Why do Cats Attack Pregnant Woman: Causes & Solutions

why do cats attack pregnant woman

Expecting mothers often face a puzzling issue: their beloved cats suddenly attack them. The primary reason for this behavior is the change in pheromones and scent due to hormonal shifts during pregnancy, making cats feel uneasy or threatened.

This article will delve deeper into this issue, discussing its science, debunking misconceptions, and providing practical solutions to ensure a harmonious environment for the mother-to-be and her feline companion.

With this knowledge, you can maintain a loving bond with your cat throughout pregnancy.

The Science Behind Cats and Pregnancy

Cats and Pheromones

Cats possess a remarkable sense of smell, which allows them to detect pheromones. Pregnant women experience hormonal changes, including the release of different pheromones. These new scents can cause confusion and agitation in cats, leading to aggressive behavior.

Hormonal Changes

As a woman’s hormones change during pregnancy, her scent may also vary. Cats can detect these changes and may become uneasy or aggressive.

Cats’ Heightened Senses

Increased Sensitivity to Scents

Cats have a keen sense of smell that is 14 times stronger than humans. They can detect even the slightest environmental changes, including new pregnancy-associated scents.

Ability to Sense Emotions

Cats are also highly intuitive and can sense changes in their owner’s emotions. Pregnant women may experience mood swings, stress, or anxiety, which their cats may pick up on, causing them to become agitated or aggressive.

Protective Instincts

Territorial Behavior

Cats are territorial by nature and may perceive pregnancy-related changes as a threat to their domain. This can result in aggressive behavior towards the pregnant woman.


Cats may feel jealous or threatened by the attention their pregnant owner receives, leading to aggressive behavior.

Misconceptions About Cats and Pregnant Women

Old Wives’ Tales

Many myths and misconceptions about cats and pregnant women include the belief that cats can “steal the baby’s breath.” Such tales are unfounded and should not be taken seriously.

Fear of Toxoplasmosis

Toxoplasmosis is a concern for pregnant women, but it is essential to understand that the risk of contracting the infection is low if proper precautions are taken. It is not a reason for cats to become aggressive toward pregnant women.

Understanding Cats’ Aggressive Behavior

Reason for Aggression Solution
Pheromones and Hormonal Changes Establish boundaries and provide a designated space for your cat
Heightened Senses Offer mental stimulation through toys and activities
Protective Instincts (Territorial Behavior, Jealousy) Reinforce positive behavior with rewards
Play Aggression Engage your cat in regular playtime
Redirected Aggression Identify and address the source of frustration
Fear-Induced Aggression Ensure a safe environment and seek professional help if needed

Play Aggression

Cats may attack pregnant women due to play aggression, which occurs when cats have pent-up energy and need an outlet for their natural hunting instincts.

Redirected Aggression

Cats may exhibit redirected aggression when they cannot control their frustration or agitation. For example, if a cat sees a bird outside but cannot reach it, it may redirect its aggression toward its pregnant owner.

Fear-Induced Aggression

Cats may become aggressive if fearful or feel threatened by the changes they observe in their pregnant owner. This is a defense mechanism to protect themselves from perceived danger.

Preventing Cat Attacks on Pregnant Women

Establishing Boundaries

Establishing clear boundaries with your cat during pregnancy is crucial. Teach your cat that certain areas, such as the nursery or your lap, are off-limits to help reduce their aggression.

Providing Mental Stimulation

Ensure your cat has plenty of opportunities for mental stimulation, such as interactive toys or puzzle feeders. This can help prevent boredom and reduce aggressive behavior.

Positive Reinforcement

Reward your cat with praise, treats, or playtime when they exhibit positive behavior around the pregnant woman. This helps reinforce their good behavior and reduces the chances of aggression.

Dealing with an Aggressive Cat

Seek Professional Help

If your cat continues to exhibit aggressive behavior towards the pregnant woman despite your efforts, consider seeking help from a professional, such as a veterinarian or a certified animal behaviorist.


Medication is sometimes necessary to help manage your cat’s aggressive behavior. Speak with your veterinarian to determine if this is the best action for your situation.

Ensuring a Safe Environment for Pregnant Women and Cats

Cat-Proofing Your Home

To ensure a safe environment for the pregnant woman and the cat, cat-proof your home. Secure potentially dangerous items and provide designated spaces for your cat to explore and play.

Providing a Designated Space for Your Cat

Create a designated space for your cat with a comfortable bed, toys, and a scratching post. This will give your cat a safe space to retreat when they feel overwhelmed by the changes in their environment.


While it is common for cats to attack pregnant women, understanding the reasons behind this behavior can help you take the necessary steps to prevent aggression and ensure a harmonious relationship between your feline companion and the expecting mother.

Addressing the underlying issues and creating a safe environment for both can help maintain a loving bond throughout the pregnancy and beyond.
