Over the next couple of years, Brewer introduced into her program 23 cats from around the nearby Cascade range, that were believed by her to be born from naturally occurring matings between bobcats and domestic cats. She coined the term "Legend Cat" to refer to such cats and has since registered a trademark in the U.S. to limit the term to describe permitted outcrosses used in her breeding program. At the same time, other breeders in the U.S. were working with distinctly wild looking barn cats and collaborated with Brewer to establish a broad genetic base and to develop the foundation of today's Pixie-bob.
