The order for Revolution flea, tick, ear mite and wormer (perfect combo) came in good time with no problems. It is so easy to use and once the cat is snuck up on and caught, is quick to apply. The youngest cat came to us from a farm and had ear mites. He is now four years old and even though he has been treated for mites, his ears were sensitive until I used Revolution a couple of months. He is doing well, now. We have three cats and none have ill effects from Revolution. I will buy from you as long as I have pets! I appreciate how easy it is to order and the quick shipping time. I am in Kansas, USA. and it takes a couple of weeks for the package to arrive, so it is simply a timing issue for when to order and no problems here. Thank you!
