A new study shows that sociable prairie dogs like nothing more than a good kiss and a cuddle, particularly when they have an audience, the Daily Mail reports.

Adam Eltorai from Washington University led the study, which found that the larger the crowd watching them, the more adult prairie dogs kissed.

Prairie dogs have a similar style of greeting as many humans, touching their lips together and even sometimes making contact with their tongues. The kissing is often accompanied by grooming or cuddling. （点击《每日邮报》查看原文）

土拨鼠享受接吻被围观

       最新研究发现，擅长交际的土拨鼠最喜欢接吻和拥抱，尤其是在有人围观的时候。

       英国《每日邮报》消息称，在华盛顿大学亚当•奥特莱的带领下，科学家们对密苏里圣路易斯动物园的25只黑尾土拨鼠进行了研究，结果发现，土拨鼠和人类一样喜欢被关注。成年土拨鼠接吻时，围观的人越多，它们就会更加爱意绵绵，亲吻得更多。

       土拨鼠的问候方式和人类差不多，它们用嘴唇碰触对方，有时还用舌头相互接触。它们接吻时往往伴有抚摸和拥抱的动作。
