7 Best Indoor Cat Dry Food Products

Indoor Cat Dry Food

In this article we first look at the nutritional requirements of indoor cats compared to outdoor cats, followed by reviewing the 6 Best Indoor Cat Dry Food Products that we can find in the marketplace.

Wild Cats vs Indoor Cats

Cats in the wild are always on the prowl looking for food, defending their territories, keeping cool/warm and evading threats. They are highly active with elevated metabolism. A sedentary lifestyle is generally the norm for many indoor moggies.

These statements are generalizations, as all cats are different, whether they are indoor or outdoor cats. For example, there will be indoor cats with a high metabolism. After browsing this article, you will know what is best for your cat with regards to nutrition, as only you know your cat!

Nutritional Requirements of Cats

top dry cat foods of 2021All cats, whether indoor or outdoor, have the same basic nutritional requirements. Cats are carnivores and thrive on a quality meat protein diet that includes a balance of fats, carbohydrates, vitamins and minerals.

A cat’s diet varies depending on her age, size, current health and whether she is a mother with lactating kittens. Therefore, taking these factors into consideration will help with deciding on the best food for her.

Indoor Cat Dietary Consideration

An indoor feline who is less active than her outdoor cousin, may be more prone to gaining weight. A diet with less calories will benefit her. Set feeding times with portion control, rather than always having indoor cat dry food on offer, help reduce calorie intake.

Developing hair balls tends to be more common with indoor cats, so a diet higher in fiber reduces this problem.

Outdoor cats will likely be actively catching small animals, which they will be snacking on. They may not be as hungry as indoor cats at mealtimes. The prey they catch and eat will be high in protein and nutrition.

Indoor cats will be totally reliant on the cat food cat owners present to them, making it important to select a quality balanced indoor cat food formula.

The Difference Between Indoor Cat Dry Food and Regular Cat Food

  • Lower protein
  • Higher fiber
  • Lower calories
  • Tends to have less grain fillers

The Downside to Indoor Cat Dry Food

In order to reduce calories, real meat ingredients are switched out for high fiber vegetables such as sweet potatoes, peas and corn. This is perfect for sedentary humans who want to lose a few pounds, but not for the obligate carnivore that a cat is.

Cats with allergies to gluten may react to such a diet. Indoor cat dry food may contain other additives such as cellulose, salt, meat byproducts and flours.

The Upside to Indoor Cat Dry Food

Less fillers are always good. You don’t want to just fill your cat, you want to nourish your cat.

Being prone to hairballs, the high fiber will help push the hair through her system before it can form into a hairball. Reduced calories will keep excess weight off.

Supplementing an Indoor Cats Diet

Outdoor cats are eating small animals, topping up with their nutrition. They eat bones, organs, and all. They will be digesting minerals, vitamins and macro nutrients.

You can make up for possible deficiencies in indoor cat food by supplementing your cat’s diet. A bit of lean meat (fully cooked, or raw) every now and then, will give her a protein boost.

Talk to your veterinarian about vitamin supplements that may be beneficial to your cat.

Hill's Science Diet Kitten Healthy Cuisine Roasted Chicken & Rice Medley Canned Cat Food, 2.8-oz, case of 24 + Hill's Science Diet Indoor Kitten Dry

We have chosen the Hill’s brand for a dry kitten kibble because the company involves animal nutritionists and veterinarians in the formulation of their products. We like that the indoor kitten kibble has a chicken meat protein as it’s main ingredient as opposed to fish ingredients (to much fish for kittens is not a good idea).

The kibble is specifically formulated for growth, has small kibble size for easy eating and is well supplemented offering a balanced diet for kittens.

Iams Proactive Health Adult Dry Cat Food Chicken & Salmon 


Iams ProActive Health Healthy Adult Original with Chicken Dry Cat Food, 3.5-lb bag
