Cat hair on solid black.. imagine how much that would show up. How about a tea colored fabric or med. ivory since you are making a more primative style? Or if your set is six, five cats one mouse (or offer that as an option?) six cats or five and one mouse and make the mouse look worried. No smiles. They look like kitty ornies. . Put a crown on the mouse :) or bird. That would be cute. button eyes? ah heck they are fine the way they are. Messing with a good thing and all that.
