What is Flea Allergy Dermatitis?

Flea allergy dermatitis as the name implies is an allergy which affects both cats and dogs. It is a skin condition which occurs when a flea bites a cat and the cat is hypersensitive to the flea’s saliva. Flea saliva contains many antigens which some cats and dogs are very susceptible to. Your cat does not have to have many fleas because just one bite from a flea can trigger an allergic reaction. Flea Allergy Dermatitis is a very itchy and painful disorder and is the most common allergy in cats and dogs.

Flea Allergy Dermatitis is often seasonal with it occurring more often in the warmer summer and fall months. It occurs in direct relation to the period of time when fleas are most prevalent. In warmer countries Flea Allergy Dermatitis can persist year round as fleas tend not to die off in winter. Cooler temperatures and low humidity tend to inhibit flea development.

What are the Symptoms of Flea Allergy Dermatitis?

Symptoms include severe itching and inflammation of the skin. The cat will groom itself for hours and scratch, bite and lick at affected areas often causing damage to the skin. Cats can develop small crusts or scabs on the body (miliary dermatitis). Hair loss may occur mainly on the rump and extending up the back.
Damage done to the skin is a direct result of self mutilation by the cat itself because of the severe itchiness.

Secondary bacterial and yeast infections are common in chronic cases of flea allergy dermatitis and you may notice an unpleasant odor coming from your cat because of this.

What is the Treatment for Flea Allergy Dermatitis in Cats?

It is probably quite obvious that you need to get rid of fleas from your cat. Just one single flea can cause terrible symptoms.

Antibiotics and antifungal medication my be prescribed by your vet to treat the secondary bacterial or yeast infections. Your vet may put your cat on a short course of prednisone to relieve the inflammation. Sometimes antihistamines are prescribed. However, the only long term treatment for flea allergy dermatitis is total flea control and not allowing one single flea to come in contact with your cat.
Desensitizing shots tend not to work well with Flea Allergy Dermatitis.
