Margaret Woodhouse: Know Your Cat's Purr Points [2000] hardback

Although not "serious", but based on a real acupuncture guide book, this illustrated guide to the ways in which cats respond to being stroked, tickled and squeezed in the right places, should bring smiles of recognition to anyone who enjoys coaxing a purr out of their cat. Sections include details on: the pleasuring of the back; ear points, "keep fist open and fluid for a ripple action. The subject will vibrate from the ear outwards"; tummy points, "Subjects will generally be transported into some unrecognisable alter-ego". Each move is illustrated in stages, with hints on technique, plus a "Purrometer" rating.
