Kitties During the Night

All winter: no screens on the windows.
Sleeping with the bedroom door shut, and kitties on the outside.
During the night, we slept.
Novel concept.

Warm weather; screens in; windows open.
Kitty-claws ripping the screen to wake us. 
"Let me in, let me in, I want a couple of bites of kibble!"
Kitty gets the idea that she can have whatever she wants during those nocturnal hours.  She knows the threat-of-her-claws is power.
"Let me use my claws to snag the carpeting.  You'll get up to stop me.  I know you will.  Then I'll get kibble.  Or water.  Or you'll operate the all-night rotating doors."

I do not care to be woken at 4:00 a.m.
Kitty may have to be spending the rest of her nights on earth locked in the garage.

Well, I've been up for over two hours now.
At least I made a lot of headway on preparing Maggie's high school transcript in these early hours before sunrise.
