Cat’s muscles are as expected mainly made up of fast-twitch fatiguing cells – hence the cat’s speed (30 mph max for domestic cat and 64 mph for cheetah) and ability to jump up to six times its length. When sprinting a cat generates a lot of heat and pants within a short time. The slow-twitch muscles are used for slow stalking, almost slow motion walking when approaching prey.
Cats have flexible muscles and they are mainly attached to either side of the joints of bones to articulate them, which is achieved by the muscle contracting. Muscles often act against each other, e.g. one extending a limb and the other contracting it3. Muscles can only contract.
