Animals, though driven by survival, often exhibit behaviors that resemble hobbies. Birds, for instance, enjoy singing intricate songs, not just for mating but seemingly for pleasure. Dolphins are known for their playful nature, riding waves and tossing objects for fun. Cats may "hunt" toys, mimicking their wild instincts, while dogs love fetch, a game that reflects their natural retrieval instincts. Even primates engage in playful wrestling or tool use. These activities show animals engaging in fun, beyond necessity, much like human hobbies.
