Step1
First, make sure that there are no staples, random pieces of tape, or other non-cardboard features on your cardboard boxes. If they are taped shut, then pull off the tape, and close all but one side using the "tucking" method.
Step2
Box 1 with digging and chewing contents
Next, gather some of the paper materials for your Digging Box. Place them inside of the box, and then close it.
Step3
Round breakthrough door
Take your exacto knife and cut the door's perimeter only half-deep into the box. Then, make a few cuts into the middle, so that your bunny can have a place to grab on and pull back. I call these "Breakthrough" doors, because they allow your bunny to have fun trying to get it open.
Step4
Make your Rest & Relaxation box by following steps 1 and 3. You can put paper inside, or an old shirt or sweatshirt for your rabbit to sleep on.
Step5
Slotted outer box
Congratulations on making your first 2 bunny boxes! Now, it's time for some reinforcement. Because bunnies love to dig and rip cardboard apart, your box will last longer if you "double box." Cut slots on the top of your outer box.
Step6
Tabbed R&R box
Then, cut tabs out of the ceiling of the R&R room. Additionally, cut a hole so that the bunnies can climb from the 1st floor R&R room to the second floor. Repeat for the Digging Box.
Step7
R&R and Digging Box inside larger Outer Box
After creating the tabs, slots, and holes, assemble your first floor. Put the boxes inside the outer box, pulling the tabs through and making sure the ceiling holes in the boxes line up with the ceiling holes in the outer box.
Step8
Tunnel box w/ willow tunnel
Tunnel Box: If you would like to make a tunnel box, get a willow tunnel (which can be purchased at busybunny.com and stick it inside a long box. Close it up and there you have it.
Step9
Sewing on the carpet
Now, to add the jumping feature, start poking holes in a row along the edges of the ceiling of the tunnel box, and along the sides towards the top.
Step10
Top of carpeted tunnel box
Grab your giant needle, thread it, and start sewing on your carpet by taking the needle from the top, through the carpet, through a ceiling hole, and then diagonally through a side hole. Continue the process until you've got it all done.
Step11
First story
Good job! Now, connect the tunnel box to the Digging Box using the tab and slot method.
Step12
Top of outer box
Continue with the tab and slot method to create a strong bond between the first and second stories. Shown here is a picture of the top of the outer box.
Step13
Complete Bunny Dreamhouse
Put holes into the floor of your upper story box, making sure they line up with the ceiling of the R&R room and the Digging Box. Connect the 2nd story to the 1st story, and there you have it. The Bunny Dreamhouse!
