？？回复原因和解决办法

1。trying to get our attention
2。trying to play with us

每当他咬的时候，不要惩罚，如果重了恐怕他承受不了，如果轻了，他以为你在逗他玩儿，walk away是最好的办法
When your cat starts nibbling on you while you are cuddling or resting with your cat on your lap, stand up immediately and walk away. Ignore the cat completely for a short while. You are giving her a message, saying “I am walking away from this behavior.” You can also redirect her energy or activity to toys when she does nibble. Have a stuffed mouse or animal handy. When she grabs your hand and starts nibbling, bring her a toy and allow her to engage that activity with the toy, not you.
