Cats, those enigmatic creatures that grace our homes with their presence, can exhibit peculiar behaviors that sometimes leave us baffled. One such behavior is salivation. While a bit of drool here and there is considered normal, excessive salivation or foaming can be a cause for concern. In this article, we delve into the intriguing world of feline salivation, uncovering the reasons behind this phenomenon.

Common Reasons for Cat Salivation

Normal Occurrences


Cats are meticulous groomers, and licking cat foaming at the mouth themselves is a natural part of their routine. However, excessive grooming can lead to increased salivation.


The soothing sound of a cat’s purr is one of the joys of having them as pets. Interestingly, purring can stimulate saliva production, contributing to occasional drooling.

Health Issues

Dental Problems

Poor oral health can result in increased salivation. Cavities, gum disease, or tooth infections can lead to discomfort, prompting excessive drooling.


Ingesting toxic substances, such as certain plants or household chemicals, can cause a cat to salivate excessively as the body tries to eliminate the harmful elements.

Oral Infections

Infections in the mouth, like stomatitis or gingivitis, may lead to inflammation and increased saliva production.

Environmental Factors

Stress and Anxiety

Cats, being sensitive creatures, may exhibit stress-induced behaviors, including excessive salivation. Changes in the environment, new pets, or loud noises can trigger stress.

Temperature Sensitivity

Extreme temperatures, especially heat, can make cats pant and salivate more to regulate their body temperature.

Foamy Salivation: Causes and Concerns

Introduction to Foamy Salivation

Foamy salivation is a more concerning form of excessive drooling. It may indicate underlying health issues that require attention.

Potential Health Issues

Conditions like respiratory infections, toxins affecting the nervous system, or organ failure could manifest in foamy salivation, demanding prompt veterinary care.

What to Do If Your Cat Is Salivating Excessively

Home Care Tips

  1. Observe Behavior: Monitor your cat’s behavior, looking for signs of distress or discomfort.
  2. Gentle Cleaning: If the drooling is due to grooming, gently clean the fur around the mouth to prevent skin irritation.

When to Consult a Vet

  1. Persistent Salivation: If excessive salivation persists for more than a day, consult your veterinarian.
  2. Accompanied by Other Symptoms: Seek immediate vet attention if salivation is accompanied by lethargy, vomiting, or changes in appetite.

Prevention and Maintenance

Regular Dental Check-ups

Scheduled dental check-ups can prevent oral issues, reducing the likelihood of excessive salivation.

Providing a Stress-Free Environment

Creating a calm and comfortable space for your cat can minimize stress-related behaviors.

Proper Diet and Nutrition

A balanced diet supports overall health, reducing the risk of nutritional deficiencies that could contribute to salivation.


Understanding the reasons behind cat salivation empowers cat owners to provide better care for their feline companions. While occasional drooling may be harmless, persistent or foamy salivation warrants attention to ensure the well-being of your furry friend.
