I'm looking into redoing my pen (stacked x-pens instead of just one pen) and I need more panels. Right now, I'm using the wall but I need to be able to open the pens to let the bunnies out. I have to pick the bunnies up to switch them out of the pen and doing that twice a day is hurting our bond. I'd like for them to have their own pens. The pens I'm using are these ones (I have 2 but I'm using the second as a lid to the pen). If it's needed, I could find a way to take a pen apart, but I don't want to do that unless I have to. I'm looking to redo the pen asap. The panels don't even have to be the same brand/style as the ones I have. Thank you!
