The average cat needs about an ounce of water per pound of body weight daily, adding up to about two quarts of water per week. A cat’s meow is usually not directed at another cat, but at a human. To communicate with other cats, they will usually hiss, purr and spit. Landing on all fours is something typical to cats thanks to the help of their eyes and special balance organs in their inner ear. These tools help them straighten themselves in the air and land upright on the ground. Source: Animal Planet
