Zoom Zoom sleeps like this most every night. When she wakes up, she has a look like "do I HAVE to get up NOW?!? Can't I sleep just a little longer?"
Speedy gets up so quickly (at least she did until the last week or two) that I haven't gotten sleeping pics, except of a few where she tries to sleep late in the afternoon on her purple puff dragon
Here's the both sleeping on my chest one afternoon
Enjoy!
