The kittens are doing well, eating, drinking, and pooping. I guess that is what kittens do. Two of them will let me pick them up and hold them, and pet them, without hissing or spitting. One (the white one--first captured alone) is still really wary, and so far, the best I can do with it is to reach my hand (ensconced in gloves) into the kennel and try to stroke it a bit.
A storm is brewing, so we will see how they handle that, though they obviously survived the last one in an old mailbox on the side of the road.
All I have to say after this week is thank goodness tomorrow is Friday!
