For all those touched by the stories in the bestselling book Unlikely Friendships, One Big Happy Family celebrates the intimacy and emotional connections of parenthood. Whether it's the border collie and the piglets, the cat and the ducklings, or even the golden retriever and the baby hippo, these are poignant, charming tales of animal moms and dads whose nurturing instinct overrides their species instinct. Filled with full-colour photographs, this book includes in-depth stories about animals that have reached out to save the lives of babies from other species and raise them as their own.
