Kay - I'll bet soon that Sissy will be running and playing with him, and with all the energy that they both have, it will sound like a stampede running thru the house. Wolfy loves his kitty playmates, and Luke is just as rough and tumble as Wolfy is. This morning Wolfy got a little too rambunctious tho, and was trying to drag Luke around by his ear. Needless to say, Wolfy took a paw full of Luke's claws to his nose. They keep me laughing tho.
