Bad breath, or halitosis, is a common issue in cats that can indicate various health problems. While occasional mild bad breath might not be a cause for concern, persistent or severe bad breath warrants further investigation.
Is Bad Breath Normal for Cats?
While it is common for cats to have mild breath odor occasionally, persistent or severe bad breath (halitosis) is not normal and often indicates an underlying health issue. Occasional minor breath odor might not be alarming, especially after eating specific foods, but if your cat's breath consistently smells foul, it is important to investigate further. Chronic bad breath can be a sign of dental disease, infections, or systemic conditions that require veterinary attention.
What Is Bad Breath?
Bad breath, or halitosis, refers to an unpleasant odor emanating from the mouth. In cats, this is often caused by bacteria breaking down food particles, releasing smelly sulfur compounds. Poor dental hygiene, tartar buildup, and periodontal disease are common culprits, but bad breath can also be a symptom of more serious health problems such as kidney disease, liver disease, or diabetes. Understanding the root cause of halitosis is crucial for proper treatment and management.
Symptoms Associated with Bad Breath in Cats
Your family pet might like to rub noses with you or the kids, giving you a great chance to get a whiff of its breath. When a foul-smelling odor startles you, then your cat might have a significant problem. Here are the symptoms that may accompany bad breath in cats:

Why Does My Cat's Breath Smell So Bad?
Dental Disease
Bad breath in cats, also known as halitosis, is commonly caused by dental disease. Conditions such as gingivitis, periodontal disease, tooth abscesses, and tartar buildup are primary culprits. Gingivitis involves inflammation of the gums due to plaque buildup, while periodontal disease is a more severe form where bacteria infect the tissues surrounding the teeth. Tooth abscesses and tartar buildup also harbor bacteria that produce foul odors, contributing to bad breath.
Oral Infections
Oral infections are another significant cause of bad breath in cats. Conditions like stomatitis, which involves inflammation and ulceration of the mouth's mucous membranes, can cause severe bad breath. Oral ulcers and fungal infections such as candidiasis also contribute to unpleasant mouth odors. These infections can result from poor oral hygiene, systemic health issues, or injuries to the mouth.
Diet and Eating Habits
Diet and eating habits play a crucial role in a cat’s oral health. Certain foods can contribute to bad breath, especially if they are not suited to the cat’s dietary needs. Additionally, cats that scavenge or eat non-food items can develop foul-smelling breath. Ensuring your cat has a balanced diet appropriate for its health requirements can help mitigate this issue.
Systemic Diseases
Systemic diseases such as kidney disease, diabetes, and liver disease are major factors that can lead to bad breath. Kidney disease often results in uremic breath that smells like ammonia due to the buildup of waste products in the blood. Diabetes, particularly when it leads to diabetic ketoacidosis, can cause a sweet or fruity odor in the breath. Liver disease may cause a foul odor, often accompanied by other symptoms such as jaundice.
Gastrointestinal Issues
Gastrointestinal issues can sometimes be the underlying cause of bad breath. Digestive disorders can lead to unpleasant odors from the mouth, especially if the cat experiences frequent vomiting. Vomiting can leave residual stomach acids and partially digested food in the mouth, contributing to bad breath. Ensuring proper digestion and addressing any gastrointestinal problems is crucial for maintaining oral health.
Respiratory Infections
Respiratory infections, including upper respiratory infections and sinus infections, can also cause bad breath in cats. These infections lead to the presence of bacteria in the respiratory tract, which can affect the mouth and produce foul odors. Treating these infections promptly is essential to prevent secondary oral health issues that contribute to bad breath.
Poor Oral Hygiene
Poor oral hygiene is a significant and often preventable cause of bad breath. Without regular dental care, plaque and tartar can accumulate, leading to dental disease and bad breath. Additionally, dental trauma, such as broken or damaged teeth, can become infected and produce unpleasant odors. Regular brushing with cat-specific toothpaste and routine veterinary dental check-ups are vital to maintaining your cat’s oral health and preventing bad breath.
Diagnosis of Bad Breath in Cats
Physical Examination
Diagnosing bad breath in cats starts with a comprehensive physical examination. The veterinarian will inspect the mouth for visible signs of dental disease, such as tartar buildup, gum inflammation, oral ulcers, and tooth abscesses. They will also look for oral lesions, lumps, sores, and other indicators of infection. Additionally, the vet will assess the cat’s general health, including weight, coat quality, and hydration status, to get an overall picture of the cat's condition.
