Six cartoon cats progress from thin to increasingly rotund across a rainbow gradient scale, each illustration rendered in warm brown tones with simple, expressive proportions and playful postures. The chart mimics clinical measurement aesthetics while celebrating feline weight gain with bright color blocks ranging from green through yellow, orange, and red, creating humor through the contrast between scientific presentation and silly subject matter. Printed to order on a soft, absorbent mat with a no-slip backing, ready underfoot the moment you step out. The kind of art you don't expect on a bathroom floor.
