This is our solution. Wire crates. $14 from Fred Meyer here in Seattle. Pardon the mess. You'll see the box in the upper right.

Started with one set. Currently own 4. Even have them going around bed.
Use nylon lockties to be able to block areas temporarily. Like sorting laundry on floor. We connect 2 with the connectors and locktie panels on the end. We'll fold them and take them with us when we visit other homes.
Let 2 sections overlap in the middle where they don't equal the size of the wall. That way they can still be moved around as needed.
Cavy owners get VERY creative with these! I even have a play area outside our patio door with the panels on the top like a large crate.
May have to connect them 2 panels high if she'll jump/climb over.
I'm so sorry you're having this problem!
Good luck and let us know how it goes!
