I once thought that when cats curled up into a ball to fall asleep, that they were then "stuck" like that for at least a few minutes, which is why they had to stretch when they woke up. I also thought that when a cat was asleep curled up in this way, they looked just like Russian hats. I thought that since my cat was curled in a ball fast asleep, I had just enough time to put her on top of my head and turn her into a Russian hat. My cat put a quick stop to this notion by immediately running down my back with her claws out.
