Dec 27, 2024 | Behavior & Training, Cats, New, Pet Ownership

Cats are fascinating creatures, each with their own unique quirks. Some purr loud enough to rival a lawnmower; others “knead” your lap as if preparing dough for biscuits. And then there’s that curious habit of drooling—something you might notice when giving your furry friend a good scratch. But you might find yourself wondering, “Why does my cat drool when I pet him?”

While drooling during petting is often harmless, excessive salivation may also be a sign of health problems. This blog will explore why cats drool, when drooling might indicate an issue, and what steps you can take if your cat’s drooling becomes excessive.

Why Cats Drool When You Pet Them

Drooling isn’t just a dog thing—some cats drool too, and it can actually be a normal response to affection. When you pet your cat, you’re triggering a physiological response tied to their emotions and pleasure, similar to humans smiling when they’re happy.

Emotional Stimuli and Cat Drooling

Cats are highly sensitive creatures, and their emotions can often manifest in physical ways—drooling included. Emotional stimuli, such as excitement, relaxation, or anxiety, can trigger salivation in felines.

For instance, when cats feel particularly happy or comforted during petting, some may drool as a sign of their contentment. This behavior is often a remnant of kittenhood, where kneading and drooling accompanied nursing from their mother.

Nostalgia and Conditioning

Interestingly, some cat behavior experts believe drooling during petting is rooted in kitten behavior. When nursing, kittens can drool in response to suckling and feeding. For some adult cats, these feelings of contentment may translate to drooling even long after they’ve grown out of nursing.

Stress Response

On the other hand, drooling isn’t always linked to positive emotions. Certain cats may drool when they’re feeling overwhelmed, uneasy, or stressed—such as during a car ride or in response to loud noises. Drooling in these situations often accompanies other signs of distress, like hiding, excessive grooming, or poor appetite.

When to Worry About Drooling

While occasional or small amounts of drool aren’t typically a cause for concern, excessive cat drooling could indicate a more serious underlying issue.

Dental Problems in Cats

Drooling in cats can sometimes indicate underlying dental problems. Oral health issues such as gum disease, tooth decay, or mouth ulcers are common culprits behind excessive salivation. Cats suffering from dental pain may drool as they struggle to eat, or they may avoid eating altogether, leading to noticeable changes in appetite and behavior.

Tartar buildup or infections can irritate the gums, causing inflammation and discomfort, which in turn may result in them drooling excessively. Additionally, oral injuries, such as cuts or broken teeth, can provoke similar symptoms.

Regular dental check-ups and cleanings with your veterinarian are crucial for identifying and addressing these problems early, ensuring your cat maintains a comfortable and healthy mouth while avoiding dental disease. If you notice persistent or abnormal drooling, foul breath, or any signs of oral discomfort, consult your veterinarian promptly to rule out dental issues.

Foreign Bodies and Mouth Injuries

Your cat’s inquisitive nature can sometimes lead to trouble. A foreign object like a sewing needle, plant material, or even a piece of a toy can get lodged in their mouth, causing discomfort and drooling. Additionally, mouth injuries like ulcers or cuts from sharp objects can inflame the tissue and lead to saliva overproduction. Monitor for signs like pawing at their face or blood-tinged drool.

Poisonous Substances or Toxin Exposure

Exposure to toxins or poisonous substances may also result in excessive cat drooling. Cats are notorious for chewing on houseplants, but some plants (like lilies or poinsettias) can be harmful if ingested. Cleaning products, certain foods, and medications not meant for cats are also potential dangers. If you suspect toxin exposure, contact your veterinarian immediately.

Viral or Respiratory Conditions

Excessive drooling in cats can also be a symptom of viral or respiratory conditions. Common illnesses such as feline herpesvirus (FHV) or calicivirus can cause oral and nasal irritation, leading to increased salivation.

These infections often result in additional symptoms, including sneezing, nasal discharge, coughing, or even ulcers within the cat’s mouth or throat. Such symptoms can make swallowing uncomfortable and contribute to drooling.

Cats with respiratory conditions may also exhibit a loss of appetite, lethargy, and other signs of distress. Vaccination and regular health check-ups play a vital role in preventing these viruses. If your cat displays drooling alongside respiratory symptoms, seek veterinary care to determine the cause and pursue the appropriate treatment.

Mouth Tumors or Oral Cancer

Mouth tumors or oral cancer can also lead to excessive drooling in cats. These growths may develop on the gums, tongue, cheeks, or other areas of the oral cavity.

They can cause discomfort, inflammation, and difficulty swallowing, which often results in increased salivation. Other signs to be aware of include visible lumps in the mouth, foul breath, bleeding, or difficulty eating.

Malignant tumors, such as squamous cell carcinoma, are among the most common oral cancers in cats and require prompt diagnosis and treatment to improve outcomes. If you notice persistent drooling accompanied by any of these signs, consult your veterinarian immediately.

Early detection is critical in managing oral cancer and providing the best possible care for your cat. Regular oral exams and monitoring for changes in behavior or appetite can help in identifying potential problems early.

Nausea or Motion Sickness

Did you know cats can experience motion sickness? Factors like a car ride or feeling nauseous from an upset stomach can lead to drooling. Motion sickness is often accompanied by other signs, like vomiting, lethargy, or an unwillingness to eat.

How to Address Excessive Drooling

If your cat’s drooling seems out of the ordinary, it’s time to take action. While minor drooling during petting can usually be chalked up to happiness, you should consult a veterinarian if the drooling is excessive or accompanied by symptoms like pain, swelling, or difficulty breathing.

Schedule a Vet Visit

It’s always better to be safe than sorry. Schedule an appointment with your veterinarian to determine the underlying cause of your cat’s drooling. Your vet can check for dental issues, signs of injury, or other medical conditions that might require treatment.

Examine Their Environment

Take a close look at your cat’s surroundings for any potential hazards, such as toxic plants, sharp objects, or unsafe foods that they may have chewed on. Removing these risks can greatly reduce the chance of toxin exposure or injury.

Monitor for Other Signs

Keep an eye out for other symptoms such as poor appetite, weight loss, or difficulty breathing. These could provide clues about the underlying cause of the drooling and assist your vet in diagnosing the issue.

Maintain Regular Dental Care

Dental problems are a common cause of excessive drooling in cats, so prioritize their oral health. Regular dental cleanings, chewable treats that support teeth, and vet-approved dental rinses can go a long way in preventing issues like gum disease or tooth abscesses.

Provide Comfort During Stressful Situations

If drooling occurs in stressful situations, such as during a car ride, focus on calming your cat down. A comfortable carrier, soothing music, or using pheromone sprays can help ease their stress and reduce drooling.
