This month we're celebrating love in the animal kingdom, whether between pairs, siblings or friends. Sometimes the feelings we place onto these animals are our own, however there is no doubt that real bonds of affection can also exist between animals. We've put together a gallery of some our favourite images of pairs of animals showing closeness, friendship and love in wildlife.
