I put the carrier on the floor, put the FerretVite and bottle into my pocket, then put the ferrets into the carrier. The first order of business is to find them. Usually they're in plain sight, in their cage or under the couch. Everyone I can find goes into the carrier and onto the porch. Think hard, and then plan it out.
Kids love to be involved in planning.
So get it together and design your disaster plan, with an eye toward the safety of your ferrets. Time it and see how you do. Someday it will matter. Or maybe it never will. Murphy's Law on Disaster Preparedness states that if you're ready, it won't happen.
