Amityville, there is a lot of useful information in your post. Thank you. I appreciate it. However, there is a "only one way is the right way" thinking that is evident here in posts sometimes.

Both hamsters have been examined by a veterinarian and they are very healthy with space and substrate that exceed the recommended requirements. The Roborovski's home reeks after a week. Not the Syrian's. The veterinarian said some hamsters just have a stronger odor than others. Hopefully, Ria and Griel won't have that with their hamsters.
