They are all wearing clothes, with the largest cat wearing a blue suit and tie, the second largest wearing a pink dress, the third largest wearing a blue shirt and tie, and the smallest wearing a red dress. The doctor, who is blue, is wearing a white coat and a blue hat with a red cross. The background is a green wall with a whiteboard and a poster. The cats are standing on a blue examination table, and the doctor is holding a stethoscope. The video is in color and has a playful tone.
