Assessment of the cutaneous trunci muscle reflex in healthy cats: comparison of results acquired by clinicians and cat owners.

objectivesThe study aimed to evaluate the cutaneous trunci muscle reflex (CTMR) in healthy cats using methods performed by the clinician and the cat's owner at home.

methodsA total of 55 healthy cats without neurological abnormalities were included in this study. CTMR evaluation was performed sequentially in each cat using three methods by a clinician: method A, pinch skin with a straight 14 cm Crile haemostat forceps; method B, displace fur with the tip of a pen or haemostat forceps; and method C, poke skin with the tip of a straightened paper clip. The normal response rates for each method were obtained and compared. A 'CTMR performance score' was assigned for each cat, reflecting the presence of a normal CTMR response using one or more of the three methods. An 'owner performance score' was also obtained, reflecting the response of the CTMR when performed at home by the cat owner. The two scores were compared as paired data for each cat.

resultsThe CTMR was elicited normally in 17 (31%), 27 (49%) and 16 (29%) cats using methods A, B and C, respectively. Method B delivered a significantly higher percentage of normal responses. When comparing the 'CTMR performance score' and 'owner performance score', the percentage of normal responses was 60% and 100%, respectively, which was significantly different. CONCLUSIONS AND RELEVANCE: The overall normal response rate of the CTMR in healthy feline subjects was low when performed by a clinician, regardless of the method applied. Conversely, a high percentage of normal responses was obtained by cat owners performing CTMR at home, potentially indicating the impact of stress on the CTMR performance.
