My cat was shaking her head and scratching at the ears. She was to the vet a few weeks ago. The vet said she did not have ear mites. I decided to try zymox plus since the reviews were so good. I put it in her ears for 7 days as indicated. She is no longer pawing at the ears and scratching. I believe this has helped her tremendously. If you cat has any ear problems like mine did then try this. It is well worth the price for a product that actually works. I would and will buy this again. Also....countryside pet was very quick to ship this out.
