BABY BLUES: Kittens are born with blue eyes. A cat’s permanent eye color develops by 10 to 12 weeks of age. 
USEFUL MUSTACHE: A cat’s whiskers have many nerve endings that serve as touch receptors that can initiate a blink response to protect the eyes. The sensitive whiskers also serve as a navigational aid in the dark and help detect the movement of prey. 
NIGHT STALKER: Cats are naturally nocturnal hunters with great night vision. Reflective membranes behind a feline's retina called the tapetum aid in maximizing available light during darkness. 
TRUE COLORS: Cats see the world similar to how a color-blind human does. They can see shades of blue and green, but they have a hard time distinguishing reddish tones. Different shades of red tones may appear greenish or bluish to a cat. 
MEMORY CHAMPS: Compared to dogs, cats have longer memory retention. Cats can recall information for about 16 hours—a dog’s recall lasts about 5 minutes.
