Can animals keep other animals as pets? And if so, what does that mean? Many scholars claim that pet keeping among pets only happens in captivity and would never happen in the wild, while others are not so sure. When it does happen that an animal adopts another animal as a pet or surrogate child, there's no doubt that there is a level of affection and care there that seems awfully familiar to us as pet keepers ourselves. In this video from 2008, a monkey in Bali appears to have adopted a kitten as a pet. The kitten, at least in the video, seems not quite so sure about his new circumstances!
