Humans have to envy the cat’s
jumping ability, for the cat can jump six times her own length. (And that’s from a still position, not a running leap.) This comes from the same powerful but fast-tiring
muscle cells that enable the cat to sprint swiftly. The same muscles are involved in the classic pounce: using the hind
legs to spring forward, arching her back, then landing with her front paws on the
prey.
