A domestic cat's retractable claw in protracted position. A claw is a curved, pointed appendage found at the end of a toe or finger in most amniotes (mammals, reptiles, birds). Some invertebrates such as beetles and spiders have somewhat similar fine, hooked structures at the end of the leg or tarsus for gripping a surface as they walk.
A cat's claw. Like nearly all members of the family Felidae, cats have protractable claws. In their normal, relaxed position, the claws are sheathed with the skin and fur around the toe pads. This keeps the claws sharp by preventing wear from contact with the ground and allows the silent stalking of prey.
Kittens are born with their eyes and ears shut and the claws not retractable (unable to be drawn inside); the coat resembles that of adults, but the abdomen is spotted. Eyes open by ten days, but it takes longer for the vision to become normal. The ears become erect and the claws become retractable by the third or the fourth week.
The claws are guarded by cutaneous sheaths, except in the Acinonyx. [12] The plantar pads of both fore and hind feet form compact three-lobed cushions. [13] They actively protract the claws by contracting muscles in the toe, [8] and they passively retract them. The dewclaws are expanded but do not protract. [14]
It turns out that a cat's claws are shaped like fish hooks, which makes climbing up a tree, for example, very easy to do as their claws can easily grip the bark. Coming down, however, is not so ...
The cat exerts firm downward pressure with its paw, opening its toes to expose its claws, then closes its claws as it lifts its paw. The process takes place with alternate paws at intervals of one to two seconds. The cat may knead while sitting on its owner's lap, which may prove painful if the cat has sharp claws.
Members of the cat family – including domestic cats [9] and wild cats like the lion [10] – have dewclaws. Generally, a dewclaw grows on the inside of each front leg but not on either hind leg. [11] The dewclaw on cats is not vestigial. Wild felids use the dewclaw in hunting, where it provides an additional claw with which to catch and hold ...
Shed claw sheaths. Cats have protractible and retractable claws. [56] In their normal, relaxed position, the claws are sheathed with the skin and fur around the paw's toe pads. This keeps the claws sharp by preventing wear from contact with the ground and allows for the silent stalking of prey.
