It's common to wonder what separates an "indoor" cat food from a regular one and whether it's truly necessary. Our vet-guide is here to help answer that question, decide if an indoor formula is right for your cat, and how to choose the best one.

What is indoor cat food and how is it different?

Indoor formulas are specifically designed for the lifestyle of a cat living exclusively inside. The primary difference is that they are typically lower in calories and fat. This is important because indoor cats are generally less active, making them more prone to weight gain and obesity. The controlled calorie content helps your cat maintain an ideal body condition.

Additionally, many indoor diets include higher levels of fibre. This serves two key purposes:

It helps your cat feel fuller for longer, which assists with weight management.
It promotes healthy digestion and helps reduce the formation of hairballs.

Finally, these formulas often contain specific ingredients to help neutralise litter box odours, creating a fresher home environment.

Four factors to consider when choosing an indoor food for your cat:

Health conditions: Your treating veterinarian should be your first port of call when it comes to dietary advice if your cat has any underlying diagnosed health conditions. In many cases, there may be veterinary prescription diets which are the best option to help manage your cat's condition. For health support, there are a range of non-prescription, retail diet options to help prevent common health conditions that indoor cats are prone to, such as hairball control.
Complete and balanced: In choosing a food, the most important consideration after any health factors is that the diet is complete and balanced for your indoor cat's stage of life. Ensuring that it meets AAFCO or FEDIAF pet food control guidelines is crucial to ensure that your cat receives all the nutrients they require in the correct ratios.
Age: Cats of different ages have very different nutritional requirements. Kittens require energy-dense food which meets their ongoing growth rates, while senior cats are often less active and have a slower metabolism which means that they require fewer calories and less fat, but an easily digestible diet, to help them maintain good body condition. There are many senior indoor diets available, which combine the benefits of both diets.
Quality: The quality of the ingredients and the digestibility of the nutrients they provide should be a key factor in choosing a food. Premium foods are designed to be highly digestible (which means smaller, firmer stools) and do not change ingredients batch to batch like grocery type brands, which means less tummy upsets. They also tend to contain higher levels of added beneficial nutrients, such as omega fatty acids for joint and coat health, and some are backed by testing to ensure they deliver the results they promise. Learning how to read pet food labels and understanding the ingredients in your cat's food are crucial parts of knowing what is the best food for them.

Factors to consider when feeding indoor cats

Do I feed a wet or dry indoor food?

Many indoor diets are conveniently available in both a dry and wet food variety - and the best thing is to feed both! Dry food is more calorie-dense than wet food and has the added mechanical benefit of scraping the teeth clean, making it great for maintaining your cat's dental health. On the other hand, wet food is typically more palatable and given its higher moisture content, it helps support bladder and kidney health, which is particularly important in felines due to their low thirst drive. Wet food also helps with weight management for indoor cats, as it contains fewer calories than dry food. Generally for indoor cats, we recommend a 50/50 mix of dry and wet foods to ensure your feline friend receives the benefit of both types of diets.

How much do I feed my indoor cat?

As obesity is common in indoor cats, it's important not to overfeed and to follow the recommended feeding guidelines on the back of the bag/can of food. Also make sure to accurately measure the amount of food you are feeding per day (using kitchen scales is a great way to do this). Using an automatic feeder or puzzle toy can also help to slow down feeling to help with weight control, as well as provide mental enrichment which is so important for indoor cats.

Does my indoor cat really need a specialised diet?

While not a strict requirement for every cat, an indoor diet is highly beneficial for most. The biggest health challenge for indoor cats is often obesity and the health problems that follow, such as arthritis and diabetes.

An indoor formula is a proactive tool to help manage their calorie intake and body condition. If your cat is already at a perfect weight, is very active (with lots of indoor play), and doesn't suffer from hairballs, a high-quality standard adult food may be fine. However, for the typical indoor cat, a specialised diet is an excellent choice.

My cat is already overweight. Will an indoor food help them lose weight?

This is an important distinction. An indoor formula is designed for weight maintenance and the prevention of weight gain. It is not specifically a "weight loss" diet.

If your cat is already overweight, they may need a diet that is even more restricted in calories and fat. These are often labelled as 'Light' or 'Weight Control' formulas. For significant weight issues, a veterinary prescription diet is often the most effective and safest solution.

It is always best to speak with your vet to get a proper assessment of your cat's body condition and create a dedicated weight loss plan.
