Take the heartbreakingly angelic goodness of a seeing-eye animal, add a dash of inter-species friendship, and you've got a recipe for tears. "Cashew, a 14 year old Labrador Retriever owned by Terry Burns in Middleburg, Pennsylvania, is blind and deaf. Her best friend is a red tabby cat named Libby. Libby has become Cashew's seeing-eye cat. She guides Cashew around obstacles, leads her to the food dish and even sleeps next to her every night." [Pandecats]
