Cats are fascinating creatures that have been domesticated for thousands of years. They are known for their independent nature and unique behaviors that often leave their owners wondering what they mean. One such behavior is when a cat opens her mouth while being petted, especially on the head. While this behavior may seem strange, there are several reasons why cats do it.
To understand why cats open their mouths when petted, it’s important to first look at the anatomy of a cat’s mouth. Cats have a unique organ in their mouth called the vomeronasal organ, also known as the Jacobson’s organ. This organ helps cats to detect pheromones, which are chemical signals that other cats produce. When a cat opens her mouth while being petted, she may be using this organ to get a better sense of her surroundings.
Cat body language is also an important factor to consider when trying to understand this behavior. When a cat is relaxed and content, she may open her mouth and close her eyes while being petted. This is a positive response and is a sign that she is enjoying the interaction. On the other hand, if a cat opens her mouth and flattens her ears or lashes her tail, it may be a sign that she is feeling threatened or uncomfortable.

Anatomy of a Cat’s Mouth
Understanding the anatomy of a cat’s mouth can help us better understand why they open their mouths when we pet them. Here are some key features of a cat’s mouth:
Teeth
Cats have 30 teeth, including incisors, canines, premolars, and molars. Their teeth are sharp and pointed, which is why they are known for their ability to bite and scratch. Their teeth are also designed for tearing and shredding meat, as cats are obligate carnivores.
Cats have two sets of teeth in their lifetime. They have deciduous (baby) teeth, which are replaced by permanent teeth when they are around 4-6 months old.
Tongue
A cat’s tongue is covered in tiny, backward-facing spines called papillae. These papillae help cats groom themselves by removing loose fur and dirt from their coat. They also help cats scrape meat off bones when they are eating.
Cats also use their tongues to drink water. They lap up water by curling their tongue backwards and using it to scoop up the liquid. This action creates a column of water that they then swallow.
Overall, a cat’s mouth is designed for hunting, eating, and grooming. The sharp teeth and rough tongue are essential tools for their survival in the wild. When we pet our cats, we may be inadvertently stimulating their natural instincts and causing them to open their mouths in response.
Cat Body Language
Cats use their body language to communicate with their owners. Understanding their non-verbal cues can help you better understand your cat’s mood and behavior. Here are two important body language cues to look out for:
Mouth Openness
When a cat opens her mouth, it can mean different things depending on the context. If your cat is panting or breathing heavily with her mouth open, it could indicate that she is overheated or stressed. In this case, it’s important to provide a cooler and more comfortable environment for your cat.
However, if your cat opens her mouth while you’re petting her head, it’s likely a sign of relaxation and contentment. Cats often close their eyes and open their mouths when they’re enjoying being petted. This positive response encourages you to continue petting her and helps to improve the bond between you and your cat.
Ear Position
Cats use their ears to communicate their mood and intentions. Here are some common ear positions and what they might mean:
- Forward and Up: Your cat is alert and interested in something.
- Slightly Forward: Your cat is relaxed and content.
- Flat Against the Head: Your cat is scared or anxious.
- Rotated Sideways or Back: Your cat is feeling aggressive or defensive.
By paying attention to your cat’s ear position, you can get a better sense of how she’s feeling and respond accordingly. If her ears are flat against her head, for example, it’s best to give her some space and let her calm down.
Understanding your cat’s body language can help you build a stronger bond with your feline friend. By paying attention to her non-verbal cues, you can better understand her needs and provide her with the care and attention she deserves.
Possible Reasons for Mouth Opening
When a cat opens its mouth while being petted on the head, it can be a sign of different things. Below are some possible reasons why your cat might be opening its mouth.
Pleasure
One possible reason why your cat opens its mouth when you pet her head is because she is experiencing pleasure. This is known as the flehmen response, and it is a way for cats to analyze scents better. Their vomeronasal organ, which helps detect pheromones and other scents, is located at the roof of their mouth. So, when your cat opens her mouth, she is allowing more air to flow over this organ, which enhances her ability to analyze the scent.
Displeasure
On the other hand, if your cat is opening her mouth while being petted and appears to be uncomfortable, it could be a sign of displeasure. Some cats might not enjoy being petted on the head, and the mouth opening could be a way for them to communicate their discomfort. If your cat is also hissing, growling, or swatting at you, it is best to stop petting her and give her some space.
Medical Issues
In some cases, cats might open their mouths due to medical issues. For example, if your cat is panting heavily with her mouth open, it could be a sign of respiratory distress or overheating. It is important to monitor your cat’s behavior and seek veterinary care if you notice any concerning symptoms.
In conclusion, cats can open their mouths for various reasons, and it is important to pay attention to their body language and behavior to understand what they are trying to communicate. If you are unsure why your cat is opening her mouth, it is always best to consult with a veterinarian to rule out any underlying medical issues.
