Forget Sylvester and Tweety. This cat-and-bird duo defies all the odds when it comes to feline-avian relations. After Ann and Wally Collito, a couple from Massachusetts, found a kitten abandoned in their yard, they weren't sure what to do with it. They were surprised to find, though, that Cassie (what they eventually named the cat) already had a guardian of his own: Moses the crow. The Collitos observed and videotaped the pair over an eight-month period and noticed that Moses was caring for Cassie by feeding the cat worms, leading him to water and playing with him regularly.
