Yes! I have noted that young bucks smell like freshly popped popcorn. Older bucks don't smell nearly as nice. Does have a mousey odor as well, but I find it can be minimized by not having a lot of plastic junk in the cage. Not that that stops me from giving them lots of toys and stuff; I've gotten used to the smell. There are distinctive smells to different types of populations of meeces; tanks with nursing young have the distinctive baby poop smell, and if you smell that smell without having any babies, it probably means you have a sick mousie.
I have several mesh bags full of zeolite that absorb ammonia and that helps somewhat. It's made for kennels and catteries, and can be recharged every few weeks by leaving it in the sun for a day. Mousie odor does tend to hang on in clothing, hair, and paper items, something I'm embarrassed to say I didn't notice until I took a trip out of town. Everything in my suitcase had a weird odor, and I couldn't figure out what it was. Now I keep items use in the mousery away from things I might use outside the house.
