Cocoa is about 6 years old. We’ve had her for 5 years. I got an x-pen for her pretty much right away after seeing her crammed in one of the “bunny cages” from the pet store. After checking out other pics here, I wanted to add a NIC area, but DH did not like the idea and came up with a simpler idea that I think will work better for her.

The new shelf is 48×18 inches (x-pen is 48×48). I used carpet stair treads for the top. They are stain resistant and cushioned. I put a few banana chips on top to intice her to jump up. This morning they were gone and she was laid out on top. So… I think she approves! The rug below is new too. It’s an all cotton rug from Big Lots.
I also found this for a new hay rack at Big Lots. It’s a wire storage basket turned on it’s side.

Please pardon her rear-end, she’s shedding like crazy! She does have more toys/chews, but I had taken them out when I cleaned/installed the shelf and hadn’t put them back in yet.
