![]() ![]() To protract (extend) the claw, the cat uses the deep digital flexor muscle which overpowers the elasticity of the dorsal elastic ligaments. The distal phalanx which contains the claw has two dorsal elastic ligaments which keep the claw retracted and sheathed within the skin of the paw which reduces wear and tear on the claws. Structures that produce the claw include the matrix, proximal nail fold (ungual fold), eponychium, paronychium and the hyponychium, which are collectively referred to as the perionychium. As the claw grows, the outer layer sheds which expose a sharp new claw underneath. Claws are composed of layers of keratinised (reinforced with keratin) dead cells. The claw ( unguis) is located on the distal part of the toe and is attached to the final toe bone. Jake, an orange male from Ontario, Canada holds the world record for the largest number of toes at a whopping 28. Some cats (known as polydactyls ) have more than the normal number of toes and claws. The fifth toe is the dewclaw, which is located on the inner side of the foot and does not make contact with the ground. Cats have four toes on each hindfoot and five toes on the front feet.

Beauty or Function?įor a long time, dewclaws were assumed to be vestigial and useless. Some dewclaws are unattached by bone, though, particularly double dewclaws or those found on the rear paws. Most dewclaws are attached to the rest of the paw, much like your thumb is attached to your hand. If you gently grab the dewclaw and wiggle, you will notice that the dewclaw is attached to bone. If your pet has their dewclaws, you can also investigate a little further. Even if your dog does not have a visible appendage where the thumb ought to be, often on closer inspection you will be able to identify a scar where one once was.
