Asthma in cats is a chronic inflammatory disease of the airways triggered by hypersensitivity to environmental allergens. It is estimated to affect up to 1% of the cat population, with a higher incidence in young to middle-aged cats. The disease leads to a narrowing of the bronchi, which can lead to a cough, shortness of breath, and in severe cases, life-threatening respiratory distress and suffocation. Treatment traditionally involves corticosteroid and bronchodilator medications. Another research focus is on immunotherapy, which aims to modulate the allergic reaction.

Genetic factors: There is evidence that genetic factors may play a role in susceptibility to feline asthma. Certain breeds, such as Siamese and Orientals, appear to be more commonly affected. Scientists suspect that genetic predispositions, combined with environmental factors, increase the likelihood of developing asthma.

Respiratory infections can lead to airway sensitization in some cats and contribute to the cat developing asthma later in life. Infections often lead to chronic inflammation, which makes the airways more susceptible to asthma attacks.

Diagnosing feline asthma can be difficult because the symptoms often resemble other respiratory diseases, such as chronic bronchitis or infections. However, there are several diagnostic procedures available to veterinarians, such as X-rays, bronchial lavage samples (bronchoalveolar lavage, BAL), blood tests, and possibly allergy tests.

New Scientific Findings

In immunotherapy, cats are exposed to controlled small amounts of the previously identified triggering allergen over a longer period of time to reduce the sensitivity of the immune system. In addition to traditional injection therapy, there is also sublingual immunotherapy (SLIT), in which the allergen is administered as drops or a spray under the cat’s tongue. This method has the advantage of being less invasive and can be performed at home. Intensive research is being carried out into the use of immunomodulators, which specifically influence the immune system. Work is also being carried out on more specific allergen mixtures for testing. This also enables improved, personalized therapy for affected cats.

While the influence of environmental factors such as allergens is well researched, the genetic component is increasingly becoming the focus of science.

The hypothesis that genetic factors play a role in the development of feline asthma has long been discussed, especially since certain cat breeds appear to be more frequently affected by the disease. Siamese and Oriental Shorthair cats, for example, show an increased prevalence of asthma. Current research approaches.

A promising approach in the research of genetic markers for feline asthma are so-called genome-wide association studies (GWAS). These studies examine the entire genome of cats and compare genetic differences between affected and unaffected animals. The aim is to identify specific genetic variants that are more common in asthmatic cats. Initial GWAS studies in cats have already identified some promising regions in the genome that may be associated with an increased susceptibility to asthma.

Since feline asthma is an immune-mediated disease, many genetic studies focus on genes involved in the immune response and play an important role in the inflammatory response.

Researchers are also investigating genes responsible for the function of special cells (T helper cells), as these cells play a key role in allergic reactions.

Current studies are investigating possible genetic markers that could indicate a predisposition to the disease even before symptoms appear. This could not only deepen the understanding of this disease, but also open up new avenues for diagnosis and treatment and support responsible breeders in targeted pairings. Cats with a predisposition to asthma could be excluded from breeding.

Frequently Asked Questions (FAQs)

  1. How do I know if my cat has asthma?
    Typical signs of feline asthma include cough, respiratory distress, panting, and rapid, shallow breathing. A veterinarian can make an accurate diagnosis.
  2. Is feline asthma curable?
    No, feline asthma is not currently curable, but it can be well managed with medication and environmental adjustments.
  3. Can I prevent asthma attacks in my cat?
    Yes, by minimizing allergens in the environment and following the veterinarian’s treatment plan, asthma attacks can be significantly reduced.
  4. What happens if asthma is left untreated?
    Untreated asthma can lead to severe respiratory distress, irreversible lung damage, and, in the worst case, death.
