Do Indoor Cats Need A Different Type Of Food To Outdoor Cats?

Clearly indoor and outdoor cats are not hugely dissimilar – they are both cats and share the same basic requirements, they need food rich in protein with the correct balance of vitamins and minerals. 

However, both their lifestyles are quite different and that means they need a dietary intake that is optimized for their lifestyle to get the most from life. Here are some of the key differences that have led to different food formulations for indoor cats :

Indoor Cats Burn Fewer Calories 

Outdoor cats, male and female, simply move more than indoor cats. Male cats can have wide-ranging territories that they naturally patrol and even female cats will patrol territories, albeit smaller than males. 

Then there is the fence jumping, wall walking, sprints from dogs/cars/other cats, catfights and other activities that outdoor cats get up to that burn calories. Add outdoor temperature variation into the mix and the calorie cost of keeping warm and it is easy to see how outdoor cats get through more calories than a cossetted, space-restricted indoor cat. 

If you gave an indoor cat food formulated for an outdoor cat they would soon get a bit chubby and need a diet to get healthy. To avoid such issues indoor cat foods are usually specially formulated with fewer calories per portion but with all the nutrients, vitamins and minerals your cat will need and with enough bulk to feel satisfied from eating whilst living the easy life…

Indoor Cats Generally Get More Hairballs

Indoor cats are more prone to hairballs than outdoor cats. The reason for this is that they don’t experience temperature variation through the seasons as an outdoor cat would experience. The result of this lack of exposure is that they continuously shed fur rather than having a seasonal shed as an outdoor cat would have. Because they are continuously shedding and grooming they naturally ingest more hair and are prone to developing more hairballs.

The problem is exacerbated by a sedentary lifestyle and excess weight. Cats with a sedentary lifestyle and weight problems tend to have less motile digestive systems. Basically, moving freely, gets your guts going and in cats, this means excess hair can pass through the system. 

In indoor cats, lack of exercise and weight gain can slow things down leading to blockages and promoting the removal of excess hair from the system via hairballs rather than through defecation.

To counter these additional hairball issues that come from an indoor life, indoor cat foods are often formulated with extra fiber to get the digestive system active and moving and reduce the chances of hairball issues.  Extra fiber can also help with weight management by moving food through the system before it is fully digested and by promoting feelings of satiety.

Indoor Cats Toilet Indoors

Because indoor cats toilet indoors, odor and volume of defecation become an issue for owners. To overcome odor issues, indoor food formulations often contain more fermentable fibers. Beet pulp, pectins, and guar gum are fermentable fibers that are often used in indoor cat foods to reduce odor issues and keep the guts moving efficiently.

When it comes to stool volume the only way to reduce output is to use food blends that are highly digestible. Digestible ingredients are the real meat products in the food rather than carbohydrate fillers or byproducts. Obviously, food formulations with the highest quality ingredients are often the most expensive – low priced foods might not reduce stool production to the same degree!

Dry vs Wet Cat Food

So your indoor cat needs fewer calories, more fiber and preferably, although not essential, higher quality digestible ingredients. Does this limit your choice to either wet or dry food? Well no. You can use either or. There are good choices that are suitable for indoor cats from both categories. Indeed, many owners use both wet and dry food with their indoor cat.

However, each type of food has its benefits and drawbacks. Here are some benefits and issues of using dry food for your indoor cat :

Dry Food Doesn’t Spoil Quickly

Wet food tends to dry up and go crusty if left out for a few hours. Cats can be pretty picky when it comes to flavor and texture, so stale wet cat food is often rejected by kitty. Dry food kibble can be left out without problems for days at a time which can work well for some owners who are out all day. If you like to let your cat graze through the day then dry food is a good choice. 

Better For Portion Control

For indoor cats who might be prone to weight gain, portion control is imperative. Dry kibble is often much easier, cleaner and straightforward to measure out on scales or in a cup than wet food. This lends itself very well to weight management in your cat and makes it easy if you have an overweight cat to gradually introduce them to a smaller diet.

Easy To Use With Puzzle Feeders

Your indoor cat is likely to be understimulated mentally compared to outdoor cats that are dodging cars, other cats and making their way in a dangerous world. You can try all sorts of things as an owner to keep them occupied and mentally active – you can use regular play sessions, get cat trees that stand near to windows to provide viewing platforms and various toys. 

Problem is that indoor cats can be so bored that they compensate by eating to relieve boredom. This leads to issues with weight gain. A good way to mentally stimulate a cat and slow down their eating is to get a cat puzzle feeder bowl. These bowls work best with dry food that often needs to be pawed out of the feeder. The majority of slow feed bowls just don’t work cleanly or well with wet food.

Dry Food Is Usually Cheaper Per Calorie

Maybe you think I am going to slam dry food as consisting of cheap, low-quality ingredients? Nope, the reason dry food is cheaper is the packaging. Less canning, fewer labels, bigger single bags. This is why, generally speaking, dry cat food is cheaper than wet food. That 8kg sack is just lighter on packaging costs that a 24 can tray of 3oz cans. However, that is not to say that some inexpensive dry foods are not packed with cheap, low-quality ingredients!

