Each can contains 4 servings of food. Each family member has a chance to get sick if they don't eat this item within 10 days.
Each bottle contains 4 servings of water. Every day you have the option to give any of the members your water. Members of your shelter can go around 5 days without water before death. (Takes up 1 space)
