Because dogs and cats are the two most common companion animals, and because both species walk on all fours and are covered with fur (most of them, anyway), there's a tendency among humans to think they are more similar than they really are, which, drew from follows, is completely not the case.

狗和猫都是最常见的人类伙伴，它们都四脚行走，浑身披满长毛（好吧，它们中的大多数），正因为此，人们往往认为它们的相似之处一定超过人类所知，然而完全不是这样！
