This hide is quite large and very spacious inside. It is prefect of you have a clear front enclosure and would like a chance to see your hamster under bedding. 
We recommend adding some sphagnum moss or tissue/paper bedding for the bottom part of the fence. You can secure it better with non toxic PVA glue or Elmers glue. We also recommend adding some bedding in the hide before use.
