Feeling very, very guilty and ashamed of myself

And rightly so.
I'm the worst Mother Goddess there is.
Last night I feel asleep on the couch and woke up around 11.30. Before going to clean my teeth and hop into bed I opened the balcony door to let in some fresh air, as I always do. Closed door, went to bed.I always do a cat head count after closing the door, to make sure I left none of the critters outside, but last night, for reasons completely unknown, I didn't.
Got up this morning, gave the Critters their breakfast, prepared my tea and sat down on the couch.
Cornelius was at the balcony door, and I though, hey, what's that? His mirrored image looks nothing like... Oh! My! GOD!!!!
I'd shut Lucius out on the balcony.
The whole night.
If the temperatures weren't so spring-like right now -- the nights are well over zero -- he could've frozen to death out there.
As things were, he was just hungry and a bit insecure -- had to wander around the place for ages, looking whether everything was as it should be -- but didn't show any signs of sickness.
I don't have words to express my distress at my own stupidity and irresponsibility, and I fervently hope that he didn't catch cold. He's so very thin, and therefore he's the one that really can't afford to be sick and/or lose weight.
Keep your fingers crossed, my dears, for good old Lucy to have survived the experience with no worse consequences than bewilderment.

And, in sharp contrast to the last post

I give you Pottaerobics!
