Oakland Zoo has a version of the Top Trumps cards with animals from the zoo. Not sure what the gameplay is like, but the cards are interesting. They use real photos and have categories like "Lifespan", "Group Size", "Poop Factor", "Weight", and "Threat Level".
I'll scan a copy and post if folks are interested in seeing one in more detail.
