Pull the bowls out. That's the problem. And no need to scent the Sippers. They can smell the water. They'll find it.
If you really want something, put a few drops of vanilla extract in the water reservoir. It will encourage them to drink as well as make their urine smell less potent.
Lots of people have asfs and mice in the same colony. They breed, raise their own babies, and do their own things.
