Nonetheless, outdoor cats need feeding and care, albeit not as much as their indoor counterparts. Unsurprisingly, they are still incredibly picky about the kind of food they eat.
Being obligate carnivores, cats must eat primarily meat. Their digestive systems are not designed to digest plants or carbohydrates, and as such, they can get sick when they eat too many.
Additionally, cats do not make their own taurine like canines do. Taurine is an amino acid that supports nerve, brain, and heart functions. Unfortunately, taurine can only be derived from animal products.
Regrettably, quality cat food is not easy to come by. It is not unheard of for manufacturers to cut corners by utilizing non-essential ingredients to save money. Fortunately, we have done the legwork for you and compared different outdoor and feral cat foods. The following are reviews of the best cat foods for outdoor cats.

The 6 Best Cat Foods for Outdoor Cats
1. Smalls Fresh Cat Food Subscription — Best Overall
Several wet cat foods are highly recommended, but feeding your outdoor cat a can of wet food can have its downfalls. Not only is wet food messy, but it will also spoil quickly, and the scent attracts other animals. Our overall best cat food for outdoor cats goes to Smalls Fresh Cat Food. This healthy, fresh, human-grade alternative to the typical dry kibble allows you to skip out on the wet mess.
Each Smalls recipe is made from sustainably sourced ingredients in the United States or Canada. The food is derived from USDA-certified ingredients, rich in protein, and free from grains, fillers, and any artificial additives.
This option may be a bit more on the expensive side but is a wonderful, healthy outdoor cat food that you won’t have to worry about spoiling too quickly!
- Better shelf-life than dehydrated foods
- Free from fillers, grains, artificial additives, and by-products
- Made from USDA-certified ingredients approved for human consumption
- Retains more nutrients than dehydrated food

2. Purina Beyond Grain Free Cat Food — Budget Buy
This cat food for outdoor cats by Purina Beyond is a gluten-free product that ensures that outdoor cats meet all their nutritional requirements. It consists of a nourishing all-natural formula with recognizable ingredients so you can be sure about what you are feeding the cat.
Chief among those ingredients is a combo of protein-rich hake fish, chicken meal, and eggs that provides your cat with adequate protein. This formula is also enriched with vitamins A, B-12, D-3, and E, as well as biotin, folic acid, and zinc to ensure the cat gets the balanced and complete meal they need for a full and healthy life.
The formula also contains taurine, which helps boost heart, brain, and nerve function and improves eyesight. However, it does not contain carbohydrates from corn or soy, which some manufacturers are notorious for adding to their products. It also does not have any artificial flavors, colors, or preservatives.
Nonetheless, Purina Beyond contains starchy vegetables, which can cause bloating. With time, however, the kitty can learn to tolerate it, which is why the manufacturer suggests starting small and gradually increasing the servings as the animal becomes accustomed to the food. Despite being a superior product on the market for quality, it’s also one of the best cat foods for outdoor cats for the money.
- Gluten-free
- High-quality protein from hake fish and chicken meal
- Does not contain empty calories in the form of wheat, soy, or corn
- No added flavors, colors, or preservatives

- Contains starchy ingredients that might cause bloating
3. Blue Buffalo Wilderness High Protein Grain Free Cat Food
Wilderness by Blue Buffalo is a tasty, grain-free, and protein-full meal that’s “cold-formed.” Cold formation is a process that limits the amount of heat utilized during the preparation of ingredients to prevent them from losing their nutritional value.
Blue Wilderness contains a minimum of 38% protein per serving, which is more than enough to meet your feline’s nutritional needs. The manufacturer also indicates all the sources of the other ingredients in Blue Wilderness to ensure that you have peace of mind. In addition to being grain-free, it does not contain soy, wheat, or any artificial colors or flavors. This ensures that your cat does not have any adverse reactions.
If you want to give your outdoor cat a hearty meal, look no further than Blue Wilderness.

