Cat
The domestic cat achieves burst velocities of 30 miles per hour under optimal conditions, a capability inherited from wild ancestors who required such performance for prey capture. This speed manifests in short explosive movements lasting mere seconds before the cat returns to its baseline state of profound immobility.
Reaction time proves equally impressive. Feline reflexes operate at approximately 20 to 70 milliseconds, enabling responses to stimuli before human observers have registered the event occurring. This combination of explosive acceleration and instantaneous reaction creates a predator of remarkable efficiency, when the cat can be bothered to engage.
Duck
Duck locomotion presents a study in versatility rather than raw velocity. On land, the average duck waddles at a measured 4 to 6 miles per hour, a pace suggesting neither urgency nor particular destination. This terrestrial performance would embarrass most creatures claiming any predatory heritage whatsoever.
In water, however, the duck transforms entirely. Swimming speeds reach 6 miles per hour with diving capabilities extending to considerable depths. Flight velocities in migratory species exceed 50 miles per hour, though domestic ducks have largely traded this capability for increased body mass and sedentary contentment. The duck's speed profile varies dramatically by medium, complicating direct comparison.
