They are both sulking as I locked them out last night.
I had left the back door open whilst I consumed dinner and watched rubbish TV*, during which time they both traversed the living room several times. As the sun set and the temp dropped a bit I closed and locked the door. Just as I was going to bed one returned and stared at me through the glass. I really really couldn't be bothered to let him in, so they both stayed out all night (one usually does, the other normally likes to be in at night).
