We learned one year when we faced immediate evacuation (but didn't go, it's a long story) and we were on our last bag of chicken feed, to never get down to one bag of any animal food! We now keep at least two bags of dog food, and two of chicken feed on hand at all times! Because of our location and constant fires, we get "stuck" at home and cannot get to town to buy feed. Now we are ready for a couple weeks at least without leaving. Likewise our freezer is stocked with people food as well!
