We are Chocolate Moose & Mickey Moose,  Our nice owner bought this great food for us.  We love it very much, I have gained 5 lbs. because I eat all of Mickey's food when he isn't looking!  Our skin and fur is much better now too.  :)

Ex Input:
Fiber one products actually don't have real fiber.  They contain inulin (from chicory root) which is technically fiber because the body can't digest it.  Unfortunately fiber is defined by anything that can't be broken down easily.  These products do not contain REAL fiber. (The real fiber usually found in whole grain breads and bran cereals) So if it says "chicory root" or "inulin" in the ingredients, you can be sure you aren't eating the fiber your body can actually use.  So if you want lots of sugar and fat without fiber, this product is for you.