Beware, Large Bags Of Dry Food Spoil

As an owner, when you use dry food you just assume it will last as long as needed – surely that was the point of drying the food out? We would be wrong. Once you have opened a bag of dry cat food the clock is ticking – you have about 6 weeks before the nutrients in the food begin to degrade and your cat loses the benefits. With this in mind doing go buying a bumper-sized sack unless you are feeding a ravenous mob of kitties! Although you might get special deals on bigger packs it might not be the best option in a one cat home!

Dry Is Not Good For Hydration

Clearly, dry food is not great for hydration. Your cat has a rubbish thirst response. They simply don’t pick up on how thirsty their body is until it is nearly too late – this is a useless throwback to their desert living origins that does more harm than good in the modern world. 

In the natural environment, a cat would get most of their moisture from food rather than drinking liquid water. If you feed your cat dry food you need to make sure they are making up for the moisture loss elsewhere. You could try damping down the dry food or encouraging more water drinking using something like a cat fountain. Either way, a cat on a dry diet can easily suffer from hydration issues that a cat on a wet diet would not.

Most owners do a mix of both types of food to get benefits of both, for example, they feed their cats dry food during the day when the owner is out and then wet in the evening to balance out and make sure hydration is good.

Ingredients To Look Out For In Dry Cat Food

If you are going to go ahead and feed your indoor cat dry food it can be useful to understand what the food is made up of so you can identify food with cheap ingredients from high-quality food. These are some of the higher quality ingredients you should be looking out for and some you should avoid :

Highly Digestible Proteins 

Your cat needs a diet rich in protein to maintain muscle mass and stay healthy. But not all proteins are equal. Cat food often contains animal and plant proteins. Animal proteins are usually the best for your cat as they break down into usable amino acids more readily, however, animal protein is usually more expensive than plant protein. 

Even if your choice of cat food contains animal protein it may not be that useful if it is not in the form of digestible protein. Digestible protein is a protein that comes from good cuts of meat like chicken breast or animal muscle. Non-digestible animal protein such as animal byproduct or derivatives are unlikely to be bad or dangerous for your cat but they are not likely to be digestible enough to provide the amino acids your cat needs. Beware this stuff can bulk out the protein numbers on the packet and therefore the price without really helping your cat. 

Then there are meat meal products that come under the banner of animal protein. These meal products often contain crushed bone content that bulks up ash content numbers and reduces the amount of total digestible protein. 

All in all, the more digestible protein, the better for your cat’s health. Additionally, your indoor cat will have a smaller stool volume as they are digesting more of the nutrients from the food.     


Fats in cat food will make the food taste better to your cat as well as providing energy, lubricating the digestive system helping with hairball issues and a pathway for fat-soluble vitamins that your cat needs in its diet (vitamin K, A, D, E). Additionally, fats are a source of fatty acids in the form of omega 3 and 6. These fatty acids are required to manage inflammation, fight infection, maintain heart health and boost skin and coat condition. 

Your cat/kitten needs the fat content of dry food to be a minimum of 9% to provide for its basic needs. High-quality fat is preferred – herring oil, salmon oil, flaxseed oil, canola oil, pork fat, poultry fat, egg yolks, sunflower oil and soybean oils. Low-quality fats such as beef tallow or lard are to be avoided if possible. 


As there is very little moisture in dry food compared to a cat’s natural diet, dry indoor cat food will often contain a quantity of fiber within its ingredients. This fiber is not really a natural component in a wild cat’s diet. A wild, hunting cat would eat a very moist diet that also featured fur, feathers, ligaments, and bones which would be indigestible material that would help keep the cat’s digestive tract motile along with the moisture – fiber in dry cat food aims to replace this natural stuff.

Fiber is an indigestible carbohydrate – this means it is going to pass through the digestive system without being absorbed by the cat. Fiber is really useful for indoor cats who don’t get to hunt or eat wet cat food. Plant fiber will keep their digestive tract moving healthy which helps prevent hairballs and it also helps prevent the absorption of some glucose material which is generally bad for cats and can lead to diabetes and weight management issues.

Many owners see fiber listed in cat food and just assume it is a bulking agent or some cheapo ingredient. In indoor cats, fiber helps their quality of life by keeping them regular, reducing hairballs and helping with weight maintenance issues. 

The best sources of fiber are usually non-grain for hairballs (pectin, guar gum, pea, cellulose powder)

Digestible Carbs 

You want to avoid digestible carbs where possible. These carbs give rise to diabetes and weight management issues in indoor cats. They are also really unnatural in a cat’s diet and can end up giving your cat sensitivities either at first contact or after a pattern of use. Unfortunately, these carbs are often used in dry cat food to bulk, bind and fill the food out at low cost. 

What we are talking about here is anything like wheat, corn, soy, or fruit and the like. Some manufacturers spin the “it’s good for your cat’s vitamin and mineral intake” bullshit, but honestly, no one ever saw a cat eating an apple, carrot or cob of corn out of choice – it is a cheap fill that is unnatural to your cat’s digestive system. Avoid if possible, and minimize at all opportunities.
