The kittens are getting a bit more aware of their surroundings
One kitten, blue collar, is a right old hissypants and will have a conniption if you so much as look at him. Some of the others are more easygoing. It's a bit scary to be a kitten this small, you can't see, you can't hear, and when a big hand comes and scoops you up what else can you do but squeak and spit? That is, if you are awake. Of course a hissing kitten is about the least scary thing in the whole world, but they don't know that do they?
I can't remember who this is.
Speaking of blue collar, he has the teeniest chink of an eye open, the first of the bunch. Hello, baby!!!
