Can I Heat Up Canned Cat Food In Microwave?

You can warm canned cat food in the microwave, but some precautions must be taken. Cats prefer warm food because it resembles freshly caught prey’s temperature, which appeals more to their instincts.

The ideal temperature for serving cat food is around body temperature, approximately 100°F (38°C), similar to the temperature of a mouse, their natural prey. This temperature is warm to the touch but not hot, ensuring it’s safe and enjoyable for your cat.

Transfer to a Microwave-Safe Dish

Begin by scooping the canned cat food out of its original container and into a microwave-safe dish. This is crucial because canned containers are not designed for microwaving and can release harmful chemicals or metals. Use a spoon or spatula to gently spread the food evenly in the dish. This ensures uniform heating and prevents cold spots.

Microwave in Short Bursts

Place the dish in the microwave and heat it in short bursts of about 5 to 10 seconds. This gradual heating helps avoid overheating and maintains the nutritional integrity of the food. After each burst, pause to stir the food gently. This step is important as microwaves can heat unevenly, and stirring helps distribute the heat throughout the food.

Check and Adjust Temperature

After microwaving, let the food sit for a few seconds to cool down slightly. Then, test the temperature by touching the food. It should be warm, not hot, roughly around 100°F (38°C), similar to the body temperature of a mouse. If it’s too hot, let it cool for a bit more. If it’s too cool, heat it for a few more seconds. This step ensures the food is at a safe and appealing temperature for your cat.

Serve with Care

Once the cat food has reached the desired temperature, place it in your cat’s feeding area. Always observe your cat’s reaction the first time you serve warmed food. Some cats might be hesitant initially if they are not used to warm meals. Encouraging them gently and giving them time to adapt to the new temperature of their food is key.

Drawbacks of Warming Canned Cat Food in a Microwave

  • Uneven Heating: Microwaves can heat food unevenly, creating hot spots that might burn a cat’s mouth and cold spots that are less appealing.
  • Nutrient Loss: Excessive heating can lead to the degradation of some nutrients, reducing the nutritional value of the food.
  • Change in Texture: Heating cat food in a microwave can sometimes alter its texture, making it less palatable to some cats.
  • Overheating Risk: There’s a risk of overheating the food, which can make it too hot for the cat to eat comfortably or safely.
  • Plastic Contamination: If the food is heated in a non-microwave-safe container, it can lead to the leaching of harmful chemicals from the container into the food.

Other Methods to Heat Canned Food

Food Warmers

Food warmers are a gentle and safe way to heat canned cat food. These devices often come with temperature controls, allowing you to set a specific warmth level. By placing the cat food in a dish on the warmer, it gradually reaches the desired temperature without the risk of hot spots. This method is especially beneficial for keeping the food at a steady, warm temperature over a period, ideal for cats who graze throughout the day.


Using steam to warm canned cat food is a gentle method that preserves nutrients and maintains moisture. You can achieve this by placing the cat food in a heat-resistant dish over a pot of boiling water (in a steamer basket or similar setup), ensuring the dish doesn’t come into contact with the water. The steam heats the food evenly and gently, avoiding the risk of overheating and nutrient loss. This method is particularly useful for heating larger quantities of food uniformly.

Frequently Asked Questions

Do cats like warm or cold food?

Cats generally prefer their food at room temperature or slightly warm, as it’s closer to the temperature of their natural prey. Warm food also tends to be more aromatic and appealing to cats, enhancing their appetite.

Is it okay to feed a cat cold food?

Feeding a cat cold food is generally safe, but it might be less appealing to them. Some cats may hesitate to eat cold food, especially if they’re accustomed to food at room temperature or warmer.

Can I add warm water to wet cat food?

Yes, you can add warm water to wet cat food. This can enhance the food’s aroma and make it more appealing. It also helps increase your cat’s water intake, which benefits their hydration, especially for cats prone to urinary tract issues.

Can I thaw frozen canned food in the microwave?

You can thaw frozen canned cat food in the microwave, but it should be done cautiously. Use a low power setting and heat in short bursts, stirring in between, to avoid cooking the food or creating hot spots. It’s crucial to ensure the food reaches room temperature before serving it to your cat.
