Not sure how this one slipped through the cracks, but here's a star studded family movie about characters transforming into animals. No word if there's female content, or any process at all (this teaser trailer was more of a proof of concept so there's no telling if the actual transformation will be anything like that). I will say it is likely for the wife and daughter to try the crackers at some point, given that the plot revolves around the three of them and the crackers.
(original teaser, it's actually from 2013)

Could be something, could be nothing... but I think it's at least the most transformation focused plot I've heard in a while.
