I recently ordered Revolution for my kitties from this company. The box came from Australia, which made me a little apprehensive but it looked legit, so I didn't worry too much. That is, until I opened the box and noticed that the dosage marked on the pipettes was not the same as the dosage on the box. The box was marked as .45 mg of Selamectin. The pipettes were marked as .60 mg. This is a big difference when you're talking about dosing a 10 lb cat. I would not recommend ordering from this company. If you care about your pets, take them to a vet, pay the $50 for a check up and order from a verified source with a prescription. Canada vet may be a little cheaper than other sites, but it is not safe.
