Commonly, BDSM fan comics deal with themes like trust, communication, and the negotiation of limits. They can showcase various forms of power exchange and sensory experiences. The art style might vary to enhance the mood and atmosphere.
Maybe they could be elements in a children's book or a game. For example, in a cartoonish game, the cat has to reach the cuckoo clock within a certain time to win. Or in a children's book, the cat dreams of a cuckoo clock in a cartoon world.
I have no clear idea. It could be a concept in a particular art form or perhaps related to a children's story. Without additional details, it's hard to determine the connection.
Often, such a scene in a cartoon could be purely for entertainment or to challenge conventional ideas. It might not have a deep, fixed meaning and could just be a creative visual element.
