Treatment 1 included 2% lidocaine (4.0 mg\/kg); treatment 2 included lidocaine and methadone (4.0 mg\/kg and 0.3 mg\/kg, respectively); and treatment 3 included lidocaine and morphine (4.0 mg\/kg and 0.1 mg\/kg, respectively). All drugs were injected in a total volume of 0.25 ml\/kg via the lumbosacral route in all cats. During the anesthetic and surgical periods, the physiologic variables (respiratory and heart rate, arterial blood pressure and rectal temperature) were measured at intervals of time zero, 10 mins, 20 mins, 30 mins, 60 mins and 120 mins. After cats had recovered from anesthesia, a multidimensional composite pain scale was used to assess postoperative analgesia 2, 4, 8, 12, 18 and 24 h after epidural.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The time to first rescue analgesic was significantly (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      &lt;0.05) prolonged in cats that received both lidocaine and methadone or lidocaine and morphine treatments compared with those that received lidocaine treatment alone.
