The objective was to evaluate the use of propofol as an anesthetic drug for electroejaculation in the domestic cat. Cortisol concentrations, heart rates and respiratory rates of 20 male domestic cats were examined. The animals were randomly allocated into three groups. Group A (n = 8), were anesthetized with propofol (10 mg/kg) and underwent electroejaculation. Group B (n = 6), were pre-medicated with buprenorphine (0.01 mg/kg), anesthetized with propofol (5 mg/kg) and underwent electroejaculation. Group C (n = 6), the cats were anesthetized with propofol (10 mg/kg) without electroejaculation (control group). Blood samples were collected at four time points (30 min before propofol administration, immediately after the surgical plane of anesthesia was induced, immediately post-electroejaculation, and at the onset of anesthetic recovery). In the control group, the sampling time coincident with the end of electroejaculation was assigned as 21 min after the induction of anesthesia. The mean (±S.E.M.) duration time for electroejaculation was 18 ± 3 min. The duration of anesthesia did not differ (P > 0.05) among the three groups of cats (26 ± 2 min). Most of the cats (17/20) recovered smoothly. Pre-anesthetic medication with buprenorphine did not reduce the requirement of propofol for anesthesia. The cortisol concentrations, heart rates and respiratory rates of the three groups of cats did not differ (P > 0.05). A marked decline in cortisol levels was observed immediately post-electroejaculation. Propofol was a useful anesthetic for electroejaculation in felids with rapid onset, optimal duration of anesthesia for performing electroejaculation, and smooth recovery.
