Well, we found the cubes! We decided to go with a 4x2x2 cube setup instead of 5x2x2. We also decided to have one shelf 12 inches up that is two cubes across, and have the roof just above that part be a grid higher (so she can be on her shelf and still stretch vertically if she wishes). The condo is far from finished, as not all the zipties are tight, none of them are cut, and we also have to cut some zipties off to allow for the door, but I think it should be at least functional by tomorrow, even if the shelf is not ready. We also got this rubbery vinyl flooring stuff at Home Depot which will be put underneath. It’s still pretty textured but is waterproof, so the carpet wouldn’t potentially get soiled.
Here is when we just got started and Noelle kept coming over to investigate:

Here’s what we have so far:

Update: She’s in her pen now. We put her whole cage in the pen so that she could have some time to adjust and still have something familiar to climb back into. The plan is to remove her cage once she adjusts, so she’ll have more room to hop around, and just leave the litterbox. She’s being a little stubborn right now and sulking about it, staying in her small cage and not exploring the pen, but my neighbor said last night she came out to eat the carrots we’d put on the pen floor, and to lounge in her litterbox a little. So it’s progress!
Bunnies! So stubborn! I guess we’ll just have to let her sulk a little till she gets over it and decides to like her pen. =P I think it’s the vinyl flooring she doesn’t like, preferring the newspaper of her cage of the carpet of our floor.
