Research overview: digitigrade posture and its locomotor consequences in felids

Cats walk on their toes, a digitigrade posture that lengthens the effective limb and changes the geometry of force transmission. This overview reviews how toe-walking affects stride length, speed potential, shock absorption, and the silent footfalls used in stalking. The arrangement keeps the heel and wrist elevated and shifts loading onto padded toes, contributing to both cushioning and the ability to accelerate. Researchers connect digitigrady to limb-segment proportions, tendon arrangement, and comparative locomotor performance across mammalian foot postures. Understanding it matters because foot posture is a deep anatomical choice that constrains and enables much of felid movement, from the quiet approach of a stalk to the rapid limb cycling of a sprint, and it situates cats among the cursorial and ambush predators of the carnivore radiation.
