Why Is My Cat Drooling All The Time?

Cats are known for their meticulous grooming habits, making any sign of unusual behavior, such as excessive drooling, particularly concerning for cat owners. While it’s normal for cats to drool occasionally, especially when they’re relaxed or content, excessive or persistent drooling can indicate an underlying issue that needs attention.

There are many possible reasons for your cat’s drooling and is something that should be addressed if the drooling becomes excessive.

What Are The Normal Causes of Cat Drooling?

There are situations where drooling in cats is entirely normal and not a cause for alarm. For instance, some cats drool when they are purring and feeling extremely relaxed. This is often a sign of contentment, similar to when they knead or nuzzle against you.

Additionally, cats might drool in response to a tasty treat or anticipation of food, especially if it’s something particularly aromatic or appealing to them (not that different from us humans!)

However, even in these cases, the drooling is usually mild and temporary.  If you notice that your cat’s drooling persists beyond these situations, it’s important to figure out the potential causes.

What Are The Potential Causes of Excessive Drooling?

Below are some of the different reasons why your cat might be drooling too much:

1. Dental Issues

Dental problems are one of the most common reasons for excessive drooling in cats. Conditions like periodontal disease, tooth decay, or broken teeth can cause pain and discomfort, leading to drooling. Gingivitis, an inflammation of the gums, can also be a culprit, particularly in older cats or those with poor dental hygiene.

If your cat has bad breath, difficulty eating, or visible swelling around the mouth, these could be signs of dental issues. A veterinarian can perform an oral examination to identify and address the problem. Regular dental checkups and maintaining your cat’s oral hygiene can help prevent these issues.

2. Foreign Objects or Irritants

There are times when a foreign object is lodged in a cat’s mouth or throat which can cause drooling. This could be a piece of food, a string, or even a small toy. Cats are also known to chew on plants, some of which can be toxic or irritating to their mouths, leading to excessive salivation.

 If your cat is pawing at his or her mouth, gagging, or refusing to eat, try to open their mouth carefully if it’s safe to do so to see if you can identify the source. If you can’t find the issue or if the object is lodged deep, a trip to the vet is necessary.

3. Nausea or Motion Sickness

Cats can experience nausea or motion sickness which may result in drooling. This might happen during car rides or if they’ve eaten something that doesn’t agree with them. Other signs of nausea include lip licking, a lack of appetite, or vomiting.

If you suspect motion sickness, consider speaking with your vet about possible solutions, such as using a pet-safe anti-nausea medication before travel. For nausea unrelated to motion, it’s important to determine the cause, as it could be linked to a gastrointestinal issue or toxin ingestion.

4. Exposure to Toxins

Cats are curious creatures and may come into contact with toxic substances that can cause drooling. Common household toxins include cleaning products, insecticides, and certain human medications. Some plants, such as lilies and philodendrons, are also dangerous to cats.

If you suspect poisoning or exposure to toxin, watch for other symptoms like vomiting, lethargy, or tremors. If you suspect your cat has ingested any toxin, you need to go the vet immediately, as ingesting toxins can quickly become life-threatening.

5. Respiratory Infections

Upper respiratory infections (URIs) in cats can lead to excessive drooling, especially if the infection causes mouth ulcers or difficulty swallowing. URIs are often accompanied by other symptoms, such as sneezing, nasal discharge, and fever.

Kittens and cats with weakened immune systems are particularly vulnerable to respiratory infections. If your cat shows these signs, a veterinarian can provide treatment, which might include antibiotics or supportive care.

6. Stress and Anxiety

Cats are sensitive pets, and any stress or anxiety can manifest itself in physical symptoms like drooling. Changes in your cat’s environment, new pets, or loud noises can trigger stress. If your cat’s drooling coincides with behavioral changes, such as hiding or aggression, they may be experiencing anxiety.

Creating a calm and secure environment for your cat can help reduce stress-related drooling. Products like pheromone diffusers or sprays may also provide relief.

7. Oral Cancer or Tumors

Though less common, oral cancer or tumors in the mouth can cause excessive drooling. Other symptoms may include facial swelling, weight loss, or blood in the saliva. Early detection is critical for successful treatment and it’s essential to consult your vet if you notice any of these signs.

What You Should Do If Your Cat Is Drooling Excessively?

If your cat’s drooling is sudden, severe, or accompanied by other concerning symptoms, talk to your veterinarian immediately. It can be helpful to note when the drooling started, any recent changes in their diet or environment, and any other symptoms your cat is displaying.

For mild cases, such as drooling due to relaxation or excitement, no intervention is needed. However, maintaining regular veterinary checkups can help identify potential issues early which will help your cat stay healthy and happy.

Prevention Tips

To minimize the risk of excessive drooling, consider the following preventative measures:

Dental Care:

Brush your cat’s teeth regularly (if you are able to!) and provide dental treats or toys to promote oral health.

Safe Environment:

Keep toxic plants and substances out of your cat’s reach.

Regular Veterinary Checkups:

Schedule routine veterinary visits to catch potential health issues early.

Stress Management:

Create a stable and comforting environment for your cat to reduce anxiety-related drooling.

By understanding the various causes of excessive drooling and taking proactive steps, you can help maintain your feline companion’s health and happiness. While occasional drooling may be harmless, persistent or excessive drooling warrants attention to address any underlying issues.
