Should Kitties Graze? The Pros and Cons of Free-Feeding Dry Cat Food


Leaving dry cat food out all day, also known as free feeding, is a common practice among cat owners. However, it’s a controversial topic with valid arguments on both sides. Understanding the pros and cons of free feeding is important for cat owners to make an informed decision about the best feeding method for their pet.

On one hand, free feeding can be convenient, allowing cats to eat whenever they feel hungry. It mimics their natural grazing behavior in the wild. But on the other hand, some experts warn that free feeding can lead to overeating and obesity in cats. It also makes it difficult to monitor your cat’s food intake and notice any changes in appetite that could signal health issues.

There’s no definitive right or wrong answer. The best feeding method depends on the individual cat, their age, activity level, health conditions, and whether there are other pets in the household. Weighing the benefits and risks allows cat owners to choose what will work best for their feline companion.

Benefits of Leaving Food Out

Leaving dry food out all day offers some potential benefits for both cat owners and their feline companions:

For cat owners, leaving food out provides convenience, as they don’t have to adhere to strict feeding schedules or worry about constantly refilling the food bowl throughout the day. Many owners with busy work schedules find this free-feeding approach easier to manage.

For cats, having food available all day means they can eat whenever they feel hungry. This aligns with a cat’s natural inclination to eat multiple small meals throughout the day and night. With food always accessible, cats are less likely to beg or meow insistently for meals.

Cats who graze freely also gain a sense of control and independence around feeding time. This can reduce anxiety and stress for some cats prone to food insecurity. Cats who prefer to nibble frequently may do better health-wise when allowed to eat at will.

Overall, the free-feeding approach offers simplicity and flexibility for owners, while allowing cats to follow their natural grazing instincts. This can minimize conflicts at mealtimes.

Risks of Overeating

Leaving dry food out all day provides cats constant access to food, which can lead to overeating and obesity. According to research from the National Center for Biotechnology Information, obesity is a risk factor in the development of feline diabetes, liver disease, and urinary tract infections.

The carbohydrates in dry cat food can contribute to obesity, as cats have difficulty digesting carbs and tend to overeat these calorie-dense foods. A study cited by Affectionately Cats found the risk of feline diabetes increases by 80% for overweight cats. Diabetic cats unable to regulate their blood sugar can develop serious complications.

Excess carb intake also stresses the liver, potentially leading to hepatic lipidosis, especially when combined with rapid weight loss. Liver disease impairs the body’s ability to metabolize nutrients and remove toxins.

Finally, urinary tract infections resulting from concentrated urine and bladder crystals have been linked to dry food diets. UTI symptoms like bloody urine, straining, and frequent trips to the litter box can indicate potentially dangerous urinary tract blockages.

Suggested Feeding Routines

Many cat owners find success using scheduled mealtimes throughout the day to feed their cats. This allows the owner to control portions and monitor their cat’s food intake and health. According to the Cornell Feline Health Center, most cats should be fed two or three times per day (1). Portion control is important, as overeating can lead to obesity. Follow your vet’s recommendations for the ideal amount of food for your cat based on weight, age, and activity level.

Using an automatic pet feeder can take the guesswork out of portion control. These feeders can dispense dry food at preset intervals, allowing the cat access to food throughout the day while controlling calories. According to Urgent Pet Doc, automatic feeders may help regulate a cat’s eating schedule (2). Just be sure the feeder dispenses an appropriate amount of food.

The key is finding a routine that works for your cat and lifestyle. Sticking to a regular schedule will help avoid overeating. As always, consult your vet if you have concerns about your cat’s diet and eating habits.

Cats’ Natural Eating Habits

In their natural environment, cats are predators who hunt and eat multiple small meals throughout the day and night. Cats are naturally grazing animals and instinctively eat 10-20 small meals per day. This allows cats to consume calories from hunting as prey becomes available in a natural setting, rather than eating just one or two large meals. According to IAm’s article, cats in the wild spend a significant amount of time hunting, foraging and working for their food. The process of hunting and capturing prey provides cats with mental stimulation and allows them to indulge their natural instincts.

With free choice dry food available all the time, cats are deprived of this natural stimulation. The easy availability of dry food takes away the work of hunting for meals. This can lead to boredom and associated behavioral issues over time. It’s healthier for cats to eat smaller meals distributed throughout the day to mimic natural grazing, rather than have unlimited access to dry food which provides little mental engagement.

