So Far this seems to be doing the job. My cat hates it and she shakes her head but because it's a gel it tens to stay in somewhat. We will see if it totally gets rid of the mites.
It did not bother him so much like everything else I tried, and it seems to be working well. You must follow the instructions carefully. I even removed the label so I could warm it up a bit in some hot water as I had read some place...it is better to have the right body temperature if it goes into the ear.
