Atopic or Allergic Dermatitis is a common skin condition seen in cats, caused by inflammation that follows an allergic reaction to environmental allergens¹.

It’s a type of immune-mediated disease, with affected cats seeming to have a genetic predisposition to developing hypersensitivity to allergens in their environment¹.

Symptoms

The most common symptoms of atopic dermatitis in cats usually include¹²:

1. Itching: Cats with this condition often exhibit signs of skin irritation, such as excessive scratching, licking, and biting³.
2. Ear Infections: Otitis externa, or ear infections, are common¹.
3. Skin Infections: Recurrent skin lesions and skin infections, known as pyoderma, are often seen¹.
4. Hair Loss: Alopecia, or hair loss, is another symptom¹.
5. Raised Areas of Pink or Red Sores on Skin: These are also known as eosinophilic granuloma¹.
6. Irritability and Behavior Changes: These can also occur as a result of the discomfort¹.

Causes

Atopic Dermatitis in cats is caused by an immune hypersensitivity to environmental allergens¹.

Common allergens that trigger atopic dermatitis include pollen, dust, dust mites, mold, wool or nylon, and certain plastics⁴.

Exposure to these allergens can happen both outdoors and indoors⁴.

Effects

Atopic Dermatitis can lead to a variety of effects on a cat’s health and behavior.

The constant itching and discomfort can lead to behavior changes and irritability¹.

Chronic skin infections can lead to scarring and changes in skin color⁵.

Hair loss from excessive scratching or licking can also occur¹.

In severe cases, the skin may become thickened².

Treatment

Treatment for Atopic Dermatitis in cats often involves a combination of medications, environmental management, and allergy testing⁶.

Some of the common treatment options include¹:

1. Corticosteroids: These are used to reduce inflammation and itching.
2. Antihistamines: These can help control itching.
3. Antibiotics: These are used for treating secondary infections.
4. Immunosuppressive Medications: These can help control the immune system’s response.
5. Allergen-Specific Immunotherapy: This involves exposing the cat to small amounts of the allergen to help build tolerance.
6. Omega Fatty Acid Supplements: These can help improve skin health.
7. Shampoos and Baths: These can help soothe the skin and control symptoms.

In addition to these treatments, allergen avoidance is sometimes possible if the allergen is identified¹.
