When I went to the zoo this weekend, I had the pleasure of meeting this cool guy in the Big Cats enclosure. He or she was about as big as a large golden retriever and just as friendly. He walked back and forth between viewing stations, looking at and posing for visitors. He or she seemed to especially like those with cameras. For those kneeling or kids in strollers, he or she would come to the glass and sit down, making eye contact with the visitor, and sometimes tilting its head.
