The can of cat food is frequently not finished by cats in one sitting. Sometimes owners are too busy or forget to pick up the uneaten portion.
Use canned cat food safe for cats?
How long canned cat food can be kept out depends on the room’s temperature. In the summer, if there is no air conditioning, keep the meal out for no longer than 20 minutes. If the heating is on or the meal is typically in a warm kitchen, the same 20-minute time limit would still be in effect during the winter. The ultimate limit would be close to 30 minutes under ideal circumstances.
Kittens will likely finish their meal far before the quarter-hour mark because they require smaller, more frequent meals. It’s better to give them a spoon or two less every three hours than to risk giving them spoiled food.
The Effect of Air Exposure on Cat Food
Inhaling air exposes one to pathogens as well. Keep the food storage container as sealed as you can because moisture in the food may cause mold to grow. Another problem is the storage area’s temperature. Pet food shouldn’t be kept in a shed or garage where the temperature might rise above 100 degrees Fahrenheit, not even unopened bags or cans. Manufacturers generally suggest storing canned and kibble food in a cold, dry place. Using the kitchen pantry or an inside closet works great.

Refrigeration
Food should be covered and placed in the refrigerator as soon as it is opened in a can. The next serving can be heated up because most cats detest eating cold food. Food leftovers can be stored in zip-top plastic bags. They can be rapidly warmed in the sink with some running water for a few minutes. The subsequent serving could also be made in a dish that can go in the microwave, wrapped in plastic, and heated for a few seconds. Instead of making the dish hot, the objective is to warm it to room temperature.
