While pet food may not be uniquely vulnerable to contaminants, however, cats and dogs themselves may be more sensitive to them. Our pets are usually a lot smaller than we are, and they eat the same thing day after day. "Because we eat a lot of different foods, toxins that come in are diluted," Hofve says. "If we ate one thing all the time like most pets do, we'd be in a lot more trouble. Variety really is the spice of life, and our pets should eat variety too."
I think this is why I'm interested in supplementing my dog's kibble with some homemade (but not necessarily raw) foods. Anyone with a good (and simple!) recipe or two, please share!
