Cats may also develop ear infections due to ear trauma, tumors in the ear, or even if an object becomes lodged deep within the ear. Though these are rarer causes of ear infections in cats, veterinarians still see many cats each year that are suffering from ear infections due to these causes. Ear trauma can occur from constant itching, scratching, and head shaking from allergies, and tumors in the ear may be caused by some types of cancers. In some cases objects, such as plant stickers or seeds, may become lodged in the cat’s ear and cause an ear infection to develop.
A typical course of antibiotics for treating an ear infection can be as brief as five to seven days or as long as several months. In many cases, the ears may start looking better after only a few applications of medication or after only a few doses of oral medication. However, it is advised to give all medications as directed for the full course of treatment. Your veterinarian may recommend recheck exams during the course of treatment to monitor how well the condition is responding to therapy. Notify your veterinarian right away if your pet’s ears begin to look worse, if the problem seems to return after treatment is completed, or if other signs of illness are observed.
