In the video, a brown and white puppy is seen sniffing and biting a cardboard box that has the words "BARK BOX" printed on it. The box is placed on a black mat, and a cat is lying on the floor behind the box, watching the puppy. The puppy is wearing a blue collar and appears to be curious about the box. The cat has a striped pattern on its fur and is mostly still, observing the puppy's actions.
