We bought a kennel, put it together, set it next to the bedroom window and then used bolt cutters to make a hole next to the window.
A sliding screen inside allows us to close off her access when we are not home.
It took her a day to even try to go out there. She was in and out several times, always coming back in and making sure we were still here.
She is ignoring it today, or hasn’t noticed that I opened the screen back up this morning.
