Moma Cat looks a little startled! Maybe it's because one of the kitties is playing with the curtain!
This could be made into interesting ephemera by printing it out on card stock and cutting around the outline of the kitties.
You wouldn't need to cut the whole shape of the cats out; just cut enough to get the
shape of the heads and ears of mom and the kitten on the right.
