Common Causes of Drooling in Cats

While occasional drooling is normal for cats, excessive drooling can be a cause for concern. It’s essential to identify the underlying cause of the drooling to address any potential health issues. In this post, we will discuss some of the common causes of drooling in cats and what you can do to help your furry friend feel better.

Dental problems are one of the most common reasons for drooling in cats. Tartar buildup, gum disease, broken teeth, or oral tumors can all lead to pain and discomfort in your cat’s mouth, causing excessive drooling. Regular check-ups with your vet and providing dental treats and toys can help prevent dental issues that may cause excessive drooling.

Nausea or gastrointestinal problems are another possible reason for excessive drooling in cats. If your cat has eaten something that doesn’t agree with their stomach or has an underlying gastrointestinal issue, it can cause nausea and excessive drooling. If you notice other concerning symptoms such as vomiting or diarrhea, seek veterinary attention promptly.

Certain medications can also cause your cat to drool excessively when they’re resting. If your cat has recently started taking medication, check the side effects to see if drooling is listed as one of them. Your vet may be able to adjust the dosage or switch to a different medication if necessary.

Some breeds of cats, such as Persians, are known to produce more saliva than others, which can lead to excessive drooling. While this may be normal for certain breeds, it’s still important to monitor your cat’s behavior and look out for any other concerning symptoms.

Lastly, stress and anxiety can also cause excessive drooling in cats. If your cat feels uncomfortable or threatened in their environment, they may exhibit physical responses such as excessive drooling. Providing a comfortable and safe environment for your cat can help reduce stress levels, and if necessary, your vet may recommend behavioral therapy or medication to help alleviate anxiety.

Dental Issues

However, it can be concerning to notice them drooling excessively in this state. While occasional drooling is normal, excessive drooling could indicate an underlying health issue, such as dental problems. As an expert in this area, I’m here to shed light on how dental issues can cause cats to drool and what you can do to prevent it.

Cats are susceptible to dental issues such as gum disease, tooth decay, and oral cancer. When they experience dental pain or discomfort, they may drool excessively while resting. This happens because the pain increases saliva production and the cat may not swallow it as frequently as they should.

Periodontal disease is one of the most common dental issues that causes drooling in cats. It occurs when plaque and tartar build up on their teeth, leading to inflammation and infection in their gums. If left untreated, it can cause tooth loss and other severe health problems.

To prevent dental issues in cats, it’s important to provide them with regular dental care. This includes brushing their teeth regularly with cat-friendly toothpaste, providing them with dental chews and toys, and taking them for regular check-ups with a veterinarian.

If you suspect that your cat is experiencing dental problems, it’s essential to take them to a vet for an evaluation as soon as possible. Your vet can perform a thorough dental exam and recommend appropriate treatment options to help relieve your cat’s pain and discomfort.

Nausea and Gastrointestinal Problems

Nausea and gastrointestinal problems are some of the most common causes of this behavior, and it’s important to know the underlying issues that could be causing it.

Nausea in cats can be triggered by a range of factors, including motion sickness, medication side effects, or an underlying illness. You may notice other symptoms like vomiting, loss of appetite, and lethargy if your cat is experiencing nausea. Motion sickness is particularly common during car rides, so if your cat drools during or after a car ride, it could be due to motion sickness or medication side effects.

Gastrointestinal problems can also lead to drooling in cats. If your cat has consumed something disagreeable or ingested a toxin, they may experience nausea and drooling. In more severe cases, chronic gastrointestinal issues like inflammatory bowel disease can cause excessive drooling.

It’s vital to take your cat to the vet if you suspect they are experiencing nausea or gastrointestinal problems. A proper diagnosis and treatment plan may include medication, dietary changes, or even surgery in some cases. Addressing these issues promptly can prevent further complications and ensure your cat’s health and well-being.


Don’t worry, this issue is not uncommon and can be caused by certain medications. Some drugs can cause excessive salivation as a side effect, especially when your cat is at rest because they may not be swallowing as often.

Among the most common culprits are medications used to treat pain, such as opioids like morphine or fentanyl. These drugs can depress the central nervous system, leading to excessive drooling. Certain antibiotics and antihistamines can also cause drooling as a side effect.

If you suspect that your cat’s drooling is related to medication, it is crucial to speak with your veterinarian. They can adjust the dosage or prescribe a different medication that does not have this side effect. However, never stop giving your cat any prescribed medication without first consulting with your veterinarian, as this could lead to other health problems.

It is worth noting that medication-induced drooling may resolve on its own as your cat’s body adjusts to the medication. But if the drooling persists or is accompanied by other symptoms such as vomiting or diarrhea, it is important to seek veterinary care right away.

Certain Breeds of Cats

Today, we’re delving into the fascinating world of feline drool. Did you know that certain breeds of cats are more prone to excessive salivation than others? Let’s explore the reasons why.

Firstly, let’s talk about Persians and Himalayans. These cute flat-faced felines are known for their drooling due to a condition called brachycephalic airway syndrome. Basically, their shortened snouts and flat faces make it difficult for them to breathe, leading to drooling as a result. So, if your little ball of fur is leaving a trail of drool everywhere they go, it’s just a part of their unique breed.

But Persians and Himalayans aren’t the only ones who like to leave their mark. Siamese cats are also known to drool, especially when they’re feeling relaxed and content. It’s like they can’t contain their happiness.

However, there are also health conditions that can cause drooling in our furry friends. Issues with dental health like gum disease and tooth decay can lead to discomfort and pain, resulting in excessive salivation. Similarly, cats with kidney disease or liver problems may also experience drooling as a symptom of their illness.

