How to Store Wet Pet Food? Dog & Cat Food Storage Guide

Wet food is a favorite among many dogs and cats thanks to its rich aroma, soft texture, and high moisture content. Whether you feed canned food as a complete meal, mix it with kibble, or offer it as an occasional treat, proper storage is essential for keeping your pet's food fresh and safe. But how long can wet pet food sit out? Does canned food need to be refrigerated after opening? And how should unopened cans be stored?

How Should You Store Unopened Wet Pet Food?

Unopened canned pet food is designed to remain shelf-stable until its expiration or best-before date when stored properly. Keep unopened cans in a cool, dry place away from direct sunlight and excessive heat. A pantry, cupboard, or temperature-controlled storage area is usually suitable.

Avoid storing pet food next to ovens, heaters, or other places that experience large temperature changes. High temperatures can affect food quality and may shorten its shelf life. Before feeding, always check the expiration or best-before date printed on the package. It's also a good idea to follow the first in, first out rule: use older cans before newly purchased ones so products don't sit forgotten at the back of the cupboard.

Check the Can Before Opening

Before opening a can of wet food, take a few seconds to inspect the packaging. Avoid feeding your pet from cans that are swollen, leaking, severely damaged, or unusually bulging. These can indicate that the packaging seal has been compromised or that something has gone wrong with the product. Small cosmetic dents aren't always a problem, but damage around the seams or lid deserves extra caution.

When in doubt, don't feed it.

You can also check the food itself after opening. If you notice an unusual smell, unexpected color, abnormal texture, mold, or anything else that looks noticeably different from how the product normally appears, it's safest not to serve it.

Does Wet Pet Food Need to Be Refrigerated After Opening?

Once a can, tray, pouch, or other package of wet pet food has been opened, the unused portion should be refrigerated promptly. Opening the package exposes the food to air and microorganisms in the surrounding environment. Wet food also contains considerably more moisture than dry kibble, creating conditions where microorganisms can multiply more readily if the food is left at room temperature for too long.

Cover the remaining food before placing it in the refrigerator. You can use an appropriately fitted can lid or transfer the food to a clean, airtight food-storage container. Covering the food also helps prevent it from drying out and absorbing odors from other foods in your refrigerator.

How Long Does Opened Wet Pet Food Last in the Refrigerator?

Always follow the storage instructions provided by the pet food manufacturer, as recommendations can vary by product and packaging. As a general rule, refrigerated opened wet pet food should be used within a few days, rather than being kept for an extended period.

Many manufacturers recommend consuming opened canned pet food within approximately 3–5 days when properly refrigerated, although some products may have different instructions. For this reason, the directions on your specific product should take priority over a general guideline.

If you regularly feed only a small amount of wet food at each meal, consider choosing smaller cans, trays, or pouches. This can make portioning easier and reduce the amount of opened food that needs to be stored.

How Long Can Wet Dog or Cat Food Sit Out?

Once wet food has been placed in your pet's bowl, it shouldn't stay there indefinitely. Wet food exposed to room temperature, saliva, air, and environmental microorganisms can spoil more quickly than dry food.

A practical approach is to serve an amount your pet can finish during its normal mealtime and remove leftovers afterward. As a conservative food-safety practice, don't leave wet pet food sitting at room temperature for more than about two hours. In particularly warm environments, it should be removed sooner. This is especially important during hot summer weather or in homes without air conditioning.

Rather than filling the bowl with a large amount of wet food for your pet to eat throughout the day, serve smaller, fresher portions at regular mealtimes.

Can You Put Leftover Food From Your Pet's Bowl Back in the Can?

It's better not to mix food that has already been served with the clean, unused portion remaining in the original container. Once your pet starts eating, saliva and environmental microorganisms can be introduced into the food. Instead, portion out only what your pet is likely to eat. Keep the untouched portion covered and refrigerated separately. Using a clean spoon for each serving is another simple habit that helps minimize contamination.
