Flea allergy dermatitis in cats

Flea allergy dermatitis in cats is caused by a reaction to the saliva of fleas. Fleas are an extremely common problem for cats. The symptoms often include extreme itching, which can lead to a skin infection. Any age of cat can develop this problem.

When fleas bite cats, their saliva goes into the bloodstream. This can cause a condition called flea allergy dermatitis. It may only take one flea bite to cause a severe reaction. This is an easy condition to treat if caught early, and it can be prevented with strict parasite control. Cats with flea allergies can live a normal and comfortable life.
