8.6/10 our score
- 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.
- EASY-TO-SERVE POWDER - Powder format is simple to administer with the included scoop.
