A silhouetted black cat peers over the edge of an open book against a soft sage green background, its fluffy tail curled dramatically along the spine. Bold white lettering across the book's cover reads "HOW TO TRAIN YOUR HUMAN" in confident capitals, creating a witty visual pun that flips the common pet-training narrative on its head. 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.
