I have 4 reptiles in our bedroom, no smell whatsoever except for my Yankee candle We also have 2 snakes in QT in the living room and a T., also no smell. Now, if you walk into our rodent room, there's definitely a smell, but it's a barn type smell, and I think barns have the best smell in the world. Right up there with Christmas trees and fabric softener lol. But I'm weird like that.

If you're breeding rodents, then it's understandable that she's smelling something. You can NOT get rid of that smell unless you have a sealed room and an air filtration system.

You might want to have a chat with her, see if it's the reptiles themselves she has an issue with rather than their 'odor'. Maybe you can even get her to handle them, or at least get accustomed to their presence.
