Bad breath or unpleasant breath odor in cats, also known as halitosis, is a common symptom that can indicate various health problems. It is an unpleasant odor from the cat’s mouth, which can be caused by a variety of reasons.

Can Occur with the Following Diseases:

Basics and possible causes

Bad breath in cats can be caused by a variety of factors, ranging from simple to complex medical conditions. One of the most common causes is poor oral hygiene, which leads to a build-up of bacteria in the mouth. These bacteria can accumulate on the teeth and form plaque and tartar (calculus), which then produce an unpleasant odor.

Gum diseases are also common causes of bad breath. Gingivitis and periodontitis, inflammatory conditions of the gums, can be caused by bacterial infections and often lead to strong bad breath. These inflammatory conditions can lead to tooth loss if left untreated.

Diseases of the internal organs, such as kidney or liver diseases, can also lead to bad breath. With kidney disease, the breath may smell of ammonia, while liver problems can cause a sweetish-foul odor. These conditions require immediate medical examination and treatment.

In addition, infections in the oral cavity, such as abscesses or wounds, can also cause unpleasant breath odor. Such infections can result from injuries or bite wounds and often require antibiotic or surgical treatment.

Typical accompanying symptoms

  • Increased drooling: Cats with bad breath may drool more, as saliva flow can be stimulated by inflammatory conditions or pain in the oral cavity.
  • Refusal to eat: If the bad breath is caused by pain in the mouth or dental problems, the cat may eat less or refuse to eat altogether.
  • Weight loss: Accompanying a reduced food intake, there may be significant weight loss.
  • Swelling in the face or oral cavity: Abscesses or infections in the mouth can cause swelling that is visible or palpable.
  • Changed behavior: Cats may withdraw, be less active, or rub their faces more often to relieve pain or discomfort.

When to visit the vet?

A visit to the veterinarian is absolutely necessary if the bad breath occurs suddenly and is accompanied by other symptoms such as refusal to eat, severe pain or behavioral changes. This could indicate a serious underlying problem such as an infection, an abscess or a systemic disease.

If the bad breath persists or worsens despite regular dental care, a veterinarian should also be consulted. Persistent halitosis could indicate a chronic condition that requires professional diagnosis and treatment.

If there are signs of gum diseases, such as reddened or bleeding gums, a visit to the veterinarian is also advisable to prevent worsening and to initiate appropriate measures for dental and oral care.

Symptom recognition for animal owners and veterinary diagnostic procedures

The pet owner can often recognize the bad breath by smelling the cat’s breath or observing other related symptoms such as drooling or refusal to eat. If the bad breath persists or worsens, a veterinarian should be consulted.

The veterinary diagnostic process usually begins with a thorough anamnesis and a physical examination of the cat. The veterinarian will carefully examine the cat’s mouth, teeth and gums to detect signs of dental problems, infections or injuries.

In addition, blood tests can be performed to rule out systemic diseases such as kidney or liver problems. In some cases, an X-ray or ultrasound examination may be necessary to assess the extent of dental or jaw problems.

If an infection is suspected, the veterinarian can take a sample of the affected area to identify the exact type of bacteria and determine the appropriate treatment.

What can pet owners do and professional therapy options

As a first step, the pet owner should improve the cat’s oral hygiene by regularly brushing the cat’s teeth. There are special toothbrushes and toothpaste for cats that can help reduce plaque and freshen breath.

Feeding a balanced and high-quality diet can also help support the cat’s oral health. Some pet food manufacturers offer special dental care treats or feeds that can contribute to dental health.

However, if the bad breath is persistent or severe, the pet owner should not hesitate to consult a veterinarian to determine the underlying cause and begin appropriate treatment. In many cases, only a veterinarian can determine the cause of the bad breath through a thorough examination and appropriate tests.

In addition, the pet owner should regularly check the cat’s teeth and gums and look for signs of inflammatory conditions, bleeding or swelling. Early detection and treatment of dental problems can help avoid more serious health complications.

Outlook on current research

Research on bad breath in cats examines various factors that can lead to this symptom, as well as possible treatment methods. An important aspect is the role of the oral flora. New studies have shown that the bacterial balance in the mouth is crucial for the development of unpleasant breath odor. Researchers are working to identify specific types of bacteria that are associated with bad breath in order to develop targeted treatment options.

Another area of research focuses on nutrition as a factor for bad breath. Scientists are investigating how different feed components, especially carbohydrates and proteins, can affect breath odor. It is believed that a high-protein diet can lead to a stronger odor, as the decomposition of proteins produces sulfur compounds that are perceived as unpleasant.

In addition, research is being conducted on how the general health of the cat is related to bad breath. Chronic diseases such as kidney or liver problems can affect breath odor, and researchers are trying to find out whether early detection of such diseases is possible by analyzing the breath. The development of non-invasive techniques for diagnosing diseases via the breath is a promising approach.

Innovative technologies, such as the use of electronic noses, are also being explored. These devices may be able to detect specific odor patterns that indicate certain health problems. This could provide a quick and easy way to monitor the health of cats and respond to changes early on.

Research on the genetic predisposition for bad breath is also underway. Research is being conducted to determine whether certain breeds are more susceptible to dental and oral problems that can lead to bad breath. Genetic markers could help in the future to identify cats that are at higher risk for these problems, which would allow for early intervention.

Another area of research deals with the role of dental plaque and tartar (calculus) in relation to bad breath. Studies show that removing tartar (calculus) can significantly improve breath. Researchers are developing new methods for effectively removing tartar (calculus) that are less stressful for the cat than conventional procedures.

In behavioral research, the effects of stress and anxiety on breath odor are being investigated. There is evidence that stress-related changes in saliva flow and oral flora can lead to unpleasant breath. Stress management strategies could therefore be part of a comprehensive approach to treating bad breath.

Future research may focus on how probiotic preparations affect bad breath in cats. Initial studies suggest that administering probiotic bacteria could positively influence the balance of the oral flora and thus improve breath. This type of therapy could be a gentle alternative to conventional methods.

Another interesting area of research is the investigation of the effects of dental care products for cats. The effectiveness of products such as toothpaste, mouthwashes and dental sticks is being investigated for their ability to reduce breath odor and promote oral health. Long-term studies could provide information on which products are most effective.

Collaboration between veterinarians, dentists and nutritionists is considered crucial to developing comprehensive and effective treatment strategies for bad breath in cats. Interdisciplinary approaches could lead to new insights that lead to better health and well-being for cats.
