"Fillers," a commonly used scary word to warn pet owners away from one product, and into the arms of another, but do we really know what that word means? What exactly IS a filler anyway?

Nicole and Jez talk about what a filler ingredient actually is, and why some ingredients that commonly get the "filler" blame are unjustly slandered. Dr Nicole Su is a veterinarian, Jez Watts is a comedian-biotechnologist, and together they discuss commonly misunderstood topics in the pet and vet world. They live with three rabbits who are their children.
