7-weeks... 

5-weeks... 
getting pretty active, exploring everything, trying to escape, very curious about me, eating, drinking water, using litter pan,
running, climbing, playing with wand toys, wrestling more, and very very cute (despite being in what's called "ugly" fuzzies)
(Note:  all kittens are born with blue eyes, and true eye color won't develop until several months old.)

4-weeks... 
now walking, still a little bit unsteady but getting stronger, still suckling from mama, 
starting to play with toys, starting to wrestle with one another, starting to climb, curious about everything
