Zoo staff have found that carcass-fed carnivores are calmer than those fed processed food
A few years ago, I attended a biannual convention of zoo nutritionists in Oklahoma for the book I was writing. Hanging out one night at the hotel bar with a group from around the United States, we got to talking about a practice in some European zoos that sounded shocking. It was called carcass-feeding, and like most Americans, I had never heard of it. This was long before the story of Marius, the giraffe fed to lions last Sunday at the Copenhagen Zoo, put carcass-feeding in the national headlines.
