Why Do Mother Cats Attack Their Older Kittens? [Video]

Are you perplexed as to why your mother cat is attacking her older kittens? It’s an intriguing aspect of feline behavior that leaves many pet owners puzzled. This article will shed light on the reasons behind this seemingly bizarre action, ranging from territorial issues to maternal instincts.

Let’s dive into the world of cats and uncover the mystery behind their sometimes baffling behaviors.

Key Takeaways

  • Mother cats may attack their older kittens to enforce territory boundaries and teach them survival skills.
  • Limited food and shelter resources can lead to aggression from mother cats toward their older offspring.
  • Hormonal changes, stress, illness, and injury can also contribute to maternal aggression in cats.

Understanding Cat Behavior

Cat behavior can sometimes be a complex subject to unravel due to their tendencies to portray moods and responses differently than humans. It’s essential to realize that cats, even after years of domestication, still retain many of their ancestral instincts for survival in the animal world.

Regarding mother cats and their older kittens specifically, these instincts oftentimes guide how they interact with each other.

In a typical scenario, the mother cat uses aggression as a form of discipline to teach her kittens about establishing territory and social order in the cat community. She does this not out of cruelty but out of necessity.

This is where behavioral cues such as hissing or swatting come into play; these are methods used by mom cats to instruct their kittens on boundaries within the home. Furthermore, should a mother cat become pregnant again while still having older offspring around, her protective instincts might trigger an aggressive response towards those older kittens.

Reasons Why Mother Cats May Attack Their Older Kittens

Mother cats may attack their older kittens for several reasons, including forcing the kitten to build its territory, limited food and shelter resources, establishing dominance, stress and anxiety, illness or injury, and hormonal changes.

Enforcing the Kitten to Build Its Territory

The mother cat’s aggression is a significant part of the kitten stepping into adulthood. Training kittens became crucial during this period, with the queen establishing her dominance and teaching them survival skills based on cat territorial behavior, particularly in terms of territory marking.

The feline world operates on living territories—each kitten learns to recognize their boundaries and adhere to them earnestly.

As they grow older, maternal instincts prompt the mother cat to force her kittens towards independence by employing some tough love. At around 14 weeks old, she initiates an aggressive temperament as a way of passing down discipline and self-reliant abilities for their survival outside their designated nesting spot.

She uses hissing and biting to underline that lack of space will not be tolerated in her territory while also ensuring each sibling knows who is in charge inside these borders. This hostility may seem harsh but keep in mind it’s primarily about equipping kittens for an independent life beyond the safe confines of home.

Limited Food and Shelter Resources

Mother cats may perceive a threat to their survival due to limited food and shelter resources. This sense of scarcity often leads to aggressive maternal behavior towards older kittens.

The mother cat prioritizes her own survival, or that of her new litter, leading her to assert dominance over the older offspring. Stress stemming from this lack of resources can also cause hormonal imbalances in the mom cat, exacerbating problematic behaviors.

Hunger serves as another trigger for aggression; the mother cat seeks peace while eating and will act out if she encounters interruptions from her kittens. In some instances, a dearth of food and shelter forces the mother cat into rejecting her older kittens, which should be capable enough now to find their own resources, highlighting a fundamental aspect of feline survival skills – independence when necessary.

Establishing Dominance

Mother cats may attack their older kittens as a way of establishing dominance. This is a natural part of the weaning process and helps them prepare for life outside the nest. By asserting their authority, mother cats teach their kittens important survival skills like fighting and hunting.

It’s important to understand that this behavior comes from a place of love and wanting to ensure the safety and independence of their offspring. So, if you witness a mother cat displaying aggressive behavior towards her older kittens, it’s likely because she is trying to establish her dominance and help them grow into strong, capable cats.

Stress and Anxiety

Stress and anxiety can have a significant impact on a mother cat’s behavior toward her older kittens. When a cat is feeling stressed or anxious, it can lead to increased aggression and hostility.

This can manifest as the mother cat attacking her older kittens, even if she has previously shown nurturing behavior towards them. Factors such as changes in the environmentnew additions to the family, or disruptions to routine can all contribute to stress and anxiety in cats.

