These laws may end up being passed, but there is no way to enforce them. they aren't going to go door to door or anything like that. There may be a damper on feeder mice etc. but that can be overcome by self production.
The prarie dogs were just a reason for them to start throwing this all around. the fact is, if they ban all reptiles, there is a lawsuit regarding discrimination. Dog attacks happen daily and some are fatal. If they ban one pet, they will have to ban them all!
I would seriously file a discrimination suit if any such laws ever get passed in Massachusetts.
