Reasons why your Cat is Drooling

Most cat owners rarely, if ever, see their cat drooling. They aren’t the type of animal to start salivating viciously while imaging chewing on some food. This is why it can be concerning when you suddenly see your cat has started to drool. Drooling can actually be a sign of a serious problem with a cat’s health. However, it can also be something fairly minor.

Reasons why your Cat is Drooling

If you notice your cat has started to drool, it is behavior you need to keep an eye on. It is rarely normal for a cat to drool. This means that when you notice it, you should start to pay attention to how and when they are drooling. Knowing more about the context of your cat’s drooling can help you get to the bottom of why they’re doing it. A cat that has started to drool while sleeping will have a different reason for their behavior than a cat who has started to drool while being played with.

In most cases, drooling is a sign that something is wrong with your cat’s mouth. Investigating why they’re drooling can help you take steps to solve the problem. However, it is important to keep in mind that a vet trip might be your best option. These trained professionals are a lot better at figuring out why a cat has a certain condition going on, so it is often good to trust their judgement. First, you’ve got to look at when your cat is drooling and try to rule out the simpler reasons for this behavior.

Is a Cat Drooling Ever Normal?

A cat drooling is a bit of a strange sight, and you might be concerned that it is instantly a sign of a large health problem for your pet. You can usually work out whether this is the case or not by paying attention to your cat’s behavior. It is rarely normal for a cat to drool, but there are exceptions to this. Cats do drool for perfectly normal and mundane reasons in quite a few cases.

Some cats will drool quite a bit while they’re being petted and having attention given to them. This is strange but it is a behavior that some cats do. This isn’t much of a sign for concern.

In cases like these, the drooling is largely not a cause for concern. The cat is just drooling because this is a strange quirk of their personality. If you’re particularly worried about it, you can bring it up to your vet. But relaxed drooling when being stroked can probably wait until their next check-up.

Nervousness and Stress

Some cats can drool simply because they’re nervous. Stress and nerves will affect animals just as much as it affects humans. In these cases, you might notice your cat begin to drool in a stressful situation, like having a lot of visitors to the house.

The best things to do is to make sure your cat is feeling comfortable. You can also try to help them with their stress. Their stress might be causing their drooling, so addressing the root cause is the most important thing to do. Keep an eye on your cat in the days that follow and make sure their drooling does not return. If it was a one-off occasion, it was likely just caused by stress rather than a larger health problem.


Drooling is considerably more common in kittens than it is in cats. Kittens kneed their mothers to get milk when they’re nursing. When they’re fully grown, they repeat this behavior when they’re relaxed. The milk that they previously got when nursing will cause them to drool. Relaxing can invoke similar feelings of comfort, causing them to drool. This means it isn’t uncommon for a kitten to start to drool when they are just relaxing.

In kittens, drooling isn’t the most worrying thing compared with an adult cat. While you should still mention excessive drooling to your vet, it is much more common in kittens and not necessarily a cause for concern like it is with adults.

Abnormal Drooling in Cats

Those sources of drooling in cats are all fairly normal. This doesn’t mean that they are all that common, but it does mean these sources are less worrying. Abnormal drooling in cats is the type of drooling that isn’t just a general part of behavior. This is drooling that is a cause for concern.

If your cat is drooling and you can’t attribute it to one of those ordinary (if rare) types of drooling, then you have to consider that this might be a sign of a health problem in your cat.

Drooling Because of Oral Problems

Oral hygiene and teeth health is just as important to cats as it is to us. However, pets usually have their teeth and mouths neglected considerably more than humans do. These are some of the main reasons why a cat might drool because of their oral health

  • Tooth Decay – This can lead to a cat drooling at random and likely some pain as well.
  • Mouth Disease – Mouth disease can lead to drooling in your cat’s mouth, this can become a real problem for your cat if it goes on for quite a while.
  • Tartar Build-up – A build-up of tartar on your cat’s teeth can rub against the inside of their lips. This is irritating and will eventually cause them to drool quite a bit. This is one of the easier causes of drooling to take care of.
  • Mouth Sores – A sore in your cat’s mouth can cause drooling in a similar way to tartar build-up. The sore can irritate their lips and cause them to drool.
  • Serious Oral Problems – More serious oral problems like cancer or throat disease can also cause drooling.
  • Injuries – A cut or small injury if your cat’s mouth or throat can cause them to drool.

It can be difficult to tell which of these oral problems is actually the cause of your cat’s drooling. Understandably, this might be worrying since some unclean teeth have the same symptom as oral cancer. This makes it important for you to treat the cause of the drooling as soon as possible.
