I'm grasping at ideas here for you. But is there anyone that lives near you that you could trust to come over mid-day and let Digi out (of her kennel) to potty and play with her for a bit?

Also, I'm not clear on one thing. You say you lock her in the living room. Is the living room connected to the kitchen? Because your problem was her getting into the kitchen garbage or anything off the kitchen floor. If yes, is there a way to block the kitchen off from the living room? Baby gates or something.

I hope you can find a way to keep her safe and happy. I know how upsetting it can be when you worry about them.
