Understanding Normal Cat Drooling

Cats don’t drool as often as dogs, so seeing saliva around your cat’s mouth can be surprising. While some drooling is perfectly normal, especially in response to specific stimuli, it’s essential to recognize the difference between healthy drooling and potential problems.

Situations When Drooling Is Normal

Your cat might drool slightly in the following situations:

  • Anticipating Food: Some cats may drool when they see or smell their favorite treat. This is a natural response to excitement or hunger.
  • Relaxation or Affection: Cats may drool when they are purring or in a state of deep relaxation, such as during petting sessions.
  • Dental Stimulation: Occasionally, mild drooling occurs when your cat chews on a toy or object.

If your cat’s drooling occurs only in these situations and stops shortly afterward, it’s likely not a cause for concern. However, drooling that is thick, persistent, or excessive warrants further investigation.

Potential Causes of Thick Drooling in Cats

When your cat is drooling thick saliva, it may point to an underlying issue. These range from mild and easily treatable conditions to more serious health problems. Below, we’ve outlined common reasons cats drool thick saliva and what they could mean for your pet.

Dental or Oral Health Problems

Dental issues are one of the leading causes of thick drooling in cats. Conditions such as gingivitis, periodontal disease, or oral ulcers can irritate the mouth, leading to excess saliva production. Some signs of dental issues to take note of include: 

  • Red, inflamed, or bleeding gums
  • Difficulty eating or chewing
  • Bad breath (halitosis)

Thick drooling may also result from an abscessed tooth or foreign object lodged in the mouth. If you suspect a dental issue, schedule a veterinary visit for a thorough examination and professional cleaning.

Nausea and Digestive Upsets

Nausea can trigger thick drooling in cats, just as it does in humans. Digestive problems such as gastritis, hairballs, or ingesting toxic substances can cause your cat to feel queasy and drool excessively. Common triggers of nausea might be eating something they shouldn’t, such as houseplants or spoiled food, a sudden change in diet, or parasites or infections affecting the stomach.

Foreign Objects or Trauma in the Mouth

Cats are naturally curious and may chew on objects they shouldn’t. Items such as strings, small toys, or household items can get stuck in your cat’s mouth or throat, causing irritation and thick drooling. Watch for pawing at the mouth, difficulty swallowing, or visible swelling or bleeding in the mouth. In these cases, avoid trying to remove the object yourself, as this could cause more harm. Instead, contact Minnieville Animal Hospital for immediate assistance.

Medical Conditions Linked to Drooling

Beyond dental and digestive issues, thick drooling can also be a symptom of more complex medical conditions. Let’s explore some of these in greater detail.

Respiratory Infections

Upper respiratory infections (URIs) can affect a cat’s ability to swallow and lead to drooling. These infections are typically caused by viruses, such as feline herpesvirus or calicivirus, but bacterial infections can also play a role. Additional symptoms of URIs include: 

  • Sneezing or nasal discharge
  • Coughing
  • Reduced appetite or lethargy

Toxicity or Poisoning

Ingesting toxic plants, chemicals, or medications can cause thick drooling in cats as their body tries to expel the harmful substance. Common household items like antifreeze, cleaning products, and certain foods (e.g., onions, garlic, or chocolate) are dangerous for cats. If you notice drooling with foam or discoloration, tremors or seizures, and vomiting or diarrhea, your pet may have ingested a toxic substance. Call Minnieville Animal Hospital immediately for urgent care.

Oral Tumors or Growths

Abnormal growths in the mouth, such as tumors or cysts, can interfere with saliva production and swallowing. While not as common as other causes, oral tumors are a possibility, especially in older cats. Warning signs may include: 

  • Thick, continuous drooling
  • A visible lump or growth in the mouth
  • Unexplained weight loss
