If she's keeping it contained in a carrier, I don't think anyone would have any problem with that. She can put the carrier on her lap and reach in to pet it (except during take-off and landing), and we are still happy.
It's roaming the cabin, rubbing up against other pax and spreading it's dander around, and urinating and defecating on the carpeting that people have (IMHO) a legitimate problem with.
