Yes, the kittens are at a stage now, where at least you'll have 3-4 weeks to rest your foot, get caught up on much needed rest, and do something for YOURSELF!!! After the 4 week mark, and they begin to run around and terrorize Skittles and everyone else, then I don't know what to tell you.
Can't wait to see them in a few hours. I saw a bit of lighter gray in the first pictures...awww!!! You did end up with some variety, and like a said before, a couple of darker tabbies!
Now you might not have to worry about telling them apart! They did all look a bit different from one another!
