Pet Ultimates Probiotics for Cats - 20 Species - Stops Diarrhea & Vomiting, Cuts Litterbox Smell DON'T BE FOOLED - Other probiotics contain just one species and only a hundred million CFUs. But each serving of ours contains at least five billion CFUs of twenty different kinds of health-supporting probiotic bacteria -- that's fifty times the CFUs of the "name brand." (And then we give you four times as many servings!) NONE OF THE BAD STUFF - Don't fall for Chinese-made cat probiotics or products using sugar, grain maltodextrins or even "animal digest" (look it up) as their base. We spend more to bring you a product free of cheap fillers. 100% MADE IN USA - Our product is made in America in a GMP-certified facility. Don't take chances with cat probiotics that were made overseas. TWENTY SPECIES - Most of our competitors just slap a label on some random manufacturer's off the shelf, single-species product. But we custom-formulate our probiotic with twenty carefully selected species for maximum effectiveness. Then we manufacture it in small batches so it's fresh. THE BEST GUARANTEE  If within two weeks you don't experience what in your opinion is an extraordinary improvement in your cat's health, contact us for an immediate, polite & cheerful refund of every penny. (And you don't have to send back the unused portion.) You must be delighted or it's free
