Every kitten is born wet and helpless resembling anything but a cat.  Newborn kittens are generally less than 5 inches long and weighing only a few ounces at birth.  Their ears are tightly folded over and eyes squeezed shut.  Every newborn kitten is born unable to see, hear or walk.  Kittens are born with the righting reflex and heat receptors on its head to help it find it's mom and a tiny little voice for making distress signals and the ability to purr.  At this point, momma cat herself provides the only source of food, warmth, cleaning and grooming, protector and sole care giver.  At about a week old the kittens will start to blink their eyes a bit, however, they won't fully open for a few weeks yet.  All kittens are born with mesmerizing blue eyes.  At about two weeks kittens begin hear. At two weeks to about a month their teeth begin to come in and they become more coordinated and begin to move around, although not too graceful at this point.
