In 2015, we met Goliath, a young cow who was rescued from a dairy farm. He was nursed back to health with bottle-feeding, and he adopted a sibling: a Great Dane named Leonidas. His rescuers in California say Goliath started thinking he was a dog, too. When human Hannah Simpson couldn’t afford a horse of her own, she opted for a cow named Lilac. And Pusha the cat thought she was a squirrel mom after she formed her own little family with four baby squirrels in Crimea.
