I am very satisfied with the Stronghold for all my cats. I needed to have a better solution for treatment of my 2 colonies, inside and outside, that would stop breaking the bank! Enter PetBucket. My vet called me and told me it was time to come pick up my Resolution. It was powerful to say "No, I am now ordering Stronghold from PetBucket. She just sat there for a minute, totally surprised that I knew about it. She knew, but wasn't going to tell me. If ya'll need Resolution, switch over to Stronghold from PetBucket, and start saving your money!
