Bad Breath and Drooling in Cats: Causes, Symptoms, and Treatment

When your furry companion is suffering from bad breath and drooling, it’s essential to take action and identify the root cause. These symptoms can indicate a range of health issues that require prompt attention to ensure your cat’s well-being.

In this article, we will examine the various causes, symptoms, and treatment options for bad breath and drooling in cats.

Causes of Bad Breath and Drooling

Various underlying medical conditions can cause bad breath and drooling in cats. Here are some of the most common causes.

1. Oral Tumors: Tumors in a cat’s mouth or throat can cause bad breath and drooling.

These tumors can be benign or malignant and can develop at any age. 2.

Periodontal Disease: This is a bacterial infection of the gums and teeth that can cause bad breath, drooling, and tooth loss. If left untreated, it can lead to more severe health problems, such as heart and kidney disease.

3. Kidney Disease: This is a common cause of bad breath in cats due to the buildup of toxins in their bodies.

As the condition progresses, it can cause drooling and other symptoms such as weight loss and vomiting. 4.

Liver Disease: Similar to kidney disease, liver disease can cause bad breath in cats due to the buildup of toxins. The condition can cause drooling, jaundice, and gastrointestinal symptoms.

5. Diabetes: This is a metabolic disease that can cause sweet-smelling breath in cats.

The condition can cause drooling, weight loss, and increased thirst and urination. 6.

Intestinal Blockage: This is a life-threatening issue that can cause drooling, vomiting, and pain. It occurs when an object or body part obstructs the digestive system.

7. Oral Trauma: Mouth injuries such as cuts and bruises can cause bad breath and drooling in cats.

8. Respiratory Disease: Respiratory infections and illnesses such as asthma, pneumonia, and bronchitis can cause bad breath and drooling in cats.

Diagnosing Bad Breath and Drooling in Cats

When your cat is showing symptoms of bad breath and drooling, it’s essential to visit your vet immediately. Your vet will perform various diagnostic tests to determine the underlying cause of the symptoms.

These tests include:

1. Physical Examination: Your vet will examine your cat’s mouth, teeth, gums, and tongue for any signs of inflammation, tumors, or infections.

2. Blood Analysis: A blood test will check your cat’s kidney and liver functions, blood sugar levels, and red and white blood cell counts.

3. Urinalysis: A urine test will check for kidney disease and other medical conditions.

4. Abdominal Ultrasound: This test will check for any abnormalities in your cat’s organs.

5. Endoscopy: This is a minimally invasive test that uses a tiny camera and light to examine the inside of your cat’s mouth and throat.

6. Tissue Biopsy: If a tumor is suspected, your vet may perform a biopsy to remove a small sample of tissue for examination under a microscope.

7. Sedation or Anesthesia: Some tests may require sedation or anesthesia to ensure your cat’s comfort during the procedure.

Treatment and Prevention

Fortunately, there are several ways to treat and prevent bad breath and drooling in cats. Here are some of the most effective methods.

1. Tooth-Brushing: Regular tooth-brushing can prevent periodontal disease and keep your cat’s teeth and gums healthy.

2. Food Removal: Providing a healthy diet can help prevent kidney disease and liver disease.

3. Tooth Extractions: Removing damaged or infected teeth can prevent further complications and reduce bad breath.

4. Prescription Medication: Your vet may prescribe antibiotics or other medications to treat underlying medical conditions.

5. Monitoring Oral Health: Regular dental checkups can detect early signs of periodontal disease and other oral health issues.

6. Mouth Examination: Regularly examining your cat’s mouth can help you detect any changes or abnormalities early on.

7. Cleaning: Gently cleaning your cat’s mouth with a soft, damp cloth can help reduce buildup of plaque and bacteria.

Symptoms of Bad Breath and Drooling in Cats

In addition to bad breath and drooling, there are several other symptoms that indicate your cat may be suffering from an underlying condition. Here are some symptoms to watch out for:


Inability to Use Mouth: If your cat is struggling to eat or drink and avoiding using their mouth, it could be a sign of a problem with the jaw, teeth, or gums. 2.

Oral Sores: Sores in the mouth can indicate oral cancers or infections. 3.

Bleeding Gums: This is a sign of gum disease and requires prompt attention from a vet. 4.

Nausea: Some underlying conditions can cause nausea, vomiting, and a loss of appetite. 5.

Face Swelling: Swelling in the face can indicate an infection or cancer. 6.

Balance Issues: Neurological issues can cause balance problems and coordination issues. 7.

Stomatitis: This is a severe form of gum disease that causes swelling and pain in the mouth. 8.

Respiratory Issues: Respiratory infections and illnesses can cause wheezing, coughing, and breathing difficulties.


