Cats talk with their eyes. Squinting their eyes however is a form of communication, sometimes blinking one eye at a time and much slower than a human’s blink. Ever noticed your cat look at you and slowly squint their eyes closed? That’s a sign of deep affection and you should return the gesture. Cats have rotating ears. Their ears can rotate in various degrees with even the capability of making one of their ears point backwards to listen. Their intuitive hearing can help make the cat a very successful hunter by pinpointing the exact location of their prey within three inches. Source: Victoria Swanson, Smart Living