It’s important for cat owners to be aware of these potential triggers and take steps to create a calm and stable environment for their feline companions.

Illness or Injury

Illness or injury can play a significant role in causing a mother cat to attack her older kittens. When a mother senses that one of her kittens is sick or injured, she may see them as vulnerable and believe their chances of survival are low.

In an effort to protect the overall well-being of the litter, she may exhibit aggressive behavior toward the affected kitten. This instinctual response is driven by the mother’s natural drive for survival and to ensure the strongest members of her offspring survive.

It’s important to recognize signs of illness or injury in kittens early on and seek veterinary care if needed to prevent potential aggression from the mother cat.

Additionally, hormonal changes resulting from illness or injury can also contribute to maternal behavior problems in cats. Hormonal imbalances can affect a cat’s mood and temperament, leading to increased stress levels and decreased tolerance towards her kittens.

If a mother cat is experiencing discomfort or pain due to illness or injury, it can further exacerbate any aggressive tendencies she may have towards her older kittens. Providing appropriate medical attention and addressing any underlying health issues in both the mother cat and her offspring can help mitigate these behaviors and promote a more harmonious relationship within the family unit.

Hormonal Changes

Hormonal changes in cats can have a significant impact on their maternal behavior. These changes can lead to aggression towards older kittens, as well as rejection of them altogether.

When a mother cat experiences hormonal imbalances or fluctuations, it can trigger her to become more aggressive and defensive toward her offspring. This aggression may be due to the cat’s instinctual need to establish dominance and protect her territory.

It is important for cat owners to understand these hormonal changes so they can provide the necessary support and intervention to ensure the safety and well-being of both the mother cat and her older kittens.

Signs of Maternal Aggression

  • Growling and hissing
  • Swatting or biting
  • Puffed-up fur and arched back
  • Blocking access to food or nesting spot
  • Stalking and chasing the kittens
  • Frequent yowling or loud vocalizations

Tips To Prevent a Mom Cat from Attacking Their Kittens

  • Provide the mother cat with a separate nesting spot where she can rest and have some alone time away from her kittens.
  • Gradually separate the kittens from their mother for short periods of time to help them become more independent.
  • Socialize the kittens with other cats and humans to help them develop vital social skills.
  • Establish dominance by gently asserting your authority over the mother cat, using positive reinforcement techniques such as treats and praise.
  • Introduce a crate or carrier as a positive association for the mother cat, providing her with a safe space when she needs a break.

How do I stop my older cat from attacking my kitten?

To prevent your older cat from attacking your kitten, there are several steps you can take. First, ensure that each cat has their own separate space with food, water, and a litter box to minimize competition.

Gradually introduce them through scent swapping and supervised interactions to help them become familiar with each other’s presence. Provide plenty of positive reinforcement and rewards when they display calm behavior around each other.

Additionally, consulting with a veterinarian or animal behaviorist may provide further guidance on managing their interactions and ensuring the safety of both cats.

How long does maternal aggression last in cats?

Maternal aggression in cats typically lasts until the kittens are around 14 weeks old. This natural behavior is part of the weaning process, where the mother cat encourages her kittens to become independent.

During this time, the mother cat may exhibit protective and territorial behaviors as she establishes boundaries with her growing kittens. It’s important for owners to understand that maternal aggression is a normal phase and will naturally decrease as the kittens mature.

How do I know if my cat is hurting my kitten?

If you suspect that your cat is hurting your kitten, there are some signs to look out for. Watch for any aggressive behavior from the mother cat towards the kittens, such as hissing or growling.

Pay attention to how the mother interacts with her kittens – if she seems overly rough or doesn’t allow them to nurse or play, it could be a sign of harm. Keep an eye on the kittens for any injuries or unusual behavior, as this may indicate that they have been hurt.

It’s important to consult with a veterinarian if you have concerns about the safety and well-being of your kitten.


In conclusion, mother cats may attack their older kittens for a variety of reasons. These include enforcing territorial boundarieslimited resourcesestablishing dominancestress and anxietyillness or injury, and hormonal changes.

It is important for cat owners to understand these behaviors and take steps to prevent aggression through proper training and creating a safe environment for both the mother cat and her kittens.
