Our cat has had chronic diarrhea for several months and all treatments we tried nothing--prescription, OTC, herbal, yogurts. All the tests were inconclusive, so we were afraid this was going to be a permanent part of life. Our vet suggested we try this product, and not only does the cat love to eat them as a treat (!), we had immediate results. It has been 1 month without diarrhea. I am thrilled that we finally found something that worked, and our cat is back to his former self--happy and healthy.
