If you look at the box carefully it says 60mg/ml on Revolution box. This doesn't mean each tube contains 60mg Selamectin. It rather means the formula is 60mg Selamectin for each ml. Each Revolution tube contains 0.75 ml liquid not 1 ml. Therefore there is 45mg Selamectin in each tube. In contras due to regulations in Europe and some other markets, Stronghold displays what is in tube (45 mg selamectin in 0.75 ml tube) rather than the formula ( 60mg per ml). Both products contains 45 mg active ingredient in 0.75 ml liquid in each tube.

If your dogs is under 5lb, you should use Stronghold Pink (Stronghold Puppy and Kittens under 5lbs). If he/she is over 5lb you should use next level which is Stronghold Violet Dogs 5-10lbs.

Yes it would be the same unless the manufacturer increases its prices which they do once every few years. In that case we only add the difference to your price and we guarantee that we still be the cheapest in the market. You can also cancel your recurring order anytime you would like.

Stronghold/Revolution treats mange for dogs, but this is not the case for cats. So Revolution/Stronghold for cats doesn't treat mange.

Stronghold prevent heartworms but it doesn't treat it. So if you have suspicion that your cat has heartworm, it would be good idea to get your cat tested. If she/he has heartworm you would need a different medicine to treat it. This product wouldn't have any extra side effect if they have heartworms, but it won't treat it either.
