This is what I very often wake up to.
They're laying where one's legs generally lay. I don't know how they do it, bc I never feel them piling up in the middle of the night, but by morning I usually have at least one, sometimes two and often three cats squeezing out my lower half. It's not very conducive to rising and shining, but that's not my thing anyway. Rest assured that I am not complaining; I like waking up with these cuties.
