It's getting to be the time I order this for my five cats and one dog. Since I'll keep them on it for the better part of the year till November, could anyone please tell me online companies you like and have had success with..ie, quick shipping and excellent pricing. With six pets, it can get pricey. A few years ago I had a bad experience with one company. Never received their product but they insisted I did. I'm always afraid of getting bogus products too.
