The Great Irony of Cat Grooming is a universal law, as far as I have been able to ascertain, and it is one that I assert for all of the science and pet journals to pick up thusly:

“Those cats that are not really in need of grooming enjoy it, whereas those that really need it turn into hell spawn and spare no thought at shredding you into ribbons at the mere glint of a comb”

My two short haired cats (Keet and Ming) enjoy being combed. Missile, my long haired ratty cat, gets evil red glowing eyes and hisses and yowls so abyssally that it sends shivers down your spine.
