If there’s anything we’ve learned from internet memes, it’s that people love cute animals. Here’s a trove of adorable, candid photographs that capture moments of warmth between interspecies friends. Like a boar piglet (Elsa) and a Bengal cat (Leopold), friends who may appear to have little in common, but who each love the simple joys of running in the grass—and doing it together is all the sweeter. In an adorable mini format, perfect for a locker or cubicle, each photo is accompanied by a true story about the featured friends. Inspired by Jennifer S. Holland’s New York Times bestselling book with 920,000 copies in print.
