Rated 5 out of 5 by Amazing! I switched over to this by recommendation from my vet. First off it arrived so fast...in one day!! Holy cow! Secondly, once it kicked in the fleas were just FALLING off!!! I was so glad to find a 6 pack for only $53, it covered one month for my cats and my ferret. This is definitely something I would continue to use. September 3, 2016
