You said you bought Butler NutriSentials Lean Treats as a treat for your pets. While the corn and fructose syrup are not good for your ferret, Propylene Glycol, is found in anti-freeze, and a lot of products from lipstick to deodorant to keepthemt soft. The manufacture says it is a small amount. Won't hurt you, ??? That stuff is lethal, and I also refuse to pay for chicken by-products now that I know what they are, claws, beaks, and feathers. Beef products contain hair and hoofs. If I knowingly purchase those products, I am saving the manufacture the price to haul his refuse away. Marilyn [Posted in FML issue 4899]
