Studies were primarily related to the assessment of pain in relation to surgical procedures , and no clear distinction was made concerning the onset of acute and chronic pain .
The metrics used within the tools appeared to focus primarily on the sensory aspect of pain , with no study clearly discriminating between the sensory and affective components of pain .
Objectives The objectives were to review systematic ally the range of assessment tools used in cats to detect the behavioural expression of pain and the evidence of their quality ; and to examine behavioural metrics ( considering both the sensory and affective domains ) used to assess pain .
Comparison of injectable robenacoxib versus meloxicam for peri-operative use in cats: results of a randomised clinical trial.
The objective of this study was to evaluate the efficacy and tolerability of robenacoxib , a selective cyclooxygenase-2 inhibitor , for the treatment of post-operative pain and inflammation in cats . The study was a prospect i ve , multi-centre , r and omised , blinded , non-inferiority design clinical study to compare robenacoxib to meloxicam .  Ninety-six cats undergoing surgery at eight centres in Japan were allocated r and omly to receive a single s.c . injection of robenacoxib ( 2 mg/kg , n=67 ) or meloxicam ( 0.3 mg/kg , n=29 ) shortly before induction of anaesthesia . Most cats underwent soft tissue surgery ( n=87 ) , mainly  ovariectomy  ( n=68 ) . Post-operative pain and inflammation were assessed at 3 , 8 and 22 h after recovery from anaesthesia using numerical rating scales . For the primary efficacy endpoint ( total clinician score ) , robenacoxib had significantly better efficacy than meloxicam , the relative efficacy ratio being 1.47 ( 95 % confidence interval 1.19 - 1.78 , P=0.0003 ) . For the secondary efficacy endpoints , robenacoxib was superior to meloxicam when assessed on the basis of posture , behaviour , pain on palpation and overall pain control , while meloxicam was superior with respect to wound heat . No cat in either group required rescue analgesia therapy . In tolerability assessment s , pain during injection and pain and inflammation at the injection site 22 h after recovery from anaesthesia were rated significantly less with robenacoxib compared to meloxicam . Both treatments were well tolerated on the basis of clinical observations and blood tests , with no significant differences between groups . In conclusion , single pre-operative administration of robenacoxib was well tolerated and had superior efficacy to meloxicam in reducing post-operative pain in cats
