Cat fleas are a condition that should not be taken lightly. If your cat has fleas, they can cause or worsen the existing cat ear problems your cat already has. Cat ears are one of the most sensitive areas where fleas generally cause or worsen skin irritations.
Many cats have conditions such as food allergies and environmental allergies. Some cats are allergic to pollen, molds, and dust mites just like some people are. Allergies can cause cats to have some of the same symptoms that are shown with fleas such as itching, redness, cat ear problems and skin infection. These symptoms of cat ear problems will be made even worse by the irritation caused by cat fleas. Cats that are already prone to ear and skin infection due to their allergies will be even more vulnerably to these infections because of open wounds from biting cat fleas and the irritation from scratching at their itchy ears constantly. These infected lesions on or around the ears can lead to complications.
The area where fleas will often feed on the ear is on the skin of the ear flap. A sign that fleas have been feeding on the ears is dried blood on the ear flap. You will not find this on a cat that only has allergy ear issues and no fleas. If you cannot find the fleas, themselves, in your cats coat look for the flea feces. The flea feces look like small black dots through the coat. Cats with fleas often have flea allergy dermatitis. This skin disease occurs when cats have an allergic reaction to flea saliva. These cat ear problems caused by cat fleas leads to skin and ear infection, hair loss, scratching at the head neck and ears, redness, rash and sores. It is important to deal with any of these cat ear problems by taking your pet to the veterinarian as soon as possible. Skin and ear infections can become serious health issues for your cat if they are left untreated.
