Works For My Cat!
My cat was diagnosed with Megacolon about 10 years ago. I spent several YEARS trying to regulate his condition using different foods, adding pureed pumpkin to his food, and giving him two different prescription medications (lactulose and a compounded prescription of Cisapride). All of those methods worked fairly well, but he truly didn't become "regular" until I introduced this into his daily regimen. I believe that this product has made a significant difference in his quality of life. The only problem I have had is availability - PetSmart carries it, but are so sporadic in maintaining stock of it that it finally dawned on me to go straight to the source - GNC. While PetSmart is often cheaper with BOGO sales and their PetPerks rewards program, I would rather pay a little more and have a steady supply available and shipped directly to my door. This is a great product that treats my cat's chronic issue very well and I am extremely grateful to be able to purchase it so quickly and easily from GNC.
