Cats are known for their meticulous grooming habits, so when a cat drools excessively but acts normal otherwise, it can be both confusing and concerning. Occasional drooling might not indicate a problem, but persistent or excessive drooling could point to underlying causes that require attention. While your cat may appear content and show no obvious signs of distress, excessive drooling is not something to ignore. If your cat has been drooling excessively but seems fine otherwise, several potential explanations exist. Some are harmless, while others could indicate a developing health concern. Below, we’ll discuss the possible reasons behind this behavior and when you should schedule a veterinary visit.
Normal Causes of Excessive Drooling in Cats
Not all cases of excessive drooling in cats are linked to a medical condition. Some everyday occurrences can lead to increased saliva production without being a cause for alarm.
Contentment and Relaxation
One of the most common reasons a cat drools excessively but acts normal is pure relaxation. Some cats drool when they are particularly happy or content, especially while kneading or being petted. This behavior often starts in kittenhood when nursing and can continue into adulthood as a sign of deep comfort. If your cat only drools in these situations, there is likely nothing to worry about.
Taste Response to Something Unpleasant
Cats have a highly sensitive sense of taste, and exposure to something bitter or unpleasant can trigger excessive drooling. Common triggers include licking or chewing on houseplants, tasting medications, or eating something with an unusual texture. If your cat’s drooling subsides shortly after an encounter with an odd taste, it is probably not a cause for concern.
Teething in Kittens
If you have a young cat, excessive drooling could be linked to teething. Kittens typically begin teething at around three weeks old, with the process continuing until about six months of age. During this time, drooling is common as their new teeth emerge and their gums experience mild discomfort. Providing safe teething toys can help alleviate any irritation.
Dental Issues That Can Cause Excessive Drooling
Even if your cat is acting normal, dental problems could be the culprit behind persistent drooling. Cats are prone to dental conditions that may not immediately cause noticeable discomfort but still impact their oral health.
Periodontal Disease
Periodontal disease develops when plaque and tartar accumulate on the teeth, leading to gum inflammation (gingivitis) and potential tooth decay. While early stages of periodontal disease may not cause obvious pain, excessive drooling can be an early indicator. Over time, if left untreated, this condition can lead to tooth loss and infections.
Tooth Resorption
Tooth resorption is a painful but often unnoticed dental condition in cats, where the tooth structure gradually breaks down. A cat with this condition might continue eating normally but drool more due to discomfort. Since cats instinctively hide pain, changes in drooling patterns can serve as an early warning sign of an underlying issue.
Foreign Objects Stuck in the Mouth
A small object, such as a piece of food, grass, or even a toy fragment, can become lodged between a cat’s teeth or in the gums. This irritation may not cause immediate distress but can trigger increased salivation. Checking your cat’s mouth for foreign objects is challenging, so a veterinary exam may be necessary if drooling persists.
Nausea and Drooling in Cats
While drooling is often associated with oral issues, it can also be linked to mild nausea, even if your cat is still eating and acting normally. Certain conditions can cause temporary nausea without affecting your cat’s overall behavior.
Motion Sickness
Cats can experience motion sickness when traveling in a car, leading to excessive drooling. If your cat only drools when inside a moving vehicle, motion sickness is likely the cause. Providing a comfortable carrier and minimizing stress during car rides can help reduce this reaction.
Hairballs and Gastrointestinal Upset
Cats are prone to hairballs due to their grooming habits. Excessive drooling can sometimes occur when a cat is trying to expel a hairball. While most hairballs pass naturally, excessive drooling without successful expulsion may indicate an obstruction requiring veterinary attention.
Exposure to Toxins and Irritants
If your cat suddenly begins drooling excessively but seems otherwise normal, it’s important to consider potential toxin exposure. Even substances that seem harmless can cause irritation to a cat’s mouth and lead to excessive salivation.
Household Plants and Chemicals
Certain houseplants, such as lilies, philodendrons, and dieffenbachia, can irritate a cat’s mouth if chewed. Additionally, household cleaners, insecticides, and some human foods (like citrus fruits) can cause a drooling reaction. If you suspect your cat has been exposed to something toxic, a veterinary consultation is recommended.
Medications or Topical Treatments
Some flea treatments, especially those not formulated specifically for cats, can cause excessive drooling if licked off the fur. If you recently applied a topical medication, check to ensure it is safe for feline use and monitor for any additional symptoms.
When Is Veterinary Care Necessary for Excessive Drooling?
While some causes of drooling are harmless, others may require veterinary evaluation. If your cat is drooling excessively but acting normal, watch for additional signs that could indicate an underlying issue:
- Drooling that persists for more than a day or two
- Changes in eating habits, such as difficulty chewing or avoiding food
- Foul breath, which may indicate dental disease
- Pawing at the mouth or rubbing the face against objects
- Unusual swelling around the mouth or jaw
If any of these symptoms accompany excessive drooling, scheduling an appointment at World of Animals Veterinary Hospital is the best course of action.
How Your Veterinarian Can Help
A thorough veterinary examination can help determine the underlying cause of your cat’s drooling. Depending on the findings, your veterinarian may perform:
- A dental evaluation to check for gum disease or tooth problems
- An oral examination to look for foreign objects or mouth ulcers
- Diagnostic tests to rule out infections or gastrointestinal issues
- A review of recent dietary changes or potential toxin exposure
If your cat is drooling excessively but acting normal, it’s still important to monitor their behavior and consider a veterinary visit. While some causes are harmless, others could indicate developing health concerns that require professional attention.
