为系统梳理猫狗差异及其对消费行为的影响并建构整合性框架，以Web of Science及中国知网1990~2025年间收录的704篇文献为数据源，采用文献述评方法，从生理特征、行为特征、个性特征和文化象征维度，阐释猫狗的物种差异，进而借助心理距离、心理所有权理论及依恋理论，剖析猫狗差异影响不同消费行为的理论机制；在此基础上，归纳猫狗差异对猫狗消费、人类个体消费及亲社会消费的影响，提炼出宠物个体特征、消费者个体特征、文化背景的调节作用。针对现有缺口，提出未来研究可围绕数字技术赋能、符号价值建构、人口结构变迁及本土文化情境等方向深入拓展。

To systematically examine the species differences between feline and canine and their implications for consumer behavior, this study constructs an integrative framework based on 704 articles indexed in Web of Science and CNKI from 1990 to 2025. Employing a literature review method, this study elaborates on the species differences between feline and canine across four dimensions, namely physiological traits, behavioral characteristics, personality attributes, and cultural symbolism. Furthermore, drawing upon psychological distance theory, psychological ownership theory, and attachment theory, this study analyzes the theoretical mechanisms through which feline- canine differences shape different types of consumer behavior. On this basis, this study synthesizes the effects of feline-canine differences on pet-related consumption, individual human consumption, and prosocial consumption, while also identifying the moderating roles of pet-specific characteristics, individual consumer attributes, and cultural contexts. By identifying gaps in the existing literature, this study proposes promising future research directions, including digital technology empowerment, symbolic value construction, demographic structural changes, and local cultural contexts.
