This is Smudge and she likes:
Trying to trip up her owner in the morning by rolling on to her back right in front of her when she is walking.
Trying to trip up her owner by running in front of her in the morning when it's breakfast time.
Banging into windows by hurling herself at them when it's time for crazy cat hour.
Chasing shadows under the bed.
Tiny toy mice that her owner is supposed to throw about the room for her for at least a half hour. No matter what her owner might be doing at the time.
Children (time to hide in the cupboard!)
