Finally the panels arrived, and I made Bosse's condo tonight!
Bosse is suuuuper happy with it! He has been exploring and having major binky-fits for the last hour or more! He is just MAD with happiness, I've never seen him binky like this before! And he's still going on as I write this.
I'm going to add another floor, and probably expand it upwards so its 4 cubes tall. And I'm going to replace the cube floors with proper wooden floors, but this is as good as I could make it myself for now.
Over the cube flooring, i have wrapped fleece around two thin wooden plates and it seems to do the trick
Now that his condo is done, I might not let him be 100% free range anymore. But for tonight I will let him roam, so he doesn't think condo + bunny = locked up/prison.
