Homemade Rat House

Marbles and Bandit shredded their last fleece cube so I thought I would give them something different to play with for a while. So I took a small cardboard box, cut off the top and cut two holes in two sides the put it in their cage. Bandit was scared of it at first, but he quickly started sleeping in it and now I find them in it all the time. 

Of course while I was trying to take a picture of it, Bandit came over to see what I was doing.
