Some nasal dermatoses may heal with time, but if the condition does not go away within a week, you should contact your veterinarian to find out what is the cause of the problem and if any special medication or treatment is necessary.

There are many types of skin diseases that may develop on the nose of a cat. We would consider a fungal or bacterial infection, cat acne, a bite wound, cancer or other condition that causes nasal lesions.

The symptoms may vary according to the origin of the skin disease, but usually consist of:

Some of the most common nose skin diseases in cats are:

In order to correctly diagnose nose skin disease in cats, your veterinarian will ask questions about the medical history of the cat, including changes in your cat’s lifestyle, when the symptoms started and if you remember anything that may cause lesions such as recent sun exposure or an insect bite. The vet may take samples of skin from the nose to culture for fungi and bacteria testing or to do a biopsy. Diagnostic tests may be recommended to rule out some of the possible causes of skin disease, because some symptoms are seen in several different skin diseases. Other diagnostic tests may include examining hair and skin under a microscope, analysis of scabs, and blood tests for allergies. The doctor may also monitor how your cat responds to a trial of dietary modification or medical therapy.

Once the veterinarian determines the cause of the skin disease, he or she can prescribe a treatment. In some cases, a combination of treatments may be recommended to relieve symptoms and discomfort. Some of the possible treatments are:

Surgery may be required to open and drain the abscesses and flush out the pus. If there is infection, the appropriate antibiotic will be prescribed. Most also require anti-inflammatories and pain relief.

The veterinarian may want to surgically remove lesions before prescribing antifungal medication. There are several different antifungal medications that may be used. Some require nasal washes under anaesthetic.

Antihistamines and/or steroids will be prescribed, and if the lesions are ulcerated, a wet dressing may be applied. The doctor will also protect the area so that your cat cannot self-inflict trauma; this is often achieved with a buster collar.

Your cat must avoid further exposure to direct sunlight, especially between the hours of 10am – 3pm during the summer. In some cases, feline sunblock and steroids may be prescribed. 

Since this is a fungal infection, antifungal medication is prescribed. Depending on the severity of the lesions, the doctor may want to remove any plauqes prior to administering fungal medication.

Depending on the severity and cause of the nose skin disease, the predicted outcome of treatment is usually good. It may take a week or more for the medications to clear up the disease completely. It is recommended to take your cat back to the veterinarian after the nose heals to make sure all the symptoms are gone. 

There are some things you can do to help prevent skin diseases, starting with feeding a balanced diet and providing good grooming. Make sure your cat is not exposed to known allergens such as certain foods, dust mites and plastics. Your doctor can help with this after diagnosing the nose skin disease. If your cat has white ears and a pink nose, keep it out of the sun during the peak hours of sunlight. Even sunbathing through a window can cause sunburn so consider blinds if your cat is a sun worshipper. It is also recommended to have your cat neutered because this will help keep it out of fights that could result in an injury on the nose.
