Have you ever wondered why your cat never finishes his/her bowl of food, or even why your cat only takes a small bite and leaves the rest of the food? This is because cats are known for having inconsistent eating habits. As a cat owner, I noticed that my cat would eat a small portion of her food, but she would return later for another portion. It brought up questions such as, ‘can cat food be left out all day/night?’ and ‘how long can cat food be left out?’

Cat owners can leave their cat’s food out all day and night, but this only applies to dry cat food. Wet cat food tends to accumulate bacteria faster than dry cat food. There is a limit to how long you may keep out dry food, but it will ultimately last longer than wet cat food.

Cat owners can either use the free-feeding, meal-feeding, or combination(mixed) feeding method to feed their cats. Observing your cat’s eating habits will help you determine which feeding method is most suitable for your cat.

Is It OK To Leave Dry Cat Food Out All Day?

Many cat owners believe that it is perfectly fine for dry cat food to be left out all day. Cats usually do not finish their food and often return for more later in the day. Leaving out a bowl of food allows your cat to snack on the food throughout the day. There are high levels of carbohydrates and protein found in dry cat food. This allows the dry food to last longer than wet food while being left out in your cat’s food bowl.

Dry cat food is low in moisture, and this allows your cat to free-feed throughout the day/night without you having to worry about spoilage. You should make sure that you are purchasing quality dry cat food before trying out this feeding method. If you have a busy life, you might want to leave out dry cat food so that your cat is free to come and go. However, be careful because dry cat food may accumulate bacteria if left out for longer than a day.

How Long Can You Leave Dry Cat Food Out?

Dry cat food lasts longer than wet cat food, but there is a limit to how long you can keep the dry food out. The longer you keep out the dry cat food, the less tasty it becomes for your cat. It is advisable to replace the dry food after one day to ensure that you feed your cat with fresh, quality dry food. Some cat owners leave the dry food out for two days, but this approach may result in your cat not finishing the food.

Cat specialists suggest that practicing good hygiene for your cat involves getting rid of unwanted or remaining dry food. Thoroughly washing your cat’s food bowl also contributes to the fresh taste of the food. You may leave out dry cat food for a day or two but keep in mind that this type of food will become stale, resulting in the food being less appealing to your cat. We should have our cat’s interests at heart, and we can do this by providing them with fresh nutritional food.

What Is The Difference Between Free Feeding, Meal Feeding, And Combination(Mixed) Feeding?

Cat owners are usually confused when trying to decide which feeding method is best for their cats. There are three types of feeding methods that cat owners use: free-feeding, meal-feeding, and combination-feeding. The section above focuses more on the free-feeding method, but some cat owners follow the meal feeding method. Below is a short explanation of the three feeding methods as well as their respective advantages and disadvantages:


This method is the most common feeding method amongst cat owners. Free-feeding involves the cat owner leaving food in the cat’s bowl throughout the day and allowing the cat to eat anytime. This feeding approach should only be used with dry cat food because wet cat food is not meant to stay out for an extended period.

The advantage of this feeding method is that it allows cats to eat small meals right throughout the day. It also allows for flexibility without having to check if your cat has eaten anything for the day. The disadvantage of this feeding method is that it may lead to your cat overeating and potentially becoming obese. Using the free-feeding method makes it difficult to track your cat’s eating habits and appetite.


This feeding method is used by cat owners who want to control their cat’s diet and eating habits. The meal-feeding method involves the cat owner providing food only at specific times throughout the day. Dry cat food, as well as wet cat food, can be used in this feeding method. If you want to observe your cat’s appetite, this would be the best method.

The advantage of this feeding method is that it allows you to control your cat’s food portions so that greediness and obesity can be avoided. It also allows for you to have a household with multiple cats where all cats are fed equally. The disadvantage of this feeding method is that it lessens your flexibility due to needing to feed your cat at specific times of the day.

Combination(mixed) Feeding

This feeding method involves cat owners serving their cats wet cat food and dry cat food. In this feeding method, the dry food is freely available for the cat, while the wet food is served twice a day. Cat specialists suggest that cat owners that use this feeding method should consider using a food puzzle so that your cat plays with the food snacks while feeling a bit of a challenge.

The advantage of this feeding method is that it allows your cat to eat multiple small meals at their own time. You can still observe your cat’s eating habits and appetite by adding wet food to their meals. The disadvantage of this feeding method is that it may lead to overeating or obesity. If you have multiple cats, this feeding method will make it difficult for you to observe each cat’s total food intake.

Should I Leave Food Out For My Cat At Night?

Cat owners may leave food for their cats at night, but this should only be dry cat food. Wet cat food is not meant to be open for long, and therefore it would spoil overnight while attracting bacteria. Research suggests that leaving food at night may not work out if you have multiple cats. Below is a list of advantages to leaving your cat food at night:

  • Provides a sense of freedom between you and your cat
  • It gives you free time
  • Less worrying about whether your cat will go hungry overnight
  • Easy to manage
  • The perfect approach for dry cat food

Why Is My Cat Not Eating Even Though I Left Food Out The Whole Day?

Cats have inconsistent eating habits, and that is why you should not be surprised if your cat decides that he/she does not want to eat a specific type of food anymore. Keep an eye out for your cat’s eating habits so that you can help your cat regain an appetite. If your cat is still not eating then calling or visiting a vetenerian would be the next best option.

There are multiple reasons why a cat would stop eating. Health issues such as respiratory diseases, digestive system diseases, and dental diseases are some common issues that contribute to your cat not eating. Your cat might also not be eating because of food issues such as food flavor, food shape/texture, and food spoilage.


Cat food can only be left out for a full day or overnight if it is dry cat food. Wet cat food should not be opened for an extended period. Cat food will accumulate bacteria and become stale if you leave it open for longer than a day. Wet cat foods tend to deteriorate at a faster pace than dry cat food. To keep your cat healthy, you would have to feed him/her fresh food and make sure to clean the food bowl after a meal thoroughly.

There are three types of feeding methods that you can use to make sure your cat maintains a healthy and balanced diet. You would need to observe your cats eating habits and appetite to determine which feeding method will best suit your cat. Cat owners may leave food for their cats at night if it is dry cat food. Lastly, cats have inconsistent eating habits, and therefore you should check for health and food issues to regain your cat’s appetite.
