Oily fur&stress go together like peanut butter&jelly?

Cat skin has sebaceous glands that secrete sebum, a greasy substance.  When stressed, the glands shift into overdrive.  This makes perfect sense. Many of the calls I receive come from homes in which the owner has either moved recently, just given birth or travels often. These can be high-stress situations for some cats.

Those glands must be pouring out oil when the vacuum cleaner monster invades the living room!
