This is Yoghurt. She thinks she’s a human. And likes to do human things like be a bed hog and recently, snuggling under the covers.
And when you wake her by readjusting the covers, she moves to what she thinks is her rightful place – top of the bed, head on the boy’s pillow – and goes right to sleep, perfectly camouflaged by the sheets. Sometimes, she even snores or makes dream noises. One day, I’ll get that on video for you.
