High-quality cat food bags have been designed to keep out the elements and maintain its freshness for as long as possible. Keeping the cat food bag also has the added benefit of retaining the cat food’s barcode, expiration date, and batch code – all of which are important information to have, especially in the event of a cat food recall.

Sealing the cat food bag after every feeding helps prevent unnecessary exposure to air and humidity — both of which speed up the rate at which pet foods degrade and increase the risk of bacterial contamination like Salmonella.

Exposing the cat food bag to sunlight can elevate temperatures and humidity inside. This will also speed up food degradation and increase the risk of Salmonella contamination as well as other bacteria.

Cat food expiration dates (sometimes known as “best by” or “use by” dates) are established to ensure the safety of your cat. Don’t take the risk by feeding your pet expired cat food.

You may be tempted to transfer that last bit of cat food from the old bag to a new bag. Don’t! You may be unknowingly tainting your brand new bag of dry cat food.
