If unopened, canned cat food typically can be kept for quite a while. It is always best, however, to check the best by date on the can before giving the food to your cat. Throw out food that has passed its best by date, even if you recently bought it. If you just bought a can of cat food with an expired date, you can try to return it for a refund or exchange. Do not store the food in a location that exceeds 100 °F (38 °C) Exposing the cat food to too much heat and humidity can cause degradation in the food. Store the food in a location where it won’t be exposed to sunlight or water. Putting the food in your cupboard or pantry is ideal. It is okay to store food in a very cold location. This will not lead to degradation of the food. Even if you’ve stored the food properly, check the container before storing it. If you see that the packaging has been ripped, it is best to throw the food away. You should also throw out containers of food with visible mold or dampness. It is best to keep the food in its original packaging until you open it. After opening the food and storing it in an airtight container, do not throw the original packaging away. The packaging contains information you will need if the brand of food is ever recalled.
