Query: I couldn't believe the results

My cat and my dog were a mess. Both of them looking like in a constant itch, until I a friend recommended Bio-Coat. My cat is a very picky eater, and I couldn't believe that she love it so much. Now I have to put it on everything she eats. Shedding has stopped, even the musky smell. Whatever they put in that stuff it works. I knew that biotin is good for coat and skin, but I didn't expect results so drastic. I was under the impression that my cat and my dog are suppose to loose so much coat.
