How Long Does Dry Cat Food Last Once Opened?

How long does dry cat food last once opened? Dry cat food can last up to two years after it has been opened. This is because the ingredients are primarily dehydrated.

The moisture in the air will cause the food to turn into a solid-state, making it difficult for bacteria or other microorganisms to grow on it.

This means your dry cat food is safe to use for at least two years after opening and can be kept at room temperature.

Some cats (and people, for that matter) prefer to ‘break into a new bag of kibble before transitioning their pet over to eating solely from said bag. This leads to the food being exposed to air and, therefore, begins ‘going bad.’

If you notice that your cat doesn’t like a particular flavor or brand of kibble, it’s best to transition them over as quickly as possible. It is easier for some cats to accept a new type of food if they are introduced before their current supply runs out.

Some cats may refuse to eat their old food if mixed in with the new, so you need to transition them over before both types of food run out.

If you are purchasing different flavors and your cat isn’t eating one of them, try putting a little bit at the bottom or top of their bowl (depending on how picky they are) to see if they will eat it.

How do you store dry cat food after opening?

Moreover, some products have a special seal under which the remaining portion cannot be accessed, and it will not open if you try to pierce it with a fork or knife.

It is worth noting that all types of cat food should always be kept away from moisture and at room temperature. It will extend its service life and reduce the growth of microorganisms and prevent souring or maturation.
