This is usually measured in the Mohs scale of mineral hardness.
It measures 1-10, 1 being the softest, 10 the hardest.
Some examples of minerals classed 1-10:
1:Talc
2:Gypsum
3:Calcite
4:Flourite
5:Apatite
6:Orthoclase Feldspar
7:Quartz
8:Topaz
9:Corundum

This dog needs regular exersize. This will discontinue the nervous chewing and scratching.
One could purchase a used cat scratching post at a flea market, yard sale, or a swap meet. One could also check the classified advertisements in their local newspaper.
Cats see furniture as a scratching post, so, if you want to stop this behavior put more scratching posts, and pads in your house. If they still choose your furniture over the scratching post, try sprinkling the scratching posts with catnip.
The Mohs scale of mineral hardness measures the scratchability of minerals.

A mineral's resistance to being scratched (or when a force is applied) is called its hardness.There are different measurements of hardness: scratch hardness, indentation hardness, and rebound hardness. A material's hardness depends on ductility, elastic stiffness, plasticity, strain, strength, toughness, viscoelasticity, and viscosity.
