BACK:
Your cat's back is marked by larger bones along the middle to support the weight of the torso. Muscles along the back are strong to help carry heavy prey over long distances if necessary.
BACK LEGS:
Your cat's back legs can only move backward and forward. The "knee" is the opposite of the "elbow" on front legs. They work together to give your cat a unique ability to spring and pounce.
FRONT LEGS:
Unlike the back legs, your cat's front legs can not only move forward and backward, but also rotate a bit so the underside of paws can be turned toward the face. This lets your cat clean and wash effectively.
PAWS:
Paws are so long that your cat actually walks more on its "fingers" supported by sensitive, dense pads. Claws can be retracted.
