I heard on the radio a few months ago about a food challenge. One of the DJ's said that she tried Purina One (they have different types and flavors) and gave a number for a free 3lb bag. I've been trying this for a while now. She said it is supposed to make your cat have more energy, make their fur softer and shinier and have less dry skin. I have the Toatl nutrition and can see a difference already! Oscar is more playful and his fur has less dander. Just wondering if anyone has tried this and wanted to know your story? Oh and if anyone wants the number for the free bag, PM me and let me know. Hope to hear some stories!
