CATSMouse

A grey kitten walks toward the camera on a wooden floor, its mouth suddenly enlarged with a red, cartoonish effect as it opens wide, then returns to normal as it continues walking. The scene cuts to a dark-furred cat with a similar red mouth effect, then to a tabby kitten looking up from a person's lap, also with a red mouth effect, before cutting to a calico cat with a red mouth effect staring directly at the camera. The setting is a brightly lit indoor room with wooden floors and furniture.
