Thanks for those tips, they're good ones.
Remembering food for any animals is easy to overlook- I've done it myself in the past.
One little-remembered source of clean water is your water heater- the water is flat ( shake it in a bottle to re-aerate it ), and may have minerals in the bottom of the tank when you first start draining it
( the hose barb at the base, behind the access panel- be sure to kill the power, just in case, and do not restore it until you get the tank refilled, later )
but it's potable.
Another overlooked source of water is every toilet tank ( not the bowl, mind you! ) which has about 5 gallons in it. If you're paranoid or fastidious, water purification tablets can be used to treat it, but it's perfectly sanitary, despite how it sounds!
Hey Backhoe!
Those cats won't be denied, lol! I know about the water heater and toilet tank as sources of emercency water sources. My biggest worry is if the vehicles are disabled, and there is a forced evacuation. How do you pack it all out? If I was settled permanently, mind you we're in the desert, so no 8 ft of polluted water to worry about(plus we have the wrench to immediately shut off the gas), why should we evacuate if we have ample supplies? Heck, the Mojave river is just down the road, and so is the CA aqueduct.
