Control issue.. yes
scare tactic... no

JLOWE, I would encourage you to try and convince your mom by presenting her with the facts and trying to get her to interact with a little bp at a pet store. Maybe print off some of those "cute" baby bp pics have and leave them laying around. As a last resort, name the cutest, most relaxed bp at the pet store after your mom then introduce them.
