Like a graceful vase, a cat, even when motionless, seems to flow.

Will’s simile treats the cat as a work of art: like a well-proportioned vase, its form has an inherent harmony that reads as “movement” even in stillness. The paradox—motionless yet seeming to flow—captures the feline quality of poised potential energy, where balance, line, and musculature suggest readiness and grace rather than inertness. The remark also implies an aesthetic way of seeing animals: the cat is not merely observed behaviorally but appreciated formally, as shape, contour, and presence. In that sense, the quote is less about cats alone than about how elegance can be a property of form itself, independent of action.
