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 .
A preliminary investigation comparing pre-operative morphine and buprenorphine for postoperative analgesia and sedation in cats.
OBJECTIVE To compare the postoperative analgesic and sedative properties of buprenorphine and morphine in cats . STUDY DESIGN Prospect i ve , r and omized , blinded study . ANIMALS Thirty-two domestic cats undergoing surgery . METHODS Cats received pre-anaesthetic medication with acepromazine ( 0.05 mg kg-1 ) given intramuscularly and were r and omly allocated to group M and given morphine ( 0.1 mg kg-1 ) intramuscularly ( IM ) or to group B and given buprenorphine ( 0.01 mg kg-1 ) IM . Anaesthesia was induced with propofol and maintained with halothane in oxygen and nitrous oxide .  Pain and sedation scores using visual analogue scales , and heart and respiratory rates , were measured immediately before , and 30 , 60 , 120 , 180 , 300 and 420 minutes after anaesthesia . RESULTS Pain scores were significantly lower at 60 , 120 and 180 minutes after anaesthesia in group B. Group B also had higher heart rates at 30 minutes . There were no other statistically significant differences between the groups . CLINICAL RELEVANCE Buprenorphine ( 0.01 mg kg-1 ) appeared to provide better postoperative analgesia than morphine ( 0.1 mg kg-1 ) and may also have a longer duration of action
