I have a lifetime or two (ferret-wise) supply of Coat Guard shampoo form a company called Protec, a division of Protein Technology of Pleasant Hills, California. I originally bought this stuff for our dog because of his super sensitive skin, but decided to go back to a flea shampoo since fleas seem to be his primary problem. Anyway, it's expensive and I hate to buy some other expensive shampoo if this stuff is safe for ferrets. From the label, it sounds like it is. In fact, it even says "for all animals" and "for all animals with sensitive skin". But this is a California based company and theoretically Californians don't own ferrets. The label explicitly states that it's okay for cats. Here are the listed ingredients: wheat germ conditioners, coconut cleansers, sulfur, jajoba oil, natural ingredients, no fragrances or coloring. It all sound pretty safe to me, except maybe for the sulfur, and I've never heard of jajoba oil. I searched through the FAQ file for any reference to this company or its product; even the ingredients but didn't turn up anything. cobra [Posted in FML issue 1149]
