That’s too bad for them. But they will get more furniture someday, I’m sure of it. ^^ Did you consider building something yourself? (given the possibility) I’m planning to do this, as soon as I got the time for it. I find the prices for some cheap boards put together quite high. It shouldn’t be too hard, I think.
Outs love the occasional cardboard. :D I’m sure your bunnies are living their best life nonetheless.
