I don't store much but I've got loads of flour for making bread (bannock, scones, biscuits) and a sack of rice. Porridge oats could make oat milk and the tins of green lentils and chickpeas would do lots of curries - oh, and some veg in the garden. Cooking could be a major problem with no power supply, though! I'd have a problem with pet food (vegan goes hunting/trapping?) and could I manage at all without all the tea and coffee?
What has survived in your garden with minimal or no watering?
What sort of family would you not want to marry into?


Luckily, the cats would be OK for quite a while.
