Query: Don't buy this

I've had cats for over 50 years as pets, and ear mite problems have occurred occasionally over the years. Other ear mite treatments I've used in the past seem to work fine. These don't do anything. Not only that they are expensive but the packaging is misleading. It says each tube has 100 drops. I got 40 out of the second tube (the only one I counted). Buy another brand.
