Introduction
Proper storage of canned cat food is important for maintaining freshness and nutritional value. Canned cat food comes in aluminum cans or pop-top containers which are sealed to prevent contamination and spoilage. However, once opened, canned food requires refrigeration. There are some guidelines to follow for pantry and refrigerator storage as well as signs of spoilage to watch out for. Proper storage helps retain nutrients, avoids waste, and prevents foodborne illness. This article provides an overview of recommendations for storing unopened and opened canned cat food.
Dry vs Refrigerated Storage
There are two main methods for storing canned cat food – keeping it at room temperature in a pantry or cupboard, or refrigerating it after opening. Both methods have their pros and cons.
Storing canned food at room temperature is convenient, as you don’t have to worry about transferring it in and out of the fridge. The food also retains its aroma and texture better at room temperature. However, keeping opened canned food unrefrigerated reduces its shelf life due to bacterial growth at higher temperatures. For room temperature storage, the shelf life is 2-3 days after opening for wet food and 4-6 weeks for dry food. [1]
Refrigerating canned cat food can extend its shelf life considerably. Wet food will stay fresh for 5-7 days when refrigerated, while dry food can last 2-3 months. [2] The cold temperature suppresses bacterial growth. However, refrigeration can dull the taste and aroma of the food. Some cats may also be reluctant to eat chilled food.
In summary, room temperature storage provides convenience and flavor preservation at the cost of reduced shelf life. Refrigeration extends shelf life significantly but may alter the food’s palatability.
Pantry Storage Tips
When storing canned cat food in the pantry, it’s important to keep some guidelines in mind to maintain freshness and quality. Ideal pantry conditions for canned cat food storage include:
- A cool, dry place. Temperatures between 50-70°F are best.
- Low humidity. Moisture can lead to can corrosion.
- Good airflow. Stagnant air can cause odors.
- Clean surfaces. Wipe down shelves regularly to avoid dust buildup.
- Away from heat sources like ovens or dishwashers.
- Out of direct sunlight, which can affect nutrients.
Storing cans in airtight, rodent-proof containers is also recommended. Use containers made of materials like plastic, glass, or stainless steel. Some pet owners opt for specialty dispensers that neatly store and dispense cans (Source). Wherever you store cans, be sure to keep the area organized and check expiration dates regularly.
Refrigerator Storage Tips
The ideal temperature range for storing opened canned cat food in the refrigerator is 35-40°F. This helps slow bacterial growth and keeps the food fresh for longer. According to veterinarians, refrigerated wet cat food will stay fresh for 5-7 days after opening the can (source).
Make sure to place opened cans on a shelf rather than the door, which tends to be warmer due to frequent opening. Store cans upside down if possible, to create a tighter seal and prevent leaks. Transfer any uneaten food into a sealed container, covering it fully to limit air exposure. Glass and plastic containers with tight-fitting lids work well.
It’s ideal to let refrigerated cat food reach room temperature before serving, which usually takes around 20-30 minutes. Microwaving cold food can reduce its nutrient content. Gently stirring the food can speed warming.
Shelf Life
The shelf life of canned cat food depends on whether it is stored in the pantry or refrigerator. Unopened canned cat food that is stored in a cool, dry pantry will typically last 2-5 years past the “best by” date printed on the can [1]. Once opened, leftover canned food should be transferred to a sealed container or plastic wrap and refrigerated. Refrigeration can extend the shelf life for 3-5 days after opening [2]. Keeping canned cat food refrigerated helps slow bacterial growth and maintain moisture, texture, and nutritional content.
In comparison, storing opened canned cat food in the pantry or at room temperature can allow bacteria to multiply rapidly. Pantry storage limits shelf life of opened canned food to just 2-4 hours before unsafe bacterial levels develop [1]. So for food safety and quality, refrigerate any leftovers promptly in a sealed container.
Signs of Spoilage
When evaluating whether canned cat food has spoiled, there are a few key signs to look out for. According to Petslunch.com, one of the most apparent signs is a foul or unpleasant smell emanating from the can [1]. Canned cat food should have a neutral smell or smell like meat. If it gives off a rancid, sour or ammonia-like odor, it has likely gone bad.
You’ll also want to closely inspect the appearance of the cat food. According to AdoptandShop.org, any abnormalities in the look of the food, such as unnatural colors or textures, indicate it is spoiled [2]. The food should retain its natural colors and consistency. If it looks mushy, slimy or moldy, it should be discarded.
Lastly, if your cat refuses to eat the canned food, this could signify it is no longer fresh. Trust your cat’s instincts – if the food smells or tastes ‘off’ to them, it’s best not to serve it.
Food Safety
Properly storing canned cat food is crucial for preventing bacterial growth like Salmonella and Listeria, which can make cats sick. Once opened, cans should be refrigerated and used within 2-3 days. Leftovers should be discarded after this time period.1
It’s especially important not to leave open canned food out for more than 30 minutes, as bacteria can multiply rapidly at room temperature. Store opened cans covered in the refrigerator, rather than leaving them in the can. Portion meals into separate containers to limit exposure. Thoroughly clean any dishes, cans, or utensils that contact the food.1
Don’t feed cats anything that smells bad or looks spoiled. Signs of spoilage include mold, clumping, unnatural color changes, or a rancid smell. When in doubt, throw it out to be safe. Freezing cans can extend shelf life, but they should be thawed gradually and used within a few days.1
Transitioning Storage Methods
When transitioning canned cat food storage between the pantry and refrigerator, it’s important to do so gradually to avoid upsetting your cat’s digestive system. Here are some tips:
- If switching from pantry to refrigerator, start by chilling the can for 30 minutes before serving. Over the course of a week, increase the chilling time until storing overnight in the fridge.
- If switching from refrigerator to pantry, do the opposite. Start by taking the can out of the fridge 30 minutes before serving. Over a week, decrease the amount of time in the fridge until storing at room temperature.
- Mix small amounts of chilled food with room temperature food when transitioning. This helps your cat get used to the temperature change gradually.
- Warm refrigerated food to room or body temperature before serving. Microwave 5-10 seconds or place the opened can in warm water.
The key is to transition storage methods slowly. This gives your cat time to adjust to changes in food temperature and texture. Rushing the process can upset their digestive system. For more tips, check out this helpful video: How to Store Wet Cat Food.
Special Circumstances
When storing canned cat food for multi-cat households or cats with special needs, there are a few additional factors to consider:
Multi-Cat Households
With multiple cats eating from the same cans, it’s important to divide up portions and close the can tightly between feedings. This prevents contamination and maintains freshness. Consider investing in portion control containers to divide up meals. Refrigeration is preferred for households with more than 2 cats.
Kittens
Kittens have smaller stomachs and need to eat more frequently. Opened cans should be refrigerated and consumed within 2 days. When possible, look for single-serve kitten-sized cans.
Senior Cats
Some senior cats are prone to poor digestion or may struggle with chewy chunks in canned food. Refrigerating open cans keeps food easier to digest and high-moisture content optimal. Plan portions for 1-2 days max to ensure freshness.
Summary
To summarize, canned cat food can be safely stored either in the pantry or the refrigerator depending on your preference and your cat’s needs. Unopened canned cat food will keep for 2-5 years in the pantry, while refrigerating can extend its shelf life even longer. Once opened, refrigerate any unused portions in a sealed container, and use within 2-3 days. Regardless of storage method, check for signs of spoilage like swelling, leaking, bad smell or appearance before feeding. With proper storage, canned cat food can stay fresh and safe to feed your cat. The key is keeping it in a cool, dry place and practicing good food hygiene.
