EVALUATION of blood pressure is indicated in a large number of situations, and facilities for its measurement are now essential in all practices seeing cats. This article describes the different techniques and machines currently available for non-invasive measurement of blood pressure in feline patients. It also provides some guidelines on interpretation of readings. As clinicians will be all too aware, blood pressure is a labile parameter — and not just in cats.
