How it works: 

Revolution works by penetrating the skin and entering your pet's bloodstream. Concentrations of selamectin, the active ingredient, in the tissue and bloodstream prevent heartworm disease. Selamectin also redistributes into the skin from the bloodstream and kills adult fleas, American dog ticks, and ear mites, and prevents flea eggs from hatching. It is also an anthelmintic, which means it fights to expel parasitic worms. Parasites ingest the drug when they feed on the animal's blood. Revolution is safe for pregnant and lactating pets.

Great resource

I just love how cheap the Revolution is on here and you get extra doses as well. At first, I was concerned about the shipping but it always arrives in the US in less than 2 weeks, faster than when I order it from my online vet pharmacy. I am very happy I found this website.

Great product!

Not only is the product great, but so also is the customer service. I can't believe how quickly this arrived especially considering how far away you are. I have 5 cats who are inside cats. They never get fleas. Then one day we had a dog visitor - then there were fleas! I had tried natural products, but nothing worked. Then I ordered this Revolution and they fleas were gone in a couple days. Now I keep some on hand just in case it ever happens again. After having just one flea on myself, I couldn't imagine how miserable the cats were with several crawling around on them. The poor babies. Now I even treat the neighbor's outside cat. I can't believe how much less expense it is to buy it from Sierra Pets than to buy it here in the Unites States. That just shows the greed of the sellers here. Thank you Sierra Pets for making this product affordable to everyone!
