One of the cats I used to have before she died seems to have done a better job then. One day I was walking to my house from the bus stop because the car had messed up. And I usually had my hair in a pony tail all the time. And snowball (the cat) was used to me having a pony tail and my mom bringing me to the house in the car. When I got to the porch and she saw me and didn't recognize me, she got up on the porch and started walking back and forth at the front of it with her tail fluffed out (that was her way of saying go away or your gonna get scratched) and she wouldn't stop hissing until my mom came out and snowball figured out it was me...
