If the disaster forces you to stay home and be self sufficient, you'll need to have emergency stores of pet food and supplies. The Absolute Necessity Stocking water reserves and learning how to purify contaminated water should be among your top priorities in preparing for an emergency. You should store at least a two-week supply of water for each member of your family, including pets. Everyone's needs differ, depending upon age, physical condition, activity, diet, and climate. A normally active person should drink at least two quarts of water per day.
Hot environments can double that amount.
You need additional water for food preparation and hygiene. Store at least one gallon per person, per day and one to two quarts per animal, depending on size and type. Minimize the amount of water your pets need by reducing their activity and keeping them cool. How to Store Emergency Water Supplies You can store water in thoroughly washed plastic, glass, fiberglass, or enamel-lined metal containers. Never use a container that has held toxic substances, because tiny amounts may remain in the container's pores.
