家里有猫的朋友们，大家仔细观察过猫的耳朵尖尖吗？有些猫耳朵尖尖上长了一撮长长的毛毛，有些猫却几乎没有，还有的猫耳廓里面的毛很长，这是怎么回事呢？猫耳朵上的聪明毛和犟种毛其实猫耳朵尖尖上长的是聪明毛，耳廓里面的是犟种毛。
因为猫在实验室环境中和在家中的行为方式差异很大，所以在实验室中观察猫可能会得出不准确的结果。“The Bengal was the most active breed， while the Persian and Exotic were the most passive. The breeds exhibiting the most excessive grooming were the Siamese and Balinese， while the Turkish Van breed scored considerably higher in aggression towards humans and lower in sociability towards cats.”
