Create a photorealistic image of a chubby white cat performing a highly acrobatic routine on the vault during the Olympic gymnastics finals. The cat should be in mid-air, with its body twisted and spinning at high speed, showcasing its impressive athletic abilities. The background should feature a vibrant crowd, cheering loudly, with flashes of cameras capturing the moment. The lighting should emphasize the cat's fur and the dynamic motion of its performance, highlighting the contrast between its adorable, chubby appearance and its remarkable acrobatic skill. --ar 1:1 --niji 6
