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.
Skull
The cat skull is unusual among mammals in having very large eye sockets and a powerful and specialized jaw. : 35  Compared to other felines, domestic cats have narrowly spaced canine teeth, adapted to their preferred prey of small rodents. Muscles
Internal abdominal oblique
This muscles origin is the lumbodorsal fascia and ribs. Its insertion is at the pubis and linea alba (via aponeurosis), and its action is the compression of abdominal contents. It also laterally flexes and rotates the vertebral column. Transversus abdominis
This muscle is the innermost abdominal muscle. Its origin is the second sheet of the lumbodorsal fascia and the pelvic girdle and its insertion is the linea alba. Its action is the compression of the abdomen. Rectus abdominis
This muscle is under the extensive aponeurosis situated on the ventral surface of the cat. Its fibers are extremely longitudinal, on each side of the linea alba. It is also traversed by the inscriptiones tendinae, or what others called myosepta. Deltoid
The deltoid muscles lie just lateral to the trapezius muscles, originating from several fibers spanning the clavicle and scapula, converging to insert at the humerus. Anatomically, there are only two deltoids in the cat, the acromiodeltoid and the spinodeltoid. However, to conform to human anatomy standards, the clavobrachialis is now also considered a deltoid and is commonly referred to as the clavodeltoid. Acromiodeltoid
The acromiodeltoid is the shortest of the deltoid muscles. It lies lateral to (to the side of) the clavodeltoid, and in a more husky cat it can only be seen by lifting or reflecting the clavodeltoid.
