Why does a cat drool when stroked? - briefly
A cat may drool when stroked due to a heightened sense of pleasure or relaxation. This response is similar to the "flehmen reaction" in big cats, where they open their mouths and curl their lips upwards to enhance their olfactory experience.
Why does a cat drool when stroked? - in detail
Cats are known for their unique behaviors and reactions, one of which is drooling when stroked or petted. This phenomenon can be attributed to several factors that influence a cat's physiological and psychological responses.
Firstly, it is important to understand that cats have scent glands located in various parts of their bodies, including their cheeks and chin. When these areas are stimulated by petting or stroking, the scent glands release pheromones. These chemical signals play a crucial role in marking territory, communicating with other cats, and expressing emotions. Drooling is often accompanied by head rubbing, which further enhances the distribution of these pheromones.
Moreover, drooling can be a sign of contentment and relaxation for many cats. When stroked gently in areas they enjoy, such as behind the ears or under the chin, cats may begin to salivate as part of their natural response to pleasure and comfort. This is similar to the way humans might salivate when anticipating a delicious meal or experiencing a pleasant sensation.
Another factor contributing to drooling is the cat's unique anatomy. Cats have barbs on their tongues that act like tiny hooks, helping them to groom themselves and remove loose hair. These barbs can also stimulate saliva production when the tongue is used during grooming or licking behaviors. When a cat is stroked in areas where they would normally groom themselves, such as the head or neck, it can trigger this same response.
In some cases, excessive drooling might indicate an underlying health issue. Conditions such as dental problems, respiratory infections, or even certain types of cancer can cause a cat to drool more than usual. If a cat's drooling behavior seems abnormal or is accompanied by other symptoms like lethargy, loss of appetite, or difficulty breathing, it is advisable to consult with a veterinarian for a proper diagnosis and treatment.
In summary, a cat's tendency to drool when stroked is largely driven by natural physiological processes involving scent glands and pheromones, as well as the cat's unique anatomy. While it is often a sign of contentment and relaxation, pet owners should be aware of any changes in their cat's drooling behavior that could indicate potential health concerns.
