Hey Blue Moon! If you use toilet paper that is rolled on the cardboard tubes, you can use those. Whenever a roll is finished, I throw it in a box and take some out every so often for Wick. Depending on your bun’s playfulness, you can take a couple and arrange them like bowling pins so they can knock it down, or you can cut them to be different heights, then throw a treat in one and let your buns find it. You can also stuff them with hay so your rabbits need to interact with them and roll them around to get some hay.
Wick doesn’t really play with anything unless I force him to run around with me, but there is one thing he’ll consistently interact with. He has a cardboard ring, which I think came as a part of packaging for a large electronic appliance. It’s very hard cardboard and it’s diameter is big enough that he can hop through it. He does not like it to be standing up (the position where he can walk through it). If he sees it propped up, he goes up to it and chucks it so it’s laying down flat. No idea why he does this, but that’s the extent of him playing.
