Revolution For Cats - 5.1 to 15 lbs.
This was the first time I ordered from Sierra Pet Meds but will definitely NOT be the last! The cost of the medication for my cats was considerably less than anything I could find here in the States. I'll admit, I was concerned that the product might not be equivalent to what is sold in the U.S., but that fear proved to be unfounded. The communication via e-mail was promptly answered and the item arrived in less time than it takes to get a parcel from point A to point B domestically. I highly recommend this company. Their products and service are A-1.
