We have not introduced them to neither yet, but Sally knows they are here. Everytime she sees them, she starts growling. Lade knows too, she saw them once. She is not angry that they are here, but the kittens are scared of her. We're gunna take them out in the cat carrier on Saturday, and let Sally look at them. I hope Sally will learn to like them, or at least tolerate them being in the house.
