I was in the same boat not to long ago one winter. Bad snow ripped threw and we ended up with no power for a solid week. With well water we ended up purchasing water by the 3 gallon packs constantly. The average toilet takes about 3 gallons to flush 2-2.5 gallons if your lucky. We were pretty much dead in the water for the first 3 days (Including the day of the storm) since our landlord didnt plow the driveway till then. We had no means for a generator either. My Cat who 150% hates being covered by anything such as a blanket ended up letting me piled um onto him like a cat nest and stayed in there all day pretty much for the week.
