The other major drawback
The other major drawback is that the wood frame is difficult to clean effectively, so that if your bunny hits it with urine it will be very difficult to remove the odor.
With the bottom latched up the floor is very solid, but I am not sure this is enough to prevent irritation to Specky’s feet. As an added measure of comfort we have a solid piece of wood inside the rabbit cage as a solid surface to sit on, along with a litter box (which so far Specky has been using very well!). We are going to build him a nestbox out of wood, but we’re not in a hurry because he loves his cardboard box! A photo of the cage can be found in the upper right corner of this article.