Dental X-Rays
Dental X-rays are essential for uncovering issues not visible during the physical exam. These X-rays help detect tooth root abscesses, assess bone loss around the teeth indicative of advanced periodontal disease, and identify hidden dental problems such as fractures or retained roots. This imaging is crucial for a thorough evaluation of the cat's oral health.
Blood Tests
Blood tests provide critical information about the cat’s overall health and can reveal systemic diseases that might cause bad breath. A complete blood count (CBC) evaluates the cat’s general health, detecting infections, inflammation, and anemia. A biochemistry profile assesses organ function, particularly the liver and kidneys, which are often linked to bad breath if they are compromised.
Urinalysis
Urinalysis is used to diagnose systemic conditions, especially those affecting the kidneys. This test evaluates kidney function, checking for signs of kidney disease, which can cause uremic breath. It also detects glucose or ketones in the urine, indicative of diabetes, another condition that can lead to bad breath in cats.
Oral Swabs and Cultures
If an infection is suspected, oral swabs are taken for laboratory analysis. This helps identify specific bacteria causing oral infections and detect fungal infections such as Candida. By pinpointing the exact type of infection, the veterinarian can prescribe the most effective treatment to address the underlying cause of bad breath.
Biopsy
In cases where tumors or unusual growths are found in the mouth, a biopsy is performed. This procedure determines whether the growth is benign or malignant, guiding the treatment plan based on the biopsy results. Identifying the nature of the growth is crucial for addressing any potentially serious conditions contributing to bad breath.
Additional Diagnostic Imaging
Further diagnostic imaging, such as ultrasound or advanced radiographs, may be necessary to evaluate internal organs and identify systemic issues contributing to bad breath. This imaging helps assess the liver, kidneys, and gastrointestinal tract, as well as detect problems in the nasal passages or sinuses that could affect oral health. Comprehensive imaging ensures that all potential causes of bad breath are thoroughly investigated and appropriately treated.
How to Treat Bad Breath in Cats
Professional Dental Cleaning
Professional dental cleaning is a common and effective treatment for bad breath in cats. This procedure includes scaling and polishing to remove plaque and tartar from the teeth and under the gum line, preventing periodontal disease. Severely damaged or infected teeth that cannot be saved are extracted. Additionally, fluoride treatment is applied to strengthen the teeth and reduce plaque formation, contributing to better oral hygiene and fresher breath.
Medications
Medications are prescribed to address infections or other underlying health issues causing bad breath. Antibiotics treat bacterial infections such as gingivitis or tooth abscesses, while antifungals are used for fungal infections like candidiasis. Pain relievers help manage discomfort from dental procedures or oral infections, and anti-inflammatories reduce inflammation and pain associated with dental disease or stomatitis.
Dietary Changes
Adjusting your cat's diet can significantly improve oral health and reduce bad breath. Special dental diets are formulated to reduce plaque and tartar buildup. Ensuring your cat drinks plenty of water helps wash away food particles and bacteria, and avoiding certain foods that contribute to bad breath in favor of a balanced diet suitable for your cat’s health needs can make a noticeable difference.
Regular Oral Hygiene
Maintaining good oral hygiene is crucial for preventing and treating bad breath in cats. Regularly brushing your cat’s teeth with cat-specific toothpaste helps significantly reduce plaque buildup. Providing dental chews and toys that promote chewing can clean the teeth and gums, and adding dental water additives to your cat’s drinking water can help reduce bacteria in the mouth.
Treatment for Systemic Diseases
If bad breath is caused by a systemic disease, treating that underlying condition is essential. For kidney disease, management includes dietary changes, medications, and possibly fluid therapy to support kidney function. Diabetes management involves insulin therapy, dietary modifications, and regular monitoring of blood glucose levels. Liver disease treatment may involve medications, dietary changes, and addressing any underlying conditions affecting liver function.
Oral Surgery
Oral surgery may be necessary in some cases to treat severe dental disease or remove tumors. This includes surgical excision of benign or malignant growths in the mouth and advanced dental procedures such as root canals or advanced periodontal treatments to save and restore damaged teeth. These surgical interventions help resolve severe issues that contribute to bad breath and improve overall oral health.
Recovery of Bad Breath in Cats
Recovery of bad breath in cats depends on the underlying cause and the treatment provided. Key factors include:
- Effective Treatment: Addressing dental issues, infections, or systemic diseases promptly.
