Elmo needs to know that if he sits on the cat food box She can't get the cat food out of the box.
Martha needs to know that ignoring Floss when she stares at her doesn't make her go away.
Kiffer needs to know that if he puts his head under the cat food packet when we are being fed he will get cat food on his head.
Max needs to know that the fire can get very hot.
Maurice just needs to know that we all love him, even when he is grumpy.
( And you all need to know that scratching my door to wake me up at 5 in the morning does not work in the winter when it is dark and weeing outside the door because you are angry because I have not got up to feed you does not make me very happy!)
