What should I consider when storing water for pets?

April 5, 2026

Quick Answer

When storing water for pets, consider their individual needs, the storage container's material and size, and the water's quality and expiration date to ensure your pet's health and safety.

Choosing the Right Storage Container

When selecting a storage container for your pet’s water, prioritize a food-grade material such as stainless steel, BPA-free plastic, or glass. Avoid using containers made from aluminum, copper, or other metals that may leach into the water. Consider a container with a capacity of at least 1 gallon (3.8 L) per pet to provide a 3-5 day supply in case of an emergency.

Water Quality and Expiration Date

Regularly check the stored water’s appearance, smell, and taste to ensure it remains safe for your pet to drink. Check the water every 6-12 months and replace it if it has an off smell, slimy texture, or unusual color. Store the water in a shaded area to prevent algae growth, and keep the container away from direct sunlight, pets, and children to prevent contamination.

Calculating the Right Amount of Water

Determine the right amount of water to store based on your pet’s species, size, and activity level. As a general rule, store 1 gallon (3.8 L) of water per 10 pounds (4.5 kg) of body weight per day. For example, a 20-pound (9 kg) cat would require 2 gallons (7.6 L) of water per day, so store at least 6 gallons (22.7 L) for a 3-day supply.
