Like the human...if you treat them kindly, they will know...
Again cats are not savage avain influenza transmittor...they might only get infected by enclosed high titer virus enivornment and even more difficult to transmit those virus to human
Washing the hands will be a good preventive measure..

貓同人一樣, 你對他好, 他們會知道...街貓不是洪水猛獸, 貓除了被人用黑太陽731毒氣實驗室式高病毒濃度(titer)實驗中中到H5N1外,很難傳流感到人, 摸完洗手就ok啦...
