Hey,
I’ll tell you what my bunnies enjoy
mine are only 10 weeks old, so they might still be a litlle more adventurous as yours but they went absolutely crazy about it.
I made them a litlle willow hut myself. I left some of the leaves on the branches and it immediately drew their attention. they loved to climb on top of the hut, just sit inside of the hut and they loved chewing on it so much that it got completely destroyed in 1 week time.
So I made them a new willow toy, this time it’s a tunnel, they love it. they can run through, just relax a bit inside of it and climb on top, offc. because it’s a tunnel so it rolls away a litlle when they jump on top of it so that gives them some extra fun trying to stay on top, or just messing with the other one when she is sitting there. They have had this tunnel for about 4 days now and they already chewed a hole in the side big enough for them to squeeze trough.
Even more fun: I like shoving some of their favorit foods in between the branches so they can search for it and need to make some effort to get it.
All I used for these toys are some weeping willow branches, some creativity and quite some patience. I figured it out for myself how to make it, but I’m pretty sure you can find something on the internet aswell.
It’s quite a lot of work and my bunnies really destroy them so fast. but watching them play with it makes it all worth the effort
If you’d like I can explain you how I made mine.
