Wow! Tortellini is the perfect word for describing this classic kitty pose. Filou has obviously perfected this pose to an Art Form. One of my cats "Cecil" has his own sleeping pose. He prefers to sleep on his back with his front legs streched out forward, and his back legs spread out! He looks slightly obsene sprawled out like this, but he looks so funny and relaxed that it always brings a smile to my face.
