Oh my God do I love my (cat's) Furminator. Furminating the cat is such a peaceful experience, like one of those little mini-Zen sand gardens.

A word of caution, though: It's basically just a clipper blade attached to a handle, so if you Furminate your cat four times a day because she looooooooooooooves it and it makes her less hairy you will basically shave off all the hair except for the top layer of guard hairs, which can cause a slight skin condition (for the cat) and guilt complex (for the owner) until the undercoat of hair grows back.