4. Hill’s Science Diet Dry Cat Food
Hill’s Science Diet is one of the most reputable companies in the pet supplies industry and for good reason. Their products never disappoint when it comes to quality. This outdoor cat food is not any different. First, it comes in a 13-pound bag to ensure more than enough for your kitty to enjoy.
The formula is specifically made to assist elderly cats with their digestive processes, and it’s enriched with prebiotic fibers that encourage healthy gut function. The easily digestible kibbles are also grain-free, thus ensuring that your furry friend’s health is not put at risk. Plant-based ingredients can be harmful to your cat.
The protein in Hill’s food comes from chicken. Recently, however, Hill’s Science Diet changed the product’s packaging, as well as the size and taste of the kibbles. It seems that some cats are having difficulty adjusting to the new product, which means that you might want to purchase a smaller bag to see how well your kitty will love the repackaged version.
Fortunately, the manufacturer provides detailed instructions on how to transition your cat to this food to prevent issues such as loss of appetite, constipation, or diarrhea.
When it comes to quality, Hill’s Science Diet is one of the best options. However, it is pretty pricey.
- Chicken protein
- Contains omega-3 and omega-6 fatty acids for a healthier immune system, stronger vision, and a more luscious coat
- Enriched with prebiotic fibers for better gut health
- Requires adjusting to the new product
- Pricey
5. Instinct Original Real Chicken Natural Dry Cat Food
This dry cat food by Instinct Original is a delicious, nutritious formula consisting of 81% ingredients from real animals and 19% healthy fruits and vegetables. The meat utilized in the formula is derived from free-range chicken.
Since it has high protein levels, Instinct Original is ideal for active felines, such as your outdoor kitty. It is also enriched with other essential ingredients, such as probiotics, antioxidants, and natural omegas.
Probiotics help promote gut health, while antioxidants eliminate dangerous free radicals in the body that weaken the immune system. On the other hand, natural omegas help promote healthier skin and coats.
Instinct Original does not contain filler ingredients like grains, potatoes, corn, wheat, or soy; it also does not contain artificial colors, flavors, or preservatives.
Additionally, every piece of kibble in Instinct Original’s Cat Food comes covered in freeze-dried material to maintain its nutritional value and enhance its taste. However, the issue with Instinct Original is that it contains peas, which have a slight chance of causing bladder and kidney stones in some felines.

- Enriched with probiotics, antioxidants, and natural omegas

This cat food contains complex carbohydrates that provide additional energy. Flaxseeds are a natural source of omega-6 fatty acids that promote healthier skin and fur. Wellness Complete’s Dry Cat Food is enriched with antioxidants, minerals, vitamins, and taurine to promote better overall health.
You will also find prebiotics, probiotics, and healthy fibers in this product to ensure that your cat digests their food properly, and it prevents hairballs from being an issue.

Buyer’s Guide: How to Find the Best Cat Food for Outdoor Cats
Cat food for outdoor cats differs in price, quality, and nutritional value. The following are the most important things to consider when buying food for your outdoor cat.
Protein Type and Content
Cats are obligate carnivores, which means that they need animal-based protein for survival. An outdoor cat needs at least 30% protein in their meal for optimal health. Additionally, felines of different ages require different amounts of protein.
For instance, kittens typically need higher amounts, as they still build muscles and other tissues. Healthy adult cats can do with average amounts, as they only need to maintain their tissues. Elderly felines, on the other hand, require above-average amounts of protein to combat the effects of aging, such as tissue degeneration.
Ingredients
Unlike dogs, cats do not do well with carbohydrates, though they can tolerate low amounts, even eating grass outdoors. Nonetheless, most of the ingredients in cat food should consist of animal-based products; ideally, the first five ingredients on the label. However, this can make the chow pricey, so some manufacturers include vegetables in the first five ingredients.
If you can afford it, go for the food in which the first five ingredients are meat-based. Never buy outdoor cat food with fewer than three meat-based products in its first five ingredients.
The Label
The label contains all the information you need to help you determine whether the food is appropriate for your kitty. For starters, it lets you know whom the diet is designed for. Some cat foods are meant for kittens and some for adult cats, while others are for sick kitties. As such, when it comes to outdoor cats, ensure that the label states that the food is intended for active felines.
The label also indicates the bag’s weight. Depending on the amount of food your furball typically consumes, you should be able to calculate the number of servings a bag can give you, thus allowing you to determine whether it is a cost-effective option.
