Actually, Their cuteness is starting to wear off a little with Gidget. Their little teeth and claws are starting to hurt when they grab tails and bite toes, so she's actually snapped at them a couple times. Not hard, She's still careful, but I try to keep them from testing her boundaries. A little's not bad... it's good for them to learn a little caution where dogs are concerned.
I gotta say, that the mothering-instinct thing that kicked in for Gidget with regard to those kittens, is really quite remarkable.
