Hey Sukie.
Typically, kits open their eyes at approximately 4= weeks of age. Although,
some may vary in either direction, four and a half weeks tends to be the
norm. I have had kits open them later (my last two litters, one had eyes
open at 4= weeks, the other their eyes opened at 5= weeks) Personally,
I've never had any open sooner, but have heard of it happening.
Hope this helps :o)
