Why Does My Cat Drool – Should I Be Concerned?

Excessive drooling is considered normal in some pets. But in cats, excessive drooling is associated with numerous illnesses and complications. So I did my research, and this is what I found out.

Why does my cat drool – should I be concerned? Unlike some dog breeds, cats are not big droolers. In fact, most cats don’t drool when offered something tasty. Cats drool when happy and content, which is actually normal. However, excessive drooling can be a sign of a serious health complication, including organ infections.

Nevertheless, this doesn’t necessarily mean that excessive drooling can be a sign of severe physical health complications. Drooling can also be a sign of stress or motion sickness. In this article, we’ll focus on what causes drooling, how to stop excessive drooling, and the effects of cat drool on human beings. But before we get into that, we need to find out if cat drooling is normal.

Is It Normal For Cats To Drool?

Why Is My Cat Drooling When I Pet Her?

Drooling is a sign of contentment and relaxation that can be traced back to when your cat was young.

Therefore, it is normal for cats to drool when they are purring or kneading. Kittens knead their paws on their mother’s breasts when nursing to stimulate the release of milk.

When they mature, the feeling of contentment when you pet it leads to purring. And this stimulates drooling since purring is related to nursing. Your cat purrs when you bond with it, which means it drools when it is happy.

Some of the main causes of drooling in cats include:


Some cats drool when they are asleep and that is because they are relaxed. Remember, cats drool when they are extremely relaxed and happy. In fact, this type of drooling is an indication of an extremely happy cat.

Old Age

A little drooling is normal, especially when your senior cat is relaxed and happy. However, old age comes with numerous health issues like organ and dental diseases which can cause abnormal drooling. So, if your senior cat drools excessively you should take it to the vet.

Cats can become stressed during a loud event, vet visit, or car rides and start drooling temporarily. If your feline pal becomes excessively stressed regularly, you should consult your vet. However, if stress and drooling are short-lived, then you shouldn’t worry too much about it.

Ingestion Of A Small Amount Of Flea Medication

Appropriate application of flea medication on your cat’s body can help you control a flea infestation. However, these medications can be toxic, and if your cat ingests a small amount of the flea medication, it will start drooling excessively. If that happens, make sure you take it to the vet immediately as any form of poisoning can cause rapid death.


When the temperature is extremely high, your cat can become lethargic and start drooling. So, make sure you take it to a cool place as soon as you notice these signs. After all, cats don’t tolerate heat any better than us, despite their reputation as a desert creature.
