Dry Cat Food Going Stale

Just how fresh is the dry kibble you feed your cat?

Even though dry kibble stays fresh longer than wet food, it still has an expiry date.

So how long can dry cat food stay out before it goes rancid and loses its nutritional value?



🐶 Fun Fact

Dry Kibble was invented in the mid 18th century to replace the more expensive wet food. They packed kibble in plastic bags to free up metal for use in the Civil war.



Dry kibble goes through an intense heating process to keep it dry for long.

This prevents bacteria from multiplying hence keeping the kibble fresh.

So does this mean dry cat food cannot go bad?

Dry cat food has an expiry date as well.

But how you handle dry kibble determines whether it stays fresh for long or goes stale quickly.


What makes dry cat food go bad?

Dry cat food oxidizes when left out in the open.

This causes the dry kibble to develop a stale taste and eventually rot.

Proper storage of dry cat food can slow down this oxidizing process and maintain the quality of the kibble.


How do I store dry cat food?

What makes dry cat food go bad

There are several ways to store dry cat food and ensure it remains fresh for longer.

Fortunately, we also have dry cat food that comes without an expiry date.

These are the freeze-dried versions that remain fresh for longer periods.


But if you go for normal kibble with a best before date, you have three ways of storing it;

  • Ziplock bags
  • Airtight containers
  • Freezing cat food


Ziploc bags

Once you open dry kibble, it is recommended that you store it in ziplock bags.

Ziploc bags keep oxygen out and ensure the kibble does not go rancid.

Once you put the kibble inside the Ziploc bag, squeeze out the edges to remove air before storing it.

Also, always ensure there are no tears or openings on the bags that will let air in.


Airtight Container

Airtight containers are stronger and more durable compared to ziplock bags.

They are also easy to seal and open anytime.

Ensure the Tupperware containers you buy are labeled as airtight.

Some containers leave out spaces around the lid that let air in.

Freeze your kibble

Freezing dry cat food is ideal if you still want to maintain the original packaging.

Freezing prevents bacteria from growing and making the kibble stale.

Ensure you thaw out the kibble before serving it to your cat.

Huge chunks of frozen kibble can easily choke a cat.


One more thing…

Make sure the kibble bag is not damaged when you get it off the shelf. As you read the label, also inspect the packaging for any wear and tear.


How do you buy the best dry cat food?

How long can dry cat food stay out will also depend on the date you buy it.

Most pet parents take a quick glimpse at the expiry date before tossing the product into the checkout basket.

But there is something pet food stores are not letting you know.




Dry cat food remains fresh 6 months after the Best Before Date. Some pet stores mark down their dry food products 3 months before this date.



Dry cat food products are marked down three months before the ‘Best Before Date’.

Though the discounted price allows you to stock up on cat food, you also have to know that their expiry date is drawing closer.

Unless you are raising several cats at home, most of this cat food will go bad before you even use it.
