When to visit the vet?
Urgent see a veterinarian within 24 hours
RED for respiratory distress, mouth breathing, cyanosis, acute severe nosebleeds, or if the polyp causes acute obstruction. ORANGE (promptly) for chronic obstruction, snoring/stridor, or recurrent otitis.

Definition
New growths in the nasal passages in cats, also known as polyps, are benign tissue growths that can develop in the nasal cavity or nasal passages. These growths often lead to respiratory problems and other symptoms that can affect the cat’s well-being.
Can Occur with the Following Diseases:
Basics and possible causes
Polyps in the nasal passages of cats are relatively rare but can occur in cats of any age. They consist of soft, mucous membrane-like tissue and are generally benign, meaning they are not cancerous. The exact cause of polyp formation is not fully understood, but it is believed that chronic inflammatory conditions or infections may play a role.
A possible cause for the development of polyps could be chronic irritation or rhinitis, caused by repeated infections, allergies, or foreign bodies. Genetic factors could also play a role, as certain cat breeds may be more susceptible to developing polyps.
Another possible trigger for polyps are viral infections, particularly feline herpesvirus and feline calicivirus, which commonly cause respiratory diseases in cats. These viruses can cause chronic inflammatory conditions and damage to the nasal tissue, which can lead to the formation of polyps.
Typical accompanying symptoms
-
Sneezing: Frequent and persistent sneezing can be an initial sign of the presence of polyps in your cat’s nasal passages. This occurs due to the irritation and pressure that the growths exert on the nasal mucous membrane.
-
Nasal discharge: A clear or purulent nasal discharge, which can occur unilaterally or bilaterally, is another typical symptom. The discharge can be caused by the blockage and inflammation in the nasal passages.
-
Respiratory distress: Cats with polyps may develop breathing sounds such as snoring or rattling, especially when inhaling. These sounds are caused by the obstruction of airflow in the nasal passages.
-
Facial swelling: In some cases, there may be slight swelling in the face, especially around the nose or eyes, if the polyps are large enough to exert pressure on the surrounding tissue.
-
Reduced sense of smell: Cats with polyps may have a reduced sense of smell, which can affect their eating behavior, as smell is an important factor in food intake.
-
Mouth breathing: In severe cases, cats breathe through their mouth, especially if the nasal passages are severely narrowed or blocked. This is a serious symptom that requires immediate veterinary attention.
-
Loss of appetite and Weight loss: Due to the obstructive symptoms, cats may eat less and lose weight, indicating a general deterioration of their health.
When to visit the vet?
A visit to the veterinarian is urgently required if your cat shows symptoms of respiratory distress, especially if they are breathing through their mouth or there is a noticeable change in behavior or food intake. These symptoms can indicate a serious airway obstruction that requires immediate medical intervention.
If your cat has persistent nasal discharge that is not due to a short-term infection, a veterinarian should also be consulted. Long-lasting discharge can indicate a chronic condition or the presence of polyps or other growths.
Additionally, a veterinarian should be consulted if there are signs of facial swelling or other unusual swelling in the head area. These could indicate a growth that needs to be diagnosed and treated.
Symptom recognition for animal owners and veterinary diagnostic procedures
Detecting polyps in a cat’s nasal passages can be challenging for pet owners, as symptoms often start subtly and gradually worsen. Pet owners should look for and observe signs such as frequent sneezing, persistent nasal discharge, or unusual breathing sounds.
The veterinary diagnostic process usually begins with a thorough clinical examination, during which the veterinarian inspects the cat’s head and nasal region. A nasoscopy or rhinoscopy may be necessary to examine the nasal passages more closely and directly visualize polyps.
In addition, imaging procedures such as X-rays or computed tomography (CT) can be used to determine the extent and exact location of the polyps. These procedures also help rule out other possible causes for the symptoms, such as tumors or foreign bodies.
In some cases, the veterinarian may perform a biopsy of the polyps to make a definitive diagnosis and ensure that they are benign growths. The biopsy is usually performed under sedation or anesthesia to spare the cat stress and discomfort.
What can pet owners do and professional therapy options
As a pet owner, you can take some measures to support your cat’s well-being until the veterinary visit. Ensure your cat remains in a stress-free environment, as stress can worsen respiratory problems. Keep the area around the nose clean and carefully remove any discharge with a soft, damp cloth.
It is important to ensure your cat drinks enough fluids to avoid dehydration, especially if they are eating or drinking less due to nasal congestion. You can encourage your cat to drink more by providing fresh water or flavoring it with some chicken broth, as long as it does not contain onions or garlic.
Avoid using strong cleaning agents, fragrances, or smoke in your cat’s environment, as these can further irritate the airways. If your cat has difficulty eating, try offering wet food in smaller, more frequent meals to stimulate appetite.
It is important not to administer any medications or home remedies without consulting a veterinarian, as these can worsen symptoms or have undesirable side effects. The veterinarian can give you the best recommendations on how to alleviate your cat’s condition while you await professional treatment.
Outlook on current research
Current research on nasal polyps in cats focuses on the causes and mechanisms of their development. Scientists are investigating genetic predispositions to understand why some cats are more susceptible to these growths than others. It is believed that both genetic and environmental factors could play a role. Research has shown that chronic inflammatory conditions and upper respiratory infections may contribute to the formation of polyps. These inflammatory conditions could be triggered by viruses, bacteria, or allergens.
Another area of research deals with diagnostic methods. Advances in diagnostic imaging, such as high-resolution computed tomography (CT), allow for more precise visualization of the nasal passages. These technologies help veterinarians identify polyps early and accurately, leading to better treatment planning. The use of endoscopy for direct viewing and sampling is also an important step in diagnosis.
There are also advances in the treatment of nasal polyps in cats. New surgical techniques, including minimally invasive procedures, are being explored to make polyp removal safer and more effective. Researchers are also investigating the role of medications that could slow or prevent the growth of polyps. This includes the study of anti-inflammatory drugs and immunomodulators. Long-term studies are underway to evaluate the efficacy and safety of these treatment methods.
Additionally, the influence of environmental factors on polyp formation is being investigated. Researchers are analyzing how air quality, living conditions, and nutrition affect the risk of nasal polyp formation. The goal of these studies is to develop preventive measures that could reduce the occurrence of polyps in cats. Better education for cat owners about the importance of a clean and stress-free environment could also play a role in prevention.
Another branch of research focuses on the role of the immune system in the development of polyps. Scientists are investigating how the immune system reacts to chronic inflammatory conditions in the nasal passages and whether there are ways to modulate these reactions. Understanding the immunological mechanisms could lead to innovative treatment approaches that prevent the formation of polyps or their recurrence after removal.
Finally, genetic research is also being advanced to identify potential genetic markers for susceptibility to nasal polyps. These markers could be considered in cat breeding in the future to minimize the occurrence of this disease. Genetic tests could also help identify at-risk patients early and initiate preventive measures.
