About 10 years ago, my dog was loaded with fleas. They were all over the house and everyone was scratching...ugh. I read something quite interesting; give the animal a small piece of brewers yeast and just watch. To my amazement, the very next day, I watched the fleas jump from the dog, just like magic. It worked!

Now we have a cat and ditto..and sure enough, the fleas jump off...I think the brewers yeast causes a Body Odor and the insects bail out...what else..We break the little pill in two and give it daily...walla....no more scratching....peace
