Ear infections in cats are most often caused by environmental allergens or parasites. In some cases, ear infections in cats can be caused by trauma, underlying diseases, or tumors.
Ear disorders in cats are caused primarily by two different reasons; either the ear disorder is a result of a problem within the structure of the ear, or the ear disorder is caused by an outside factor. Some of the most common ear disorders in cats include: otitis, hematoma, masses within the ear canal, and feline vestibular syndrome.
Treatment options for ear infections in cats involves finding out what is causing the ear infection, and then treating the cause of the disorder. In most cases, a physical examination of the cat’s ear is all that is needed to discover the cause of the infection.
