Thanks! Yes, I made the hay rack after I had thought about it for a very long time. It was difficult to find a proper way to serve the hay, especially since the bunnies love to just pull it and spread it around.
The setup is really so great. No mess on the floor. No extra space taken from the room. The area is huge for the bunnies, I mean they can, well, not really run like they do long distance, but they chase each other sometimes. Only Malla can make the jump from the lowest level to the second level without jumping on the hidey house, for Nelli it’s too high, but even Malla does it only if she gets scared, otherwise she’ll prefer using the “step”. (Of course they are not kept in the cage all the time, but when they are locked in I don’t feel as guilty as the space is big.) The only downside with this setup is that if the bunnies decide to make lots of noise during the night, my daughter can’t escape it, lol
Luckily she doesn’t wake up often, even though I do sometimes (and our bedroom is down the hall, haha).
