Rare old book recommended by an old zoo (declaring it to be "maybe the best resource on zoophilia" or something to that effect). Allegedly it was written by a criminologist who spent decades researching the topic. Here is a machine translation to english for the benefit of the zoo community. It's a very unpolished translation, but it's at least readable; still, enjoy it for what it is, and I hope it'll bring some luck to you.
