Why can't humans jump as high as cats?

Humans can't jump as high as cats primarily due to differences in muscle composition and biomechanics. Cats have a higher proportion of fast-twitch muscle fibers, which provide explosive strength for powerful jumps. Additionally, their flexible spine and specialized leg structure allow for greater leverage and agility during jumping. In contrast, human anatomy is optimized for endurance and bipedal locomotion rather than vertical leaps.
