones like progesterone and estrogen. These hormones play a role in stimulating milk production. Therefore, spaying can potentially affect the hormone levels associated with lactation.
  2. Timing of Spaying: The timing of spaying can influence milk production in mother cats. If spaying is performed before or during pregnancy, the hormonal changes necessary for milk production may not occur, leading to insufficient milk production.
  3. Individual Variations: While spaying can affect milk production in some mother cats, individual variations exist. Some spayed mother cats may continue to produce milk, while others may experience a reduction or complete cessation of milk production.

Addressing Common Concerns

  1. Impact on Kittens: If a mother cat’s milk production is significantly affected by spaying, it may have an impact on the nutrition and growth of the kittens. In such cases, supplemental feeding with a suitable milk replacement formula may be necessary.
  2. Early Separation: Early separation of the kittens from their mother may negatively impact their socialization and overall well-being. It is generally recommended to allow the kittens to nurse from their mother for at least the initial few weeks of life, if possible.
  3. Bottle-Feeding: In situations where a spayed mother cat cannot produce sufficient milk, bottle-feeding with an appropriate milk replacement formula is crucial to ensure the kittens receive proper nutrition and hydration.
  4. Pseudopregnancy: In some cases, spayed mother cats may exhibit pseudopregnancy, a condition where they display behaviors similar to pregnancy, including the production of milk. However, this milk is not nutritionally suitable for the kittens.


Q1: Can a spayed mother cat produce enough milk for her kittens?

A: While it is possible for a spayed mother cat to produce enough milk for her kittens, spaying can potentially affect milk production. Monitoring the kittens’ growth and seeking veterinary advice is important to ensure their well-being.

Q2: Does spaying a mother cat affect the quality of her milk?

A: Spaying does not directly affect the quality of a mother cat’s milk. However, hormonal changes associated with spaying may indirectly impact the composition of the milk.

Q3: How long does a mother cat produce milk after giving birth?

A: Mother cats typically produce milk for the first 4 to 6 weeks after giving birth. After this period, the kittens start transitioning to solid food.

Q4: Can a spayed mother cat dry up her milk supply?

A: If a spayed mother cat experiences hormonal changes or reduced stimulation from nursing, her milk supply may decrease over time. However, this is not a guarantee, as individual variations exist.

Q5: Should a mother cat be spayed before or after giving birth?

A: Ideally, it is recommended to spay a mother cat after she has finished nursing her kittens. This allows her to fulfill her maternal duties and provide proper care during the crucial early stages of kitten development.

Q6: Can a spayed mother cat foster and nurse orphaned kittens?

A: Yes, a spayed mother cat can foster and nurse orphaned kittens if she accepts them. The process involves proper introductions and monitoring to ensure compatibility.

Q7: Can a spayed mother cat produce milk if she has never been pregnant?

A: While uncommon, some spayed mother cats may experience pseudopregnancy, where they exhibit behaviors similar to pregnancy, including milk production. However, the milk is not suitable for sustaining kittens.

Q8: Can a spayed mother cat’s milk supply increase with proper stimulation?

A: It is unlikely for a spayed mother cat’s milk supply to increase significantly with stimulation alone. However, providing proper nutrition and hydration can support milk production.

Q9: Can a spayed mother cat’s milk supply come back after drying up?

A: Once a spayed mother cat’s milk supply has dried up, it is unlikely to return. The hormonal changes associated with spaying affect the milk production process.

Q10: Are there any health risks associated with spaying a lactating mother cat?

A: Spaying a lactating mother cat carries some risks, such as increased surgical complications and potential disruptions in milk production. It is generally recommended to spay a mother cat after she has finished nursing her kittens.


Spaying a mother cat may potentially impact her ability to produce milk, as it involves the removal of the ovaries responsible for hormonal stimulation. While individual variations exist, some spayed mother cats may experience a reduction or cessation of milk production. Monitoring the kittens’ growth, seeking veterinary advice, and providing appropriate supplemental feeding if necessary are important steps to ensure their well-being. The timing of spaying also plays a role, as performing the procedure before or during pregnancy can affect milk production. Understanding the effects of spaying on lactation allows pet owners to make informed decisions regarding the reproductive health and care of their mother cats.