In conclusion, bad breath and drooling in cats can indicate a range of underlying medical conditions that require prompt attention. If you notice any of the symptoms described in this article, take your cat to the vet immediately to receive a diagnosis and treatment plan.

Remember to prioritize your cat’s oral health by regularly brushing their teeth, monitoring their behavior and symptoms, and maintaining a healthy diet. By keeping an eye on your cat’s health, you can help them live a happy and healthy life.

Causes of Bad Breath and Related Conditions

Bad breath and its related conditions can often be a symptom of an underlying health issue in cats. Here we look at six of the most common causes of bad breath and their related conditions.

1. Kidney Disease

One of the most common causes of bad breath in cats is kidney disease.

This condition, which can occur as cats age, can lead to a build-up of toxins in the body that can cause halitosis. Kidney disease occurs when the kidneys’ function is compromised and are no longer able to filter the blood properly.

In addition to bad breath, other symptoms of kidney disease in cats include loss of appetite, weight loss, and vomiting. Treatment for kidney disease in cats, especially in the early stages, can involve dietary changes, oral medication, and subcutaneous fluids.

2. Liver Disease

Liver disease is another common cause of bad breath and related conditions in cats.

The liver plays a vital role in digestion by producing bile to break down fats. When the liver is not functioning properly, it can cause a range of symptoms, including vomiting and a yellowing of the skin and eyes known as jaundice.

In some cases, it can also cause bad breath. When liver disease is diagnosed early, it can often be treated with medication and a specific diet, but more severe cases may require hospitalization and intensive treatment.

3. Diabetes

Diabetes is a metabolic disease that occurs when the body is unable to produce or process insulin properly.

In cats, diabetes can lead to a range of symptoms, including excessive thirst, increased urination, and weight loss. One of the more unusual symptoms of diabetes in cats is sweet-smelling breath.

This is because when the body is unable to process glucose, it can build up and cause the body to excrete ketones, leading to the sweet smell. With proper management, diabetes can be treated with a combination of diet, exercise, and medication.

4. Intestinal Blockage

An intestinal blockage is a potentially life-threatening condition that requires immediate veterinary attention.

This condition occurs when an object or body part obstructs the digestive system, leading to necrosis (tissue death) and ultimately organ failure. Symptoms of an intestinal blockage include bad breath and drooling, vomiting, and abdominal pain.

Treatment often involves surgery to remove the obstruction. 5.

Oral Trauma

Oral trauma, such as cuts and bruises, can cause discomfort and bleeding in the mouth. These injuries can lead to an infection, which can also cause bad breath in cats.

Symptoms of oral trauma include excessive drooling, difficulty eating or drinking, and avoidance of certain foods. Treatment for oral trauma in cats may involve antibiotic therapy, wound flushing, and surgical intervention if necessary.

6. Respiratory Disease

Respiratory disease can also cause bad breath in cats.

This can result from inflammation in the nostrils, sinuses, or throat. Respiratory issues such as rhinitis, sinusitis, and upper respiratory infections are common causes of bad breath in cats.

Other symptoms may include coughing, sneezing, and trouble breathing. In severe cases, respiratory disease can lead to pneumonia, which requires intensive treatment under veterinary supervision.

Prognosis for Cats with Bad Breath and Drooling

The prognosis for cats with bad breath and drooling varies greatly depending on the underlying cause. While minor health issues such as poor oral hygiene or infections can be easily treated, more severe conditions, such as kidney or liver disease and intestinal blockages, may require intensive care and ongoing management.

The cat’s initial response to treatment and overall health history can play a significant role in predicting the prognosis. In some cases, responding positively to antibiotic therapy may indicate a better overall prognosis.

However, it is important to work closely with a veterinarian to ensure appropriate diagnostic testing and early intervention for any underlying health issues.


When it comes to bad breath and drooling in cats, it is crucial to act quickly and seek veterinary care promptly. The underlying causes of these symptoms can vary greatly, and prompt attention can be critical in ensuring a favorable prognosis.

By maintaining oral hygiene, feeding a healthy diet, and detecting any potential health problems early on, you can help keep your cat healthy and happy for many years to come. In conclusion, bad breath and drooling in cats can be symptoms of a variety of underlying health issues, many of which require prompt veterinary attention.

Common causes of bad breath in cats include kidney and liver disease, diabetes, intestinal blockage, oral trauma, and respiratory disease. Treatment options vary depending on the condition’s severity, and early detection and diagnosis are crucial for successful outcomes.

Regular dental checkups, monitoring behavior and symptoms, and maintaining a healthy diet are essential components of overall cat health. By being proactive and attentive to your cat’s well-being, you can help them live a longer and healthier life.
