This is a page on the anatomy of a cat’s claw written for children or people who like plain English. A few of the words are from the science of biology.
“Nails” are what some animal doctors (vets) call the claws of a cat.
This makes claws sound as if they are like the nails of a person.
It is wrong to do this because claws are different to nails, except for one thing. A person’s nails and the hard bit of a cat’s claws are made of the same stuff. It is called “keratin”, which is not a living substance.
There is also a softer, living, bit in the middle of a cat’s claw that is called “live dermis”.
Did you know that the spiky bits on a cat’s tongue, which are called “papillae”, are made of keratin too?
The nails of a person don’t do much but the claws of a cat do a lot. They are very important to a cat. These are the things claws are used for:
A person’s nail is attached to the skin of the finger. A cat’s claw grows out of the last bone of the cat’s toe. This is important. The cat’s claw is completely fixed to the toe. It is part of the bone of the toe and cannot be removed. It has to be firmly fixed like this because it is used so much and pulled so much. It has to be very strong.
When a cat is not using her claws they are “retracted”. This means that the claw is pulled into the cat’s toe by a muscle and a tendon so you can hardly see it. This is the normal position for the claw. A “tendon” is tough stuff that connects muscle to bone.
Some wild cats don’t retract their claws so much because they need them out a lot to get a grip on the ground for fast running. The cheetah does this.
As a cat walks on his toes, claws gets worn down when used, such as walking on rough tracks and so on. Indoor cats don’t usually get a chance to wear down their claws so the cat’s owner should trim them. This is good for the cat and for the person.
If a person likes cats they should learn to like a cat’s claws because they are an important part of the cat and they affect how the cat behaves.
