Jennifer S. Holland
In Unlikely Friendships: 47 Remarkable Stories from the Animal Kingdom, Jennifer S. Holland compiles a collection of examples in which animals make friends with creatures outside their own species. Examples include a leopard with a cow, a dog with a piglet, an orangutan with a kitten, and a macaque with a dove. Each example comes with a short introduction documenting the location where the friendship took place, and each comes with heartwarming photographs of interspecies cuddling.
A quick, easy, and enjoyable read.
