  1. Median and range of the total and partial pain scores determined by blinded observers and ‘gold standard’ based on video analysis recorded at 4 time points during the perioperative period in cats undergoing ovariohysterectomy.
  2. * Pain scores in T2 significantly higher than T1 (p < 0.001).
  3. † Pain scores in T3 and T4 significantly lower than T2 (p < 0.001).
  4. Subscale 1 ‘Pain expression’ - miscellaneous behaviors, reaction to palpation of the surgical wound, reaction to palpation of the abdomen/flank and vocalization.
  5. Subscale 2 ‘Psychomotor change’ - posture, comfort, activity and attitude.
  6. Subscale 3 ‘Physiological variables’ - arterial blood pressure and appetite.
