Sure, she nearly squat them in her zealousness to care for them in the beginning. But Pearl has since proven herself to be a big help to Minnie and her babies.
She's right there ready to step in as protector any time Minnie needs her. I pity the poor fool who tries messing with these kids.
It's nice for a new Mom to get the chance to relax for a leisurely bath knowing her babies are safe.
I personally would prefer bubbles to dust, but to each her own.
