I'm about to make changes to my house and I can't put away everything. How long can stuff sit in the crate before I take it out? Will it go poof after a few hours as if it is not locked down? It might take me a few tries to get my house the way I want it to be but do not want to have to unload the crate after every attempt. But then I don't want to lose my stuff either. Thanks in advance for your advise.
