What is the state of Viverridae in Captivity? I am also including Madagascar predators because they are effectively in the same group when it comes to zoos. These are some of the least well known mammals, and I am very fascinated by them. Other than the Binturong, which at least in the US is fairly common, how are the other species both in North America and around the world? Should better breeding programs be developed, and are some of these species at risk of being extinct?
