Notice that the kittensâ ears are just beginning to unfold, though their eyes remain closed. Their sense of smell, hearing, and taste are slowly starting to develop. Tweed is only three days old. After almost a week, the kittens begin to wiggle around on their own a little bit and their eyes start to open.
Kittens are born deaf and blind. They also are born without teeth and cannot crawl and walk. But not for long ..... Usual kitten development includes kittens' eyes most commonly opening between 7 to 10 days of age. Do not attempt to pry the kitten's eyes open before this. Let the eyes open when they are ready.
