Just like human food, cat food should be stored properly or your cats can get sick.
Here are tips from PetMD:
1.Keep the original packaging
The cat food bag is designed to keep out the elements and maintain the freshness of the food for as long as possible. The bag also contains the expiration date, barcode, and batch code which are important if there is a cat food recall.
2.Never mix old cat food with new cat food
You may taint the new food with the old cat food. Put the old food in another container instead and feed this to your cat first.
3. Keep cat food away from sunlight
Sunlight can elevate temperatures and humidity, thus, it can speed up food degradation and increase the risk of Salmonella or other bacterial contamination .
4. Do not expose the food to air
Seal the cat food bag after every feeding to prevent unnecessary exposure to air and humidity which can speed up the rate of food degradation and also increase the risk of bacterial contamination like Salmonella.
5. Throw away expired cat food
Expiration dates are put on the packaging to ensure that the food is still safe for consumption by your cat. Never risk your cat’s health by giving expired food.
