Cats are usually meticulous groomers and rarely let anything dribble from their mouths. So, when a cat starts drooling, many owners wonder if something is wrong. While occasional drooling can be harmless, persistent or excessive drooling may signal underlying health concerns. Understanding what causes cats to drool can help determine whether it is normal behavior or a reason to seek veterinary attention.
Is It Normal for Cats to Drool?
Drooling can be expected in some situations, but it often depends on the circumstances. Some cats drool when they are relaxed, happy, or purring. Others may drool due to an underlying issue that requires medical attention. Monitoring the frequency and causes of drooling can help differentiate between harmless and concerning cases.
What Causes Cats to Drool?
Several factors contribute to drooling in cats. Some causes are harmless, while others indicate health problems that require prompt care.
Happiness and Relaxation
- Some cats drool when they are content, especially while kneading or purring.
- A relaxed body posture and a soft expression typically accompany this type of drooling.
- It usually occurs in response to petting or cuddling.
Dental Problems
- Gum disease, tooth decay, or oral infections can cause pain and excessive salivation.
- Drooling may occur if a cat has inflamed gums, loose teeth, or abscesses.
- Bad breath and difficulty eating often accompany dental-related drooling.
Nausea and Digestive Issues
- Motion sickness, stomach upset, or ingesting something toxic can make a cat nauseous.
- Cats experiencing nausea may drool before vomiting.
- Digestive issues may include diarrhea, loss of appetite, or lethargy.
Exposure to Toxins
- Certain plants, household cleaners, and chemicals can be toxic to cats.
- If a cat licks or chews on something harmful, drooling is often an early symptom.
- Other signs of poisoning include vomiting, difficulty breathing, and tremors.
Oral Injuries or Foreign Objects
- Cats that chew on sharp objects or get foreign bodies stuck in their mouths may drool excessively.
- Small bones, grass, or string can become lodged in the mouth, causing discomfort.
- Difficulty chewing or pawing at the mouth often indicates an oral injury.
Upper Respiratory Infections
- Cats with respiratory infections may drool due to mouth ulcers, congestion, or difficulty swallowing.
- Sneezing, nasal discharge, and fever commonly accompany drooling in these cases.
- Viral infections like feline herpes or calicivirus often lead to excessive salivation.
Heatstroke or Overheating
- Excessive drooling can be a sign of heatstroke, especially in hot weather.
- Cats with heat exhaustion may pant, appear weak, or seek cool areas.
- Immediate cooling measures are necessary to prevent severe health issues.
Stress and Anxiety
- Some cats drool when they experience fear or anxiety.
- Stress-related drooling may happen during car rides, vet visits, or unfamiliar environments.
- Signs of stress include hiding, excessive grooming, and changes in appetite.
Medication Side Effects
- Some medications cause excessive salivation as a side effect.
- Bitter-tasting medicines may trigger drooling if they linger in the mouth.
- If drooling persists after medication, consulting a veterinarian is recommended.
Kidney Disease or Liver Problems
- Chronic kidney disease and liver dysfunction can lead to drooling.
- Increased thirst, weight loss, and lethargy are common signs of organ-related issues.
- Routine vet checkups help diagnose and manage these conditions early.
How to Tell If Cat Drooling Is a Problem
While occasional drooling is not always a cause for concern, persistent or excessive drooling warrants closer attention.
- A dental issue may occur if lousy breath, bleeding gums, or difficulty eating accompany drooling.
- When drooling occurs alongside vomiting, diarrhea, or lethargy, a digestive problem or toxin exposure may be responsible.
- Excessive drooling, difficulty breathing, coughing, or mouth ulcers may indicate a respiratory infection or serious illness.
- A vet visit is advisable if a cat suddenly starts drooling excessively without an apparent reason.
