Why Is My Cat Being Mean To Her Kittens? Understanding Feline Behavior

For any doting cat owner, the sight of their beloved feline giving birth to kittens can be heartwarming. However, if the mother cat starts to act aggressively or “mean” toward her kittens, this can raise concerns. Why does this behavior occur, and what can you do about it? This article will delve into the intricacies of feline maternal behavior to provide some insights.

1. Natural Weaning Process

One common reason a mother cat may seem mean or aggressive toward her kittens is due to the natural weaning process. Around 8-10 weeks of age, the mother will start distancing herself to encourage her kittens to become more independent. This may involve swatting, growling, or hissing if the kittens try to nurse or become too clingy. It’s essential to understand that this behavior is instinctual and aimed at promoting the kittens’ independence.

2. Stress and Anxiety

Cats, like humans, can get stressed. A new environment, the presence of other pets, or even too much human intervention can make the mother cat anxious. In response, she might display aggressive behavior to protect her kittens from perceived threats, even if those threats are benign.

3. Health Issues

If a mother cat is in pain or discomfort, she may lash out or become irritable. Conditions such as mastitis (inflammation of the mammary glands) can cause pain and make nursing kittens unbearable for the mother. It’s crucial to monitor the mother’s health closely and consult a vet if you notice any unusual behavior or signs of illness.

4. Overstimulation

Kittens are playful and energetic. Sometimes, their constant demand for attention, nursing, or play can become overwhelming for the mother cat. In such cases, she might show signs of aggression to set boundaries.

5. Rejection of Weak Kittens

In nature, a mother cat may sometimes reject or act aggressively towards kittens that are weak or ill. This behavior, though hard for us to understand, has evolutionary roots. By focusing on the stronger kittens, the mother ensures the survival of kittens with the best chances. If you notice a kitten being consistently rejected or harmed, it’s imperative to intervene and consult a vet.

6. Mating Behavior

If a mother cat goes into heat shortly after giving birth, her behavior towards her kittens may change. She might become more irritable and aggressive as her body gears up for another potential mating.

How to Address This Behavior?

  • Provide a Safe Space: Ensure the mother cat has a quiet, comfortable space where she can relax with her kittens without disturbances.
  • Limit Handling: While it’s tempting to interact with the kittens frequently, too much handling can stress the mother. Limit interactions, especially during the early weeks.
  • Monitor Health: Keep an eye on the mother cat’s health and the kittens. If you notice any signs of illness or abnormal behavior, consult a veterinarian.
  • Separation: If the mother cat’s behavior is excessively aggressive and poses a danger to the kittens, consider separating them for short durations. This gives both the mother and kittens a break. However, ensure that the kittens are adequately fed and kept warm.
  • Seek Expert Advice: If you’re uncertain about the mother cat’s behavior, consult a vet or an animal behaviorist for guidance.


Mother cats, like all creatures, have their ways and reasons for certain behaviors. While some actions may seem “mean” to us, they can often be attributed to natural instincts, stress, health issues, or overstimulation. It’s essential to observe, understand, and provide the necessary support for both the mother cat and her kittens. With patience, care, and understanding, you can ensure a harmonious relationship between the mother cat and her kittens.
