Milbemite Otic Solution is tough on ear mites but gentle enough for cats and kittens four weeks of age and older. Ear mites can spread from pet to pet through close contact, which can ultimately lead to uncomfortable symptoms like itchy ears, head shaking and ear inflammation. Milbemite Otic Solution is formulated to kill 99% of ear mites after just one application and should continue to work during the entire mite life cycle. Each purchase comes with two, easy-to-use tubes of Milbemite. **Proudly sourced directly from the manufacturer or their approved distributor. Guaranteed genuine and backed by the manufacturer.**
