Dear William,

　　一般用he或she来表示，比如说“这只小猫是我最好的朋友”可以说成“She is my best friend in my life”，而不是“It is my best friend in my life”。在提问的时候比如说“是公的还是母的？”可以说成“Is it a he or she?”。这句话非常管用，可以试试对任何一个溜狗或溜猫的老外说，他一定会对你刮目相看的！

　　Dear Ms. ABC,

　　I have a question. When we talk about animals in English such as cat and dog，which personal pronoun we could use? We use ' it' or 'she/he' according to their gender?

　　Thanks & regards

　　William
