In this chapter, we will delve into some of the most common causes of excessive drooling in cats so that you can better understand what might be triggering this issue in your feline companion.

Dental Issues

The most common cause of excessive drooling in cats is related to dental issues. If your cat has dental problems such as gum disease, tooth decay, or oral ulcers, they may be experiencing pain or discomfort in their mouth, leading to increased drooling. Additionally, objects stuck between your cat’s teeth or foreign bodies lodged in their mouth can also cause excessive drooling. It is important to regularly inspect your cat’s teeth and gums for any signs of dental issues, and to take them to the vet for regular dental check-ups to prevent and address any problems that may be causing excessive drooling.

Toxins and Poisoning

Your cat may experience excessive drooling as a result of ingesting toxins or poisons. Household items such as certain plants, cleaning products, and human medications can be toxic to cats and lead to excessive drooling. Moreover, some human foods and essential oils can also be harmful to cats, causing them to drool excessively. Make sure to keep these items out of your cat’s reach, and be aware of any potential sources of poisoning in and around your home. If you suspect that your cat has ingested a toxic substance, seek immediate veterinary attention to address the issue and prevent any serious health complications.

Health-related Factors

Some health-related factors can contribute to your cat’s excessive drooling. It is important to consider the following:

  • Oral diseases and injuries
  • Systemic illnesses
  • Any recent changes in your cat’s behavior or health

Oral Diseases and Injuries

If your cat has excessive drooling, it may be a sign of oral diseases or injuries. These can include dental issues such as periodontal disease, oral tumors, foreign objects stuck in the mouth, or injuries to the tongue or gums. It’s important to have your cat’s oral health evaluated by a veterinarian to rule out any potential problems.

Systemic Illnesses

Excessive drooling in cats can also be a symptom of systemic illnesses such as kidney disease, liver disease, diabetes, or respiratory infections. These conditions can affect your cat’s overall health and may require immediate medical attention. If you notice excessive drooling along with other concerning symptoms, it’s crucial to seek veterinary care for your cat as soon as possible.

Behavioral and Environmental Considerations

Not all cases of excessive drooling in cats are caused by medical issues. Sometimes, it’s important to consider your cat’s behavior and environment to understand the reason behind the drooling.

Stress and Anxiety

If your cat is feeling stressed or anxious, it may result in excessive drooling. Common stressors for cats include changes in their environment, new additions to the family, or loud noises. If your cat is drooling more than usual and exhibiting other signs of stress, such as hiding, excessive grooming, or loss of appetite, it’s important to address the underlying cause and seek help from a veterinarian if needed.

Interaction with Certain Plants or Substances

Your cat may also be drooling excessively due to interaction with certain plants or substances in your home. Some common household plants, such as lilies, are highly toxic to cats and can cause excessive drooling, vomiting, and even kidney failure. Additionally, exposure to toxic substances like cleaning products, insecticides, or human medications can also lead to drooling in cats. It’s crucial to keep these harmful items out of your cat’s reach to prevent any accidental ingestion and subsequent drooling.

Diagnosis and Treatment

After identifying the possible reasons why your cat is drooling, it’s important to consult with a veterinarian to determine the exact cause and the appropriate treatment.
