If you don't know this fairy tale, you can read about the Princess and the Pea here.
One of the katz apparently thinks she is a princess:
Every night, mom piles these pillows on top of her alarm clock so Millie doesn't step on it and turn it off.
In this picture, it looks like I'm balancing her on my head:
I don't know why she gets all those pillows. Do I get any pillows?
Ooo... Now's my chance! What do you think? Should I try out all those pillows?
