I used to leave cleaning out much longer then a bit longer but the smell of amonia quickly becomes over powering.

Yes. The risk of them falling out is what has made me keep them in their stinky tank for so long!

I never usually clean out hamsters this often but these two are just so incredibly smelly that I have resorted to that just because I thought the smell must be too intense for their tiny respiratory systems.
