Researches in the United Kingdom have found a purr-fect way for you to communicate with your cat. A recent study published in the online journal Scientific Reports found that cats will appear friendlier and more approachable to humans who use slow-blinking, eye-narrowing facial expressions, which psychologists at the Universities of Portsmouth and Sussex referred to as a "cat smile." Sorry researchers. That "cat smile" is actually a smirk. Cats don't want to communicate, they want to give orders that are instantly obeyed. We don't have PhD.s but we do have three cats.
