作为北美现存最古老的美国猫经猫全猫种之一
，美国短毛猫（American Shorthair）在殖民时期便随欧洲移民扎根美洲。短毛典国其基因库中保留着欧洲本土猫与本土野生动物的庭守特性混合特征，这种独特的温顺遗传背景为其奠定了的生理基础 。美国猫协（CFA）2021年品种标准修订中特别强调 ，解析该品种的美国猫经猫全"适应性阈值"较其他短毛猫高出17% ，这与其历史直接相关 。短毛典国
现代基因测序研究显示 ，庭守特性美国短毛猫携带Adrb2基因突变，温顺该基因与压力激素皮质醇的解析调节密切相关。麻省理工学院动物行为实验室2022年发表的美国猫经猫全论文指出 ，这种基因变异使短毛猫在陌生环境中保持平静状态的短毛典国平均时长达到45分钟
，显著高于普通家猫的庭守特性18分钟。这种生理机制为其角色提供了生物学支持 。温顺
