I want The Girls to get themselves ready for bed tonight. If Pickles knows enough to gnaw on her house to get my attention, and food, she can progress to playing, and putting herself back in the cage, go to sleep. So can The Twins.
Funny thing, they actually could do this, I've trained them well enough, but it's the in-between bits that would make this untenable:
Pickles wants The Twins dead, or at least out of commission which requires missing body parts. And they don't always play safe on their own--take huge risks, so their humans have to be there and aware to break falls, and otherwise do security guarding.
Ah, well, it isn't a Full Clean Out tonight; we made sure of that as it's my husband's birthday, so quit play, elementary cleaning, nighty-night.
