Then this weekend, I decided that I would like to make my own little cardboard house... So I made up a box I had, and cut it in half. (theinspiredroom.net)
And, in a glass case in an antique store were these little vintage cardboard houses.. (theinspiredroom.net)
The boxes can be thrown out with the weekly cage cleaning and a new cardboard house can be used for the next week. (smallanimalchanel.com)
