The only distributors of their products on the west coast are TJ, ensenada, and rosarita. Most cruises stop in ensenada, so try their. However, just becuase someone is not on their distribution list does not mean you will not be abloe to find it in those cities. When you are in Mazatlan jump in a taxi (they are golf carts) and ask them to take you to a vet. They will know exactly what you want and take you there.
