I was very skeptical when ordering from a company I knew nothing of. And the product (Advocate) was so much less than (Advantage) both made by Bayer. I ordered the product and received in 10 days. This was for a stray cat that was decimated by fleas and worms. I didnt think she would make it. I gave the flea medicine to her. Wow..she is thriving and gaining weight. THANK YOU..Petbucket..for the great service..and something I can afford. And most of all Thank you from the Stray cat. You saved her life. Debbie S.
