在为期6年的44只家猫训练，以执行一个达到移动光点的运动，在爪使用的偏侧性进行了研究。记录爪偏好和爪性能。在50%的标准下，在组的水平上没有发现显著的爪子偏好。当考虑90%的标准时，23名受试者对一只爪子有明显的偏好。在这些强烈偏侧化的动物中，左爪猫（N =17）多于右爪猫（N = 6）。视觉-运动表现分析包括反应时、运动时和到达准确性。偏侧化的猫比非偏侧化的猫有更快的反应时间。用得多的爪子比用得少的爪子有更短的反应时间，更短的运动时间，也更准确。因此，研究结果表明，被偏侧化的功能优势。此外，研究结果证实了猫的爪子偏好的不对称性的存在，并显示爪子偏好和性能之间的一致关系。
Laterality in paw use was investigated over a period of 6 years in 44 domestic cats trained to perform a reaching movement toward a moving spot of light. Both paw preference and paw performance were recorded. At a 50 percent criterion, no significant paw preference was found at the level of the group. When a 90 percent criterion was considered, 23 subjects had a significant preference for one paw. Among these strongly lateralized animals, there were more left- (N =17) than right-pawed (N = 6) cats. The analysis of visuo-motor performances included reaction time, movement time, and reaching accuracy. Lateralized cats had a faster reaction time than nonlateralized cats. The more-used paw had a shorter reaction time, a shorter movement time, and was also more accurate than the less-used paw. Thus, the findings demonstrate a functional advantage of being lateralized. Moreover, the results confirm the existence of an asymmetry of paw preference in cats and show a consistent relation between paw preference and performance.
