What do I do about the smell of a dwarf hamster cage

I want a dwarf hamster and keeping in my room is almost out of the question. Where do I put it and what do I do about the smell of the cage.

I work at my local animal shelter and take in a lot of foster and rescue animals. I recently took in 14 dwarf hamsters, many of them babies, so I'm dealing with this myself right now.

I'm currently using Carefresh, since that's what I use for my guinea pigs, but it's not quite enough for the hamsters. I'm housing them in two large Crittertrail cages -- one for the boys and one for the girls -- with a lot of add-on tunnels and compartments. While the main parts of the cages don't smell bad, all the hammies like to cram themselves into a single observation tower to sleep in a giant pile, and that enclosed area starts smelling distinctly "mousy" pretty fast. So the hamsters themselves start smelling extremely mousy as well. I have to spend one-on-one time holding each of them every day so that they'll be socialized, and the smell on their fur is driving me crazy. It isn't surprising considering I'm dealing with 14 HAMSTERS! *lol* But I'd be much happier if I can figure out some way to make their sleeping chambers a little fresher and sweeter.

So I've been researching whether I can deal with the odor by using aromatic oils and came across a page with great reviews of a product called Kaytee Soft Sorbent Natural Scented Bedding (http://reviews-cdn.petsmart.com/4830/144... It's blended with real flowers (comes in three scents: rose, mint, and lavender) and is available at Petsmart and some other online retailers.
