Just found this, just passing it on.

Mepps asks all squirrel hunters to please recycle their squirrel tails. We have been buying the tails of fox, black and gray squirrels for more than three decades; they are used to dress the hooks of our spinners. Hundreds of other materials, both natural and synthetic, have been tested, and nothing else works as well. We will pay up to 26 cents each for tails, depending on quantity and quality. If you would like to exchange the tails for Mepps lures, their cash value is doubled.
