Is your cat drooling more than usual? While occasional drooling in cats can be normal, excessive or unusual drooling might indicate an underlying health issue. Understanding the reasons behind your cat's drooling can help you determine whether it’s a harmless quirk or a sign to call the vet.

😺 When Cat Drooling Is Normal

Drooling in cats isn’t always a cause for concern. Certain situations can trigger a bit of saliva, and in these cases, it’s usually nothing to worry about. Here are some common reasons why your cat might drool normally:

  • Happy relaxation – Some cats drool when they’re kneading, purring, or feeling particularly content. This behavior is often linked to kittenhood when they drooled while nursing.
  • Food anticipation – Drooling can occur when your cat is excited about food or treats. The smell of a tasty meal may stimulate their salivary glands.
  • Medication – If your cat has recently been given oral medication, drooling may be a temporary reaction to the taste or texture.

In these scenarios, the drooling is typically mild, temporary, and not accompanied by other symptoms. Keep an eye on your cat’s behavior to ensure there are no additional signs of discomfort.

🚩 When Cat Drooling Is Not Normal

Excessive or unexplained drooling, also known as hypersalivation, could be a sign of a medical issue. If your cat is drooling persistently or showing other concerning symptoms, it’s time to investigate further. Common causes of abnormal drooling include:

🐾 Dental Disease

According to PetMD, dental issues are a leading cause of excessive drooling in cats (source). Problems like gingivitis, tooth decay, or oral infections can cause pain and excess saliva. Look for these symptoms:

  • Bad breath
  • Red, swollen gums
  • Difficulty eating or chewing

🌱 Ingesting Toxic Substances

Drooling can occur if your cat has licked or ingested something toxic. Common household toxins include certain plants (like lilies), cleaning products, and human medications. Symptoms of poisoning may include:

  • Vomiting
  • Lethargy
  • Seizures

If you suspect poisoning, contact your vet or a pet poison hotline immediately.

🐜 Foreign Objects

If your cat gets a small object, string, or bone fragment stuck in their mouth or throat, it can lead to drooling. You may notice additional signs like pawing at their mouth or gagging.

🐾 Nausea or Digestive Issues

Cats may drool when they feel nauseous. This can be caused by a range of issues, including motion sickness, gastrointestinal problems, or kidney disease. Watch for other symptoms such as:

  • Vomiting
  • Loss of appetite
  • Diarrhea

🧪 Viral or Bacterial Infections

Infections like feline calicivirus can cause oral ulcers, leading to drooling. Cats with infections may also exhibit:

  • Fever
  • Sneezing or nasal discharge
  • Decreased energy

🧠 Neurological Issues

Neurological conditions, such as facial nerve paralysis or seizures, can affect a cat’s ability to control their saliva. This type of drooling is often accompanied by other neurological symptoms, such as uncoordinated movements or head tilting.

🩺 What to Do if Your Cat Is Drooling

If your cat’s drooling seems abnormal, follow these steps to assess the situation and seek appropriate care:

👀 Observe Your Cat

Watch for other symptoms like changes in appetite, behavior, or energy levels. Take note of when the drooling started and any potential triggers, such as exposure to toxins or recent injuries.

🧼 Check Their Mouth

If your cat allows it, gently check their mouth for signs of dental issues, ulcers, or foreign objects. Be cautious, as a cat in pain may react defensively.

📞 Call Your Vet

If the drooling persists or is accompanied by other concerning symptoms, contact your veterinarian. They may recommend bringing your cat in for an examination or provide advice based on the situation.

🚨 Emergency Situations

Seek immediate veterinary care if your cat is drooling excessively and showing severe symptoms such as difficulty breathing, seizures, or extreme lethargy. These could indicate a life-threatening condition.

💡 How to Prevent Drooling Issues

While some causes of drooling are unavoidable, there are steps you can take to minimize risks:

  • Schedule regular dental checkups to maintain oral health
  • Keep toxic plants and substances out of reach
  • Provide a safe environment to reduce the risk of ingesting foreign objects
  • Ensure your cat is up to date on vaccinations to prevent infections

By staying proactive, you can help ensure your cat stays happy and healthy.
