The rabbit might be refusing pellets because it prefers hay or greens, which are key to its natural diet. It could be full, picky, or just not in the mood, especially if the pellets aren't fresh or the bowl isn't clean. Health issues like dental problems or gut stasis are possible but less likely given the video's playful tone. Rabbits are grazers and may skip pellets if they've eaten enough hay. If refusal persists, a vet check is wise, but this seems like a normal behavioral choice.
