Goodbye Odor, it's a water additive used for ferret odor (Petco carries it as does Amazon), you add it to their water and it really works great! I tried it on my male mouse and it seems to work really good (after a week or so). My vet said it should be fine for male rats also.
I personally would not use Fabreeze around any of my critters (or humans)...just a personal choice, no real reason. I also keep Lysol far far away from my critters, I made the fatal error of spraying Lysol in my rabbit Hannah's litterbox one time....she was dead the next day! :0(
