About Kenny: A quick note on the banner photo—that is Kenny, a famous rescue white tiger. He had a rough start due to severe real-life inbreeding deformities, but he was rescued in 2000 by Turpentine Creek Wildlife Refuge. The keepers described him as a happy, playful soul who spent his final years living comfortably and well-loved.
