Here's why:
* Natural process: Lactation is a natural process triggered by hormones, specifically prolactin, that are produced during pregnancy and after birth. The hormones gradually decrease as the kittens grow and are weaned, leading to a decrease in milk production.
* Nutritional needs: Producing milk requires a lot of energy and nutrients from the mother cat. Once kittens are weaned and no longer need milk, the mother cat's body redirects those resources to other bodily functions.
* Health concerns: Continued milk production after weaning can be a sign of a medical problem, such as a hormonal imbalance. It's important to consult a veterinarian if you notice your cat producing milk after her kittens have been weaned.
Note: Some cats might experience a brief period of "leaking" milk after weaning due to residual hormones, but this should be temporary and not a cause for concern unless it persists.
