Its origin is via apoeurosis following the length of the mid-dorsal line, and its insertion is the dorsal portion of the last ribs. Its action is to depress and retracts the ribs during breathing. Intercostals
The intercostals are a set of muscles sandwiched among the ribs. They interconnect ribs, and are therefore the primary respiratory skeletal muscles. They are divided into the external and the internal subscapularis. The origin and insertion are in the ribs. The intercostals pull the ribs backwards or forwards. Caudofemoralis
The caudofemoralis is a muscle found in the pelvic limb. The Caudofemoralis acts to flex the tail laterally to its respective side when the pelvic limb is bearing weight. When the pelvic limb is lifted off the ground, contraction of the caudofemoralis causes the limb to abduct and the shank to extend by extending the hip joint. Pectoral
Pectoantebrachialis
Pectoantebrachialis muscle is just one-half-inch wide and is the most superficial in the pectoral muscles. Its origin is the manubrium of the sternum, and its insertion is in a flat tendon on the fascia of the proximal end of the ulna. Its action is to draw the forelimb towards the chest. There is no human equivalent. Pectoralis major
The pectoralis major, also called pectoralis superficialis, is a broad triangular portion of the pectoralis muscle which is immediately below the pectoantebrachialis. It is smaller than the pectoralis minor muscle. Its origin is the sternum and median ventral raphe, and its insertion is at the humerus. Its action is to draw the forelimb towards the chest.
A cats skin has the same color as the fur, but the color of the nose leather is probably dictated by a dedicated gene. Cats with white fur have skin susceptible to damage by ultraviolet light, which may cause cancer. Extra care is required when outside in the hot sun. Legs
Cats are digitigrades, which means that they walk on their toes just like dogs. The advantage of this is that cats (including other digitigrades) are more agile than other animals. This is because all animals usually have ground reaction forces (GRFs) at around two to three times their body weight per limb. Digitigrades have a higher GRF compared to other animals due to the increased weight on a smaller surface area, which would be about six times their body weight per limb.Toe tufts are commonly found on cats with medium to long coats. Clumps of fur that stick out at least 1–2 cm (0.39–0.79 in) beyond the paw pad can be considered tufts. In addition to soft paw pads, toe tufts help a cat to silently stalk its prey by muffling excess noise. However, outdoor cats tend to lose their toe tufts due to excessive abrasion on the rougher outdoor surfaces. This is in distinct contrast to indoor cats who spend most of their time walking on carpet or smooth floors. Cats are also able to walk very precisely. Adult cats walk with a "four-beat gait" meaning that each foot does not step on the same spot as each other.
