Show the list

Front half 16

  1. Skull The bones of the head. A cat has a short face, and each eye sits in a large socket.
  2. Mandible The lower jaw, made of two halves. It holds the lower teeth and hinges on the skull.
  3. Canine teeth One large, sharply pointed, slightly curved tooth on each side of each jaw, set apart from the small front teeth.
  4. Cervical vertebrae The seven vertebrae of the neck. They carry no ribs.
  5. Thoracic vertebrae The thirteen vertebrae of the chest. Each one carries a pair of ribs.
  6. Ribs Thirteen pairs. The first nine pairs are joined to the breastbone by cartilage.
  7. Sternum The breastbone: a chain of eight small bones along the underside of the chest.
  8. Scapula The shoulder blade: a flat, three-cornered bone with a ridge, the spine, down its outer side.
  9. Clavicle The collarbone. In a cat it is a small, slender, curved rod held in the muscles in front of the shoulder.
  10. Humerus The bone of the upper foreleg, from the shoulder blade to the elbow.
  11. Radius The front bone of the forearm, from the elbow to the wrist.
  12. Ulna The rear bone of the forearm. Its top end sticks up behind the elbow.
  13. Carpals The small bones of the wrist, in two rows. A cat stands with its wrist off the ground.
  14. Metacarpals Five bones between the wrist and the toes: four long ones and a short one for the first toe.
  15. Phalanges The toe bones. A cat walks on its toes.
  16. Distal phalanges The last bone of each toe, shaped to carry the claw. A springy ligament keeps it rolled back over the bone behind it, so the claw stays off the ground.

Rear half 11

  1. Lumbar vertebrae The seven vertebrae of the loins. They are larger and longer than the chest vertebrae.
  2. Sacrum Three vertebrae that join into one bone as the cat grows up. It holds the two hip bones.
  3. Caudal vertebrae The vertebrae of the tail: twenty or so, and fewer in short-tailed cats. They carry no ribs.
  4. Pelvis Each hip bone is three bones joined into one: the ilium, the ischium and the pubis.
  5. Femur The thigh bone, from the hip joint to the knee.
  6. Patella The kneecap: a small, flat bone that covers the front of the knee joint.
  7. Tibia The larger of the two bones of the lower leg.
  8. Fibula The much more slender bone of the lower leg, on the outer side of the tibia.
  9. Tarsals The seven bones of the ankle, which a cat carries off the ground.
  10. Calcaneus The heel bone, the longest of the tarsals.
  11. Metatarsals Four long bones between the ankle and the toes, with only a stub for the first toe.

How it works

Here is a cat skeleton labeled from the left side, drawn inside the outline of a standing cat with its tail up. The front half and the rear half are shown one at a time.

Read the full guide

Two halves of one cat

First comes the front half, names showing: the skull and teeth, the neck, the chest, the collarbone and the front leg down to the claws. The rear half has the loins, the hip bone, the hind leg and the tail. Tap any name for a line about that bone. Quiz me hides the names for the cat skeleton anatomy quiz.

What to look for on a cat

The skull is short and round. A small collarbone floats in the shoulder muscles. The last bone of every toe is rolled back, which keeps the claw clear of the ground. The loin vertebrae are long, and the tail is a chain of small vertebrae.

  • A cat stands on its toes: the first joint above the front paw is the wrist, not the elbow.
  • Chest vertebrae carry ribs; the longer loin vertebrae behind them carry none.

Questions and answers

How many bones does a cat have?

One anatomy text counts 230 to 247, leaving out the small bones that form inside tendons. The number is lower in an old cat than in a kitten, because some bones that start out separate join together.

Do cats have collarbones?

Yes, small ones. A cat's clavicle is a slender, curved rod of bone held in the muscles in front of the shoulder. It is not joined bone to bone with the rest of the skeleton.

How many vertebrae does a cat have?

Seven in the neck, thirteen in the chest and seven in the loins, then three that join into the sacrum. The tail adds twenty or so more, and fewer in short-tailed cats.

How do a cat's claws pull back?

Each claw grows on the last bone of a toe. A springy ligament keeps that bone rolled back over the one behind it, so the claw rests off the ground. A tendon under the toe pulls it down and out.
