At the top of the Cartoon Style image, Penblwydd hapus

Playful, funny cartoon scene in a bright, neon gym packed with energetic cats. Exaggerated proportions: big heads, big eyes, tiny bodies, chunky paws; thick black outlines and bold, saturated colors. Center stage: a determined tabby in a sweatband sprinting on a treadmill, legs a blur, tail forming a swoosh ribbon; goofy grin, tongue out, whiskers streaming. To the left, a chonky ginger cat bench-presses a barbell made of giant yarn balls, cheeks puffed, eyes crossed with effort. To the right, a sleek tuxedo cat does high-knee running drills on a mini indoor track, wearing tiny paw-print sneakers, ears pinned back in focus. In the background, a scratching-post squat rack, kettlebells shaped like fish, and balloons shaped like yarn balls. All cats wear tiny party hats for birthday vibes; confetti and spark bursts pop around them.

Style: playful Cartoon Style with 2D cel shading, shiny highlights, and bouncy shadows; palette of electric blue, neon pink, lime green, sunshine yellow, and purple accents. Whimsical motion lines, sweat droplets shaped like little paws, and dynamic, energetic poses. Low-angle, wide composition to amplify the action, full-bleed image.

Front text styling at the top: big, bubbly letters with a fun rainbow gradient fill and thick outline, nestled among confetti and starbursts.

Include one small caption only: at the bottom-right in a comic speech bubble from the sprinting cat, text: Cardio? More like CAT-dio!
