Do animals cuddle?
Yes, they do! Like us, some animals use physical contact to strengthen bonds between them and to share warmth and safety – for the purpose of your question, we can call this ‘cuddling’. Cuddling is mostly expressed in mammals, the creatures that enjoy tactile behaviour and have hair follicles. Some experiments in mice showed that when these hair follicles were stimulated it brought about a pleasure response, which goes some way to explaining why we humans enjoy touch and why our pets love to be fussed over. In the natural world touch is part of social behaviour. Lions in a pride will lie down together and nuzzle one another; wolves in a pack will all bunch together when they rest; and animals that hibernate will often come together to share body heat. This provides a closeness and safety in numbers.
