Abstract

Carbon dioxide (CO2) thermal lasers have previously been validated for the assessment of nociception in cats. This experiment sought to assess the potential impact of factors associated with age, sex, body weight and sterilisation upon nociceptive threshold as measured by latency to display a behavioural response. Cats (N=113) were exposed to a CO2 thermal laser three times during a 45–60min test period depending upon the interval between tests. A minimum of 15min elapsed between consecutive tests on any one individual. Time to display either a skin twitch or withdrawal was measured. Intra-class correlations showed the three measurements to be repeatable across tests for any given cat (ICC=0.482; P
