The opening narration of the movie Meet the Blacks goes"
Hey, guys. Tonight is the Purge and I want all of my white friends to be safe. Rules of the Purge. You have 12 hours to do any crime you want against anyone you want. You can shoot, kill, stab. Twelve hours of death, mayhem. Lock your doors. Protect yourself. Make sure your rent is paid and all of your pets are put up.
I can't be sure if "put up" here means to provide lodging or to preserve (as in put up jam). Although it seems to mean "protect" or "pen up", I can't find definitions along those lines.
