«We found that lemurs who were frequently observed by others while solving the task to retrieve the food received
more affiliative behaviors than they did before they learned,» said Kulahci, who is a postdoctoral researcher at University College Cork in Ireland.
«Both dogs and cats were reported to demand
more attention from their owners and / or display
affiliative behavior, as well as spend time seeking out the deceased pet's favorite spot,» noted the study article that appeared in Animals 2016, 6 (11).
