How long would you last?

LS Not so on some points.

Cardboard and paper will end up as toilet paper and fire lighters, plastic bottles for growing seedlings in, tins for making garden alarms, clingfilm, plastic bags will be reused until they disintegrate. In a country not far from you old cans are recycled to make irrigation systems in rural village veg patches.

Late arrivals at you place could possibly be quarantined for a week in an outhouse or tent or shed if they are family

Cats as much as I hate them = Vermin control which will be essential, you can make and or buy doofahs that fit a door or window that the cats can only access the house through, and to enter they have to pass through a short catflap covered tube or box that makes them walk across a bit of constantly wetted carpet that is a mix of water and disinfectant. They will either use that or stay out doors
