Do Cats Drool When They Sleep?

Have you ever wondered why your cat wakes up from a nap with a wet spot on its chin? Cats are known for their grooming habits, but do they drool when they sleep? In this article, we will explore the fascinating world of feline behavior and uncover the truth behind this intriguing question. So, let’s dive in and find out if cats really drool when they sleep!

Why Do Cats Drool?

Cats, like humans, have salivary glands that produce saliva. While some cats may drool more than others, drooling is a normal physiological response in cats. There are several reasons why cats may drool, and it is important to understand the underlying cause to determine if it is a cause for concern or simply a natural behavior.

One common reason why cats drool is excitement or anticipation. You may notice your cat drooling when they are about to be fed or when they are playing with a favorite toy. This type of drooling is usually short-lived and not a cause for concern.

Cats may also drool when they are purring. Purring is a sign of contentment and relaxation, and some cats may become so relaxed that they start to drool. This is often seen in cats who are receiving gentle pets and attention.

In some cases, cats may drool excessively due to dental problems, such as gum disease or tooth decay. If you notice that your cat is drooling more than usual, it is important to have their oral health checked by a veterinarian to rule out any underlying dental issues.

Do Cats Drool When They Sleep?

Now let’s address the main question at hand – do cats drool when they sleep? The answer is yes, cats can drool when they sleep, but it is not a common occurrence. Cats may drool during sleep if they are in a deep state of relaxation or if they are dreaming. Just like humans, cats can experience vivid dreams, and during these dreams, they may exhibit behaviors such as twitching, kneading, and yes, drooling.

While it may be surprising to see your cat drooling during sleep, it is usually nothing to be concerned about. However, if you notice any other unusual symptoms accompanying the drooling, such as difficulty breathing or excessive snoring, it is best to consult with a veterinarian to rule out any underlying health issues.

How to Prevent Excessive Drooling in Cats

If you find that your cat is drooling excessively, there are a few steps you can take to help prevent it:

  • Maintain good oral hygiene: Regular brushing of your cat’s teeth and routine dental check-ups can help prevent dental issues that may lead to excessive drooling.
  • Provide a stress-free environment: Cats can become anxious or stressed, which may trigger excessive drooling. Creating a calm and comfortable environment for your cat can help reduce stress-related drooling.
  • Monitor your cat’s diet: Certain foods or treats may cause an allergic reaction in cats, leading to excessive drooling. If you suspect a particular food is causing the issue, consult with your veterinarian to determine the best diet for your cat.


In conclusion, cats can drool when they sleep, but it is not a common occurrence. Drooling in cats can be a natural response to excitement, relaxation, or dreams. However, if you notice excessive or persistent drooling, it is important to consult with a veterinarian to rule out any underlying health issues. By maintaining good oral hygiene, providing a stress-free environment, and monitoring your cat’s diet, you can help prevent excessive drooling in your feline companion. Remember, a little drool is just a small part of the wonderful world of cats!
