Does wet cat food need to be refrigerated?

Yes, wet cat food needs to be refrigerated after opening. Keeping it cold helps prevent bacterial growth and maintains its freshness. Leaving it out at room temperature for too long can lead to spoilage and make it unsafe for your cat to eat.

Refrigerating wet cat food also preserves its taste and texture. It’s important to cover the opened can or pouch tightly before storing it in the refrigerator. Remember to check the expiry date and discard any leftover food that has been sitting in the fridge for too long to ensure your cat’s health and enjoyment.

How Does The Fridge Help Keep Wet Cat Food Safe?

The fridge keeps wet cat food at a temperature too cold for rapid bacteria growth. Most bacteria prefer room temperature to multiply. In the fridge, their growth slows way down.

The fridge temperature between 35-40 degrees Fahrenheit is not comfortable for bacteria. They cannot double as quickly in these cooler indoor fridge conditions. The bacteria take much longer to potentially spoil wet cat food inside the fridge compared to leaving it out.

Is The Best Way To Store Wet Cat Food In The Fridge

The best way to store wet cat food in the fridge is in a sealed container. A plastic container with an airtight lid works well. This seals out air and bacteria that could get inside.

Clearly label and date the container so you know when the wet cat food inside was first opened and refrigerated. First in, first out helps ensure the oldest food gets used first before newer batches.

Wet Cat Food Be Covered In The Fridge

Yes, wet cat food should always be covered in the fridge. An uncovered container allows fridge odors and bacteria to potentially get inside the wet cat food. Contact with open air promotes bacteria growth that refrigeration aims to slow down.

A covered container seals wet cat food away from outside germs. It best protects the quality and safety of the wet cat food inside the fridge until mealtime.

Wet Cat Food Last In The Fridge After Opening

Wet cat food stored in an airtight container in the fridge lasts 3-5 days after opening. On the third day, it starts getting close to the 5-day limit. After 5 days, the wet cat food quality declines and bacteria levels rise.

At 5 days, the wet cat food odor and texture may seem off. It’s best to discard any wet cat food in the fridge reaching the 5-day threshold to prevent tummy troubles for cats. Freshness keeps them happiest and healthiest.

Wet Cat Food Be Frozen For Later Use

Yes, wet cat food can be frozen to extend its safe storage time beyond just refrigerating. Freezing stops bacteria growth completely by lowering the temperature below freezing.

It’s best to freeze wet cat food in single meal portions using ice cube trays or mini containers. This allows pulling out just what’s needed to defrost for feeding time. Clearly label containers with the date before freezing for first-in, first-out use.