That’s why it’s important for us as cat parents to be aware of our kitty’s breed and any potential health issues that may cause drooling. If you notice excessive drooling accompanied by other symptoms such as vomiting or lethargy, it’s crucial to seek veterinary attention as soon as possible.

Symptoms to Look Out For

When it comes to drooling in cats, excessive drooling is a symptom that should not be ignored. So, what other symptoms should you look out for?

Firstly, if your cat is drooling more than usual, it’s a clear sign that something may be wrong. Keep a watchful eye on your cat and take note of any other concerning symptoms.

Changes in appetite or behavior are also important to pay attention to. If your cat suddenly stops eating or seems lethargic, this could be a sign that something is wrong. Other behavioral changes to look out for include hiding, aggression, or excessive grooming.

Sometimes, drooling can also come with physical symptoms such as vomiting or diarrhea. These symptoms can indicate various health issues, so it’s crucial to take note of any changes in your cat’s overall health and wellbeing.

However, it’s essential to know that drooling can sometimes be completely normal for some cats, depending on their personality and behavior. For example, some cats tend to drool when they are happy or contented while others may drool when they are nervous or anxious. Understanding your cat’s typical behavior can help you determine whether their drooling is cause for concern or not.

To sum up, excessive drooling in cats should not be overlooked and must be monitored closely alongside other potential symptoms such as behavioral changes and physical symptoms like vomiting or diarrhea. While drooling can sometimes be normal for some cats, it’s always better to err on the side of caution and seek veterinary attention if you have concerns about your cat’s health.

Diagnosing the Cause of Excessive Drooling in Cats

Keeping an eye on your feline friend’s behavior and physical symptoms is crucial, especially when it comes to excessive drooling. While some cats may drool due to happiness or anxiety, excessive drooling can also be a sign of an underlying health issue that requires veterinary attention.

The first step in diagnosing the cause of excessive drooling is a visit to the vet for a comprehensive physical examination. During this exam, the vet will check your cat’s mouth, throat, and tonsils for any signs of injury or infection. Gum disease, oral tumors, or foreign objects stuck in the teeth or gums are all possible culprits. If nothing obvious is found, further tests may be performed, such as blood work, X-rays, or an ultrasound to uncover any internal health issues that may be causing the drooling.

It’s important to note that stress or anxiety can also cause excessive drooling in cats. Changes in their environment or routine can often be a source of anxiety for cats. Comfortable and consistent living arrangements can help alleviate stress and reduce drooling.

Treatment for Excessive Drooling in Cats

Although occasional drooling is normal, if you notice your cat drooling excessively, it could be indicative of an underlying health issue that requires immediate veterinary attention.

The treatment for excessive drooling in cats varies depending on the root cause. If your cat’s excessive drooling is due to dental issues like gum disease or tooth decay, a visit to the veterinarian may be necessary to address the problem. In some cases, teeth may need to be extracted or cleaned to alleviate the drooling and prevent further complications.

If the drooling is caused by a respiratory infection, medication may be prescribed to treat the infection and reduce inflammation in the respiratory tract. In severe cases, oxygen therapy may be necessary to help your cat breathe easier and reduce excessive drooling.

Foreign objects lodged in the mouth or throat can also cause excessive drooling. In such cases, immediate removal of the object is necessary to prevent further complications. A veterinarian can use specialized tools to safely remove the object.

Motion sickness or nausea can also lead to excessive drooling in cats. Anti-nausea medication may be prescribed to alleviate symptoms and reduce drooling. Additionally, natural remedies such as ginger or peppermint can help settle their stomachs and reduce nausea.

In rare cases, excessive drooling may be a side effect of certain medications. If this is suspected, it’s imperative to speak with a veterinarian about alternative medication options or adjusting the dosage.

Prevention of Excessive Drooling in Cats

Excessive drooling in cats can be a sign of underlying health issues that require immediate attention. Fortunately, by following some simple preventative measures, you can help prevent excessive drooling and maintain your cat’s overall health and hygiene.

The first step in preventing excessive drooling is to ensure that your cat maintains good oral hygiene. Brushing your cat’s teeth and gums regularly can help prevent dental issues that could cause excessive drooling. Additionally, providing your cat with dental chews or toys can promote oral health and reduce the chances of drooling.

Stress or anxiety could also contribute to excessive drooling. A stressed-out cat may drool more frequently than a relaxed one. To prevent this, make sure your cat has a safe and comfortable environment with plenty of toys and hiding places.

Medical conditions such as dental problems, infections, or gastrointestinal issues can also cause excessive drooling. Regular check-ups with your vet can detect any underlying medical issues promptly and address them accordingly. Your vet can also help you create an effective plan to manage these conditions and reduce the chances of excessive drooling.

Lastly, certain medications or toxins can also cause excessive drooling in cats. Be sure to keep all medications and household toxins out of reach of your cat, and consult with your vet before administering any new medication.


In conclusion, cats drool for a variety of reasons, and while it’s not uncommon, excessive drooling can be a sign of an underlying health issue. Dental problems, motion sickness, medication side effects, or simply relaxation can all contribute to your cat’s drooling habits. As a responsible cat owner, it’s crucial to monitor your feline friend closely and take note of any changes in behavior or physical symptoms.

If you notice your cat drooling excessively alongside other concerning symptoms such as vomiting or diarrhea, don’t hesitate to seek veterinary attention promptly. Your vet can help identify the root cause of the drooling and recommend appropriate treatment.

To prevent excessive drooling in cats, providing regular dental care is essential. Creating a comfortable environment for your cat and keeping all medications and household toxins out of reach are also good preventative measures. Regular check-ups with your vet can detect any underlying medical issues early on and address them accordingly.

In summary, understanding the common causes behind excessive drooling in cats is vital for maintaining their health and wellbeing.
