Causes of Cat Drooling

Cat drooling can be caused by a variety of things, including excitement, contentment, nausea, dental problems, heat exhaustion, and diseases or infections. When cats are excited, they may drool in anticipation of something they are looking forward to, such as a treat or a petting session.

Cats may also drool when they are content, such as when they are being petted or when they are sleeping. Nausea can also cause cats to drool as a sign of discomfort. Dental problems, such as gum disease, can cause cats to have painful mouth ulcers or abscesses, leading to drooling.

Heat exhaustion is another common cause of drooling in cats, as their bodies become overheated and unable to regulate their temperature. Finally, certain diseases or infections can also cause cats to drool, such as rabies, feline leukemia, or distemper.

  • Ingestion of a toxic substance
  • Infection

  • Neurological disorders
  • Dental problems

Prevention of Cat Drooling

To prevent cat drool, it is important to keep your cat’s mouth healthy. Regular brushing of your cat’s teeth with a pet-safe toothpaste is essential to reduce plaque buildup which can lead to drooling. You should also ensure your cat is eating a high quality, balanced diet. Keep your cat’s diet varied and interesting by adding supplements or treats.

Regular vet checkups are also recommended to make sure your cat’s health is up to date and any potential underlying issues can be addressed. Finally, keep your cat stress-free by providing plenty of toys and interactive playtime.

Identification and Signs of Unhealthy Cat Drooling

Cat drooling is usually a sign of something minor, such as being content or excited, however, excessive or constant drooling can indicate an underlying medical condition. Common signs of unhealthy drooling include excessive drooling accompanied by a refusal to eat, lethargy, depression, weight loss, mouth pain, and foaming at the mouth.

If you notice any of these signs, you should take your cat to the vet for a full physical exam. In addition to physical exams, your vet may also recommend blood tests and imaging to help identify any underlying medical conditions causing the drooling.

Amount, Texture, and Color

Cat drooling can vary in amount, texture, and color. Generally, the amount of drool produced by cats is minimal, but can increase when they are feeling content or relaxed. The texture of cat drool is usually thin and watery, but can become thicker and more viscous when cats are feeling ill or stressed. The color of cat drool can range from clear to yellow or green, depending on the cat’s diet and health. If the drool produces an unusual odor or if the color is darker than usual, it may be a sign of illness and it is best to see a veterinarian for a proper diagnosis.


Cat drooling is a very common behavior in cats. It is normal for cats to drool when they are relaxed and content, as a way of expressing happiness and contentment. It can also be a sign of various medical conditions, so it is important to take your cat to the vet if you notice it drooling excessively.
