Pouncing Jeans

A pair of MrsCyclops' black jeans is sitting across the top of a cupboard on our landing.  When I went up to bed last night in the dark, I nearly jumped out of my skin when they reached out at grabbed me as I passed.  

Turns out there was a cat (Moon) blending into them.  Obvious with the light on and her head up.  Not so obvious in the dark when she was stretched out on them pretending to be a shadow.
