I saw a post someone put on FB about making a scratching box out of any sized box.
You cut the end off of it (so that you have the equivalent to a shoebox lid), and then cut the rest of the box into strips. Then you take those strips and line them up in the “lid” that you created, filling it like that until you have something that looks similar to a cardboard scratcher for cats. Then you take dried herbs that the bunny likes (dandelion, chamomile, clover, rose-hips, etc) and sprinkle it in the cardboard like catnip to get the bunnys interest.
I can’t recall who posted it, but it looked like it would make for some quick fun for the bunny that likes to dig.
I use oatmeal tubes and remove the lid and plastic rim/ring; then cut a hole in the side big enough for the bunny to stick his/her head in. Then I poke 4 holes in the back of the tube and attach it to the side of the cage with 2 zip ties, tube open side up and the new hole facing out toward the bunny. This makes for a great hay-rack that’s easy to fill and can hang over the litterbox without taking up too much room. Not sure if that would help or not, but it’s an oatmeal container thing! Good luck on your video!
