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. Built from double-wall stainless steel and made to order, holding 20 ounces with a snap-on lid, a standard-cup-holder fit, and wraparound artwork. Your commute carrying original art instead of another branded tumbler.
