I was about to toss (recycle) the empty half-gallon milk carton. The cat was dancing around my feet asking for breakfast in that feline-way.
It occurred to me in a disaster like an earthquake, I don't want to be giving the cat my stash of bottled water. I might need that. Also, for the purposes of washing, the bottled water would be better used for drinking.
Even so, what if I run out of bottled water. What then?
So the questions are...
If I clean the milk jugs and fill with water from the tap, how long would that be good?
How regularily should I replace the water, just in case I'm forced to drink it?
Are there any health concerns? Would I need to boil it?
