Looking for a hidey house and some wood!

[Mookie]

Hello! It is time for me to switch out the old wood in my chins cage and replace it with some fresh new wood! I have been looking around, but can't seem to find what I am looking for. I am looking for a hidey house that is two levels, and not very long, just tall. I am looking for a similar height and width to this toy http://simplychintastic.com/images/playtime/Tower.JPG... however, these are currently not available. Please let me know Also I am looking to purchase some apple twigs for my girl as well. Thank you!
