I know there are survivalists and "doomsday preppers" out there, and others who have experience in this area. I'm not a doomsday prepper myself, but I'm becoming increasingly and rapidly concerned, given the instability of my country (U.S.) and the likelihood of war coming to our actual soil.
Please, no political comments or trolling. I'm not here for that, and this could also pertain to simply surviving through a large-scale natural disaster as well. I just want to know, how long does canned food last on the shelf to be safe to eat? Vegetables, fruit, soup, chili, etc. Is boxed soup less likely to last long? Should they be kept in a cool environment (such as my unheated garage, which doesn't freeze due to the furnace being in it), or is room temperature better, like in my food pantry?
How long does bottled water last, also? I'm thinking like the larger jugs of drinking water. How about canned and dry cat food?
Finally, any estimate on how much food, drinking water, and medical supplies I should store at a time for 1 single adult and 2 adult cats? While some berry foraging in summer could be expected, and there is some availability of game and fish (my family hunts and fishes, though I personally don't), there wouldn't be a lot of "free" resources, and there would be competition for it if a large-scale disaster or rationing were to happen.
