One thing I wonder about - since it was applied topically, was there any way to control for mice grooming themselves (licking themselves)?

There is, they would have to apply the chemical somewhere like the back of the neck, then house the mice in single cages.

What I would guess they really miss here is the long term chronic exposure on a mouse vs. most of it being washed away in a typical shampoo usage. How long does it take the chemicals in question to penetrate the skin? How long will the vital cells be exposed in either case? Did the article say anything about what kind of cancer, was it localized to the exposure site?