Food Freshness

When dry cat food is left out all day, it can become stale and unappetizing over time. Kibble absorbs moisture from the air, causing it to lose its crunch and become soggy. Research shows that dry cat food generally stays fresh for about 6 months if unopened, but once opened it will start to degrade in quality and freshness rather quickly.

Another issue with leaving dry food out is that it can attract ants, cockroaches, and other insect pests. These insects can contaminate the food with bacteria, eggs, or feces. Consuming contaminated food puts cats at risk for intestinal parasites and other illnesses. To keep dry cat food tasting fresh and prevent bug infestations, it’s best not to leave it sitting out for more than a day.

Effect on Multiple Cats

Free feeding multiple cats can often lead to issues around dominance and access to food. As noted by Hill’s Pet Nutrition, dominant cats will tend to overeat when free-fed dry food is left out at all times. They do not regulate their intake well when given unlimited access and will keep eating whenever food is available1. On the other hand, timid or less dominant cats may struggle to get the food they need when a dominant cat is overeating. They can become undernourished since the dominant cat stakes out the food bowl and prevents them from eating.1

For households with multiple cats, it is usually recommended to transition away from free feeding. Feeding set meals a couple times a day, adjusting portions for each cat, allows better regulation of food intake. Cats should be separated at meal times to allow timid cats to access food without competition or intimidation from dominant cats.

Tips for Transitioning

Gradually reducing the amount of dry food left out for free-feeding is essential for a smooth transition to scheduled meal times, according to Food Fur Life. Start by leaving only 75% of the cat’s normal daily portion in the bowl during the day. Over the course of two weeks, reduce this to 50% and then 25% of the daily calories. Cats may resist at first, but be patient and stick to the plan. Once you are only leaving a small amount of food out, it will be easier to switch to distinct, scheduled feedings.

It’s also important to provide enriching activities during the periods when food is not available, notes WOPET. Make sure your cat has access to toys, cat trees, scratching posts, and windows with views of outdoor activity. Consider food puzzle toys that reward cats with small treats when played with. Engaging playtime with wand toys or laser pointers is also recommended. Keep your cat occupied and entertained between meals.

When Free-Feeding Makes Sense

Free-feeding may be appropriate for some cats in specific situations. This includes:

  • Kittens – Kittens have small stomachs and high energy needs, so they benefit from having food available at all times for frequent small meals. According to the ASPCA, free-feeding allows kittens to eat as much as they need to support growth and development.

  • Nursing cats – Nursing mother cats need access to plenty of calories and nutrients to support milk production. The Cornell Feline Health Center recommends free-feeding nursing cats high-quality kitten food so they can eat as needed.

  • Diabetic cats – For cats with diabetes being treated with insulin injections, it’s important to maintain consistent food intake. The Merck Veterinary Manual recommends free-feeding diabetic cats to stabilize blood glucose levels.

  • Underweight cats – Free-feeding can allow underweight cats to increase their food intake and regain lost weight. Veterinarians may recommend free-feeding along with high-calorie supplemental foods.

In these cases, free-feeding provides important health benefits for cats with increased nutrition needs. However, it’s still important to monitor portion sizes and use measuring cups to prevent overeating.


Leaving dry food out at all times has its benefits and downsides. On one hand, free feeding allows cats to eat whenever they feel hungry and fulfill their natural grazing tendencies. It’s also more convenient for owners who have busy or unpredictable schedules. However, this method can contribute to overeating and obesity in some cats, while also causing the food to go stale.

Ultimately, the right choice depends on your cat’s age, activity level, and self-regulation abilities. Kittens and inactive or overweight cats do better with scheduled, measured feedings to control portions. Healthy adult cats can often successfully free-feed dry food, as long as their intake is monitored. Just be prepared to transition to scheduled feedings if problems arise. Free feeding wet food is not recommended due to spoilage.

The best approach is usually a mix of both free feeding dry food and scheduled wet food meals. This provides cats the autonomy of grazing without overindulging, while still ensuring regular fresh meals. Pay attention to your individual cat’s needs and you can find a feeding routine that suits both of you. The key is being flexible and adjusting as needed to keep your cat healthy and happy.
