With all the snow in North America and parts of Scandinavia, and the tsunamis in Asia, I'm wondering how much cat (or dog, etc,) food you usually consider your "iron ration". We rarely have natural catastrophes other than flooding or the occasional small earthquake in this area, but having grown up in a region where blizzards and hurricanes weren't unusual, I always try to have enough cat food to last several weeks on hand. 9/11 also made me a bit paranoid about not being able to get the food Jamie likes. At the moment, I have about 200 1-meal cans of cat food, and roughly 9 lbs. of dry food stored away. That was bought for two cats, one almost 14 lbs., and the other a dainty 6 lbs.. I realize that's "overkill", but I buy in bulk online, and not just for us. Do you buy pet food as it runs out, or do you think ahead and make allowances for strikes, rotten weather, terrorist attacks, illness, etc.?
