Keep dry cat food in its original bag inside an airtight container, stored in a cool, dark, dry place, and use it within about four to six weeks of opening a large bag. Transfer wet food to a covered container and refrigerate it for up to three days. Heat, light, air, and moisture are what destroy freshness and nutrients, so the goal is to limit all four.
- Keep dry food in its original bag, then seal it.
- Store in a cool, dark, dry place.
- Refrigerate opened wet food, use within three days.
- Bin food that smells stale or looks mouldy.
How should I store dry cat food?
Dry food stays fresher when it is kept cool, dark, and sealed. The best method is to keep the food in its original bag, squeeze out excess air, and place the whole bag inside an airtight container. The bag is designed to protect the food, and the container adds a second barrier against air and moisture. Store it in a cupboard away from the oven, radiator, or a sunny window, since heat accelerates the breakdown of fats and vitamins. Do not pour food directly into a container and discard the bag, because you lose the batch number and best-before date, which you need if there is ever a recall. Keep the container clean and dry between refills, and avoid topping up old food with new, since that mixes stale kibble with fresh. Buy a bag size you can finish within about four to six weeks.

Should I keep food in its original bag?
Yes, whenever possible. The original bag is engineered to slow oxidation and moisture transfer, and it carries the batch code and expiry date you need for recalls and freshness checks. If you transfer food to a container, keep the bag inside it rather than emptying the kibble out. Many plastic containers are not fully airtight, and some can absorb and transfer odours and oils over time, which is why a clean, food-grade container with a tight seal works best. If you prefer a container for convenience, cut the label or write the batch number and date on the lid. Wash the container thoroughly between batches, and make sure it is completely dry before refilling, because residual moisture encourages mould. A simple routine of bag inside bin, sealed and dated, solves most storage problems.
How do I store wet food after opening?
Wet food spoils quickly once opened, so treat it like fresh food. If you do not use a whole can or pouch at one meal, transfer the remainder to a covered container and refrigerate it, then use it within about three days. Leaving opened wet food out at room temperature for hours is a common cause of stomach upset, so pick it up after about thirty minutes if your cat walks away. Do not feed food straight from the fridge if she turns her nose up at it, since many cats prefer it closer to room temperature, so let it stand briefly or add a little warm water. Never reheat wet food in a microwave, as it can create hot spots that burn her mouth. Unopened cans should be stored in a cool, dry cupboard and used by their best-before date, and dented or bulging cans should be discarded.
How long does cat food stay fresh?
Dry food is usually best used within about four to six weeks of opening a bag, even though the printed date may be months away, because exposure to air starts degrading fats and vitamins as soon as the seal is broken. A small bag finished quickly is fresher than a huge one that sits open for months. Unopened dry food keeps until its best-before date if stored cool and dry. Opened wet food keeps for up to three days in the fridge, and unopened cans keep until their date. Treats and toppers have their own timelines, so check the label. If you are unsure how long a bag has been open, write the opening date on it, which makes the decision easy. When in doubt, throw it out, because stale food offers less nutrition and can upset a cat’s stomach.

What are the signs cat food has gone bad?
Your nose and eyes are reliable guides. Dry food that smells stale, sour, or rancid, looks faded, or feels damp should be discarded. Clumping, mould, or tiny insects mean the food has been exposed to moisture and must be thrown away, and the container should be washed and dried before reuse. Wet food that smells off, has changed colour, or has dried and crusted at the edges is past its best, and any bulging or leaking can points to spoilage or a damaged seal. A cat who suddenly refuses food she usually likes may be telling you it has turned, so trust her. Do not try to mask stale food by mixing it with fresh, since that can make her avoid the whole bowl. Food safety matters because spoiled food can cause vomiting and diarrhoea, and repeated digestive upset is hard on a cat.
How do I store food for multiple cats or a big bag?
With several cats, you may be tempted to buy the largest bag, but freshness suffers. If you must buy in bulk, divide the food into smaller airtight containers, keep one in use, and store the rest sealed in a cool, dark place, so you are not opening the main supply daily. Label each container with the batch number and the date you opened it. For households with different diets, keep each cat’s food in its own labelled container to avoid mix-ups, and store medications and supplements separately from food. Portion out meals rather than free-feeding from a large bin, which keeps the food cleaner and lets you monitor each cat’s intake. A slow feeder can help if one cat bolts her food, and our guide to slow feeders for cats explains how to slow eating and reduce vomiting.

Frequently asked questions
- Can I store cat food in the fridge? Dry food should not be refrigerated, because moisture can spoil it. Opened wet food should be covered and refrigerated for up to three days.
- How long does an opened bag of dry food last? Aim to use it within about four to six weeks. Buy smaller bags if your cat eats slowly.
- Should I wash the food container between refills? Yes. Wash and dry it thoroughly, because leftover oils and crumbs can turn rancid and taint fresh food.
- Can I mix old and new dry food? Avoid topping up. Mixing stale food with fresh shortens the life of the whole batch, so finish one before opening the next.
- Is it safe to feed food past its date? No. Discard food past its best-before date or showing any sign of spoilage, since it may offer less nutrition or cause illness.
