Typically I wouldn’t have to clean the burrows, they should do that on their own. Rabbits don’t normally make a mess in their sleeping quarters if given an opportunity not to. I gave them dirt not straw or hay. I can clean the tube yes, we’ll see what it’s like. They don’t soil their tube in the house so I don’t know what they’ll do with this.Are you and to clean inside the burrow? And the tube?
