Cat
The domestic cat achieves remarkable velocity when sufficiently motivated. Sprint speeds reach 30 miles per hour in short bursts, with acceleration from standstill to maximum velocity occurring within seconds. This performance places cats among the faster domestic animals, exceeded only by certain dog breeds specifically bred for racing.
However, cats deploy this speed sparingly, preferring to conserve energy through extended periods of absolute stillness. The average cat spends approximately 70% of its existence sleeping, treating rapid movement as an emergency protocol rather than standard operating procedure. When speed does manifest, it typically arrives without warning, often at 3 AM, involving enthusiastic sprints across sleeping human faces.
Chameleon
The chameleon operates on an entirely different temporal scale. Locomotion occurs at speeds generously described as glacial, with movement so deliberate that predators frequently fail to register it as movement at all. This apparent deficiency serves strategic purposes, as stillness combined with colour adaptation renders the chameleon effectively invisible to threats.
The exception to this deliberate pace involves the tongue. Chameleon tongue projection achieves acceleration of 41 Gs, launching the muscular hydrostatic apparatus from mouth to prey in approximately 20 milliseconds. This represents one of the fastest movements in the animal kingdom, a fact that proves surprising given the creature's otherwise contemplative approach to existence.
