The dirt isn’t such a great idea for indoors. But a shredder is a diggy box maker’s best friend. First, know that soy based ink is safe for bunnies, so you are in great shape with a yellow pages or other phone books. They are good toys by themselves, because a bunny will open it and start ripping out pages. Good fun. So toss last year’s down on the floor and watch her enjoy it.
You can take one and shred up the pages to fill the diggy box. Also, put a cardboard box on it’s side, fill it with shredded paper, and let her tunnel into it. BB has a video of one she gave to Vivian or Bailey, who burrowed into it, pushed it behind her, and was a very happy disappearing bunny.
Toilet paper rolls stuffed with hay is a good toss treat. It is chewing, tossing, and digging out goodies all at the same time.
You can hide a treat or two in the middle of a diggy box so she has to find it. Keeps her motivated to stay digging longer.
