Flea allergy dermatitis is an uncomfortable and irritating skin condition that affects cats. It is caused by the presence of fleas and their saliva and is the most common skin condition in cats. Symptoms of flea allergy dermatitis can range from mild to severe and can include itching, inflammation, hair loss, and secondary infections. The best way to treat and prevent flea allergy dermatitis is to keep your cat free of fleas, so it is important to be aware of the signs and symptoms of this condition.

What is Flea Allergy Dermatitis?

Flea allergy dermatitis (FAD) is an allergic reaction to the saliva of fleas, which is injected into the skin when they bite. It is the most common skin condition affecting cats, and is the result of an overactive immune response to flea saliva. It is estimated that over 50% of cats in the United States suffer from FAD.

Signs and Symptoms of FAD in Cats

The first sign of FAD in cats is usually excessive scratching, especially around the tail and back. This is usually accompanied by red, inflamed skin, hair loss, and scabs. Additionally, cats may lick and chew their skin, which can lead to secondary infections. In some cases, the cat may have a flea infestation, but this is not always the case.

Itching and Scratching

The most common symptom of FAD in cats is excessive itching and scratching. Cats may appear to be constantly grooming, or may bite and chew at their fur. This is usually accompanied by red, inflamed skin, as well as hair loss and scabs. Additionally, cats may lick and chew their skin, which can lead to secondary infections.

Skin Lesions

Cats suffering from FAD often develop skin lesions, which can vary in size and severity. These lesions may appear as red, inflamed patches, scabs, or ulcers. They may also be accompanied by hair loss and intense itching, which can lead to secondary infections.

Secondary Infections

Cats suffering from FAD are more prone to developing secondary infections, due to the excessive licking and chewing of their skin. Common signs of a secondary infection include red, inflamed skin, a foul odor, and a yellowish-green discharge. In some cases, the infection may spread to other parts of the body, such as the eyes or ears.

Behavioral Changes

Cats suffering from FAD may also exhibit behavioral changes, such as irritability or aggression. Additionally, they may become withdrawn or less active than usual. These changes can be due to the discomfort caused by the condition, or the stress of dealing with the condition.

Diagnosing FAD in Cats

The diagnosis of FAD in cats is usually based on the history and physical examination. Your veterinarian may also recommend skin scrapings, blood tests, and allergens testing to rule out other causes of skin inflammation.

Treating FAD in Cats

The goal of treatment for FAD in cats is to reduce the itching and inflammation, while controlling the flea population. This may involve using flea control products, such as collars, shampoos, and topical treatments. Additionally, your veterinarian may prescribe anti-inflammatory medications, such as steroids or antihistamines, to reduce the itching and inflammation. In some cases, they may also recommend special shampoos or dietary supplements.
