The 9 Best High Protein Cat Foods
1. Blue Buffalo Wilderness High Protein Dry Cat Food — Best Overall
We recommend Blue Buffalo Wilderness High Protein Dry Cat Food as the best overall choice in this category. The first ingredient of this cat food is deboned chicken, a sure sign that this is a high-quality product. The formula is inspired by the diet of the Lynx and is designed to provide your domestic cat with the optimum blend of protein, complex carbohydrates, and fat to keep them in the best of health.
It also includes Blue Buffalo LifeSource Bits. These include a carefully blended combination of vitamins, minerals, and antioxidants that are designed to support your cat’s immune system and overall health. This food is designed to help support your cat to develop and maintain the best of health.
All in all, we think this is the best high protein cat food of 2021.
2. DIAMOND NATURALS High Protein Dry Cat Food — Best Value
If you’re looking for the best high protein cat food for the money, then the Diamond Naturals High Protein Dry Cat food is our suggestion. This nutrient-rich dry cat food is designed for active cats and will help them to build strong, lean muscle mass. As well as a high percentage of protein, this food also includes antioxidants and fatty acids.
We love that Diamond Naturals doesn’t contain any artificial preservatives, colors, or flavors. It’s also free from corn, wheat, and fillers. While the Diamond Naturals High Protein Dry Cat Food is excellent value for money, it misses out on our top spot because the first ingredient is chicken meal, rather than deboned chicken.
3. ORIJEN High-Protein Cat Food — Premium Choice
Our premium choice is manufactured by ORIJEN. This includes a great blend of biologically appropriate ingredients for your cat to enjoy, including wild-caught fish, cage-free eggs, and free-run turkey and chicken. ORIJEN also uses a mixture of “whole prey” meats, namely organs, cartilage, and bone. This is designed to mimic the natural diet of wild cats.
As well as high protein content, this food contains a blend of fruit, vegetables, and botanicals to provide everything that your cat needs to thrive. While ORIJEN is a wonderful premium choice, if you have multiple cats, then the cost of using this food will soon add up quickly! This cost consideration is the only thing that’s keeping it out of the top two spots on this list.
4. IAMS Proactive Health High Protein Cat Food
The Iams Proactive Health High Protein Cat Food is also a great choice, with 84% of the protein content within this dry cat food being sourced from chicken and salmon. Suitable for both indoor and outdoor cats of all life stages, this dry cat food also contains a tailored blend of fiber, carefully selected to help your cat’s digestive system stay healthy and strong.
It also contains a blend of essential minerals, including calcium for your cat’s teeth and bones. The premium recipe contains plenty of high-quality ingredients, but what it doesn’t include are any synthetic dyes, wheat, or artificial preservatives. And that’s always good news!
5. Purina ONE High Protein Adult Dry and Wet Cat Food
The Purina ONE High Protein Adult Dry and Wet Cat Food is a great choice if your cat loves to eat fish! With real ocean whitefish as the first ingredient, this food will provide plenty of great taste thanks to its blend of crunchy bites and tender morsels of meat. This food contains zero fillers, meaning you can be confident that every bite your cat takes is full of natural goodness.
What’s more, Purina ONE is veterinarian recommended. You can choose between a range of wet and dry food, knowing that it’s all designed to help your cat develop strong muscles and energy. Of course, these blends all contain the vitamins and minerals your kitty needs, in addition to the high protein content.
6. CRAVE High Protein Dry Cat Food
With chicken as the first ingredient, CRAVE High Protein Dry Cat Food contains 40% protein to provide indoor cats with all the nutrients they require in order to lead healthy lives. While it does also contain chicken meal, it’s thankfully free from chicken by-products. You also won’t see soy protein, corn, or wheat on the ingredients list.
Even better, it’s free from artificial preservatives, colors, and flavors. The inspiration behind this formulation is providing your cat with a diet as similar as possible to their ancestral diet, while using natural sources of quality carbohydrates to support their digestive and immune systems. It’s also available in a kitten version in case you want to start your cat on this from the beginning.
7. Solid Gold High Protein Holistic Dry Cat Food
The Solid Gold High Protein Holistic Cat Food is a great choice if you’re looking for a formulation that can be used for all life stages from kitten to senior.

8. Taste of the Wild High Protein Premium Dry Cat Food
If you’re looking for a high protein cat food with a slightly different flavor profile for your fussy cat, the Taste of the Wild High Protein Premium Dry Cat Food might just tick all their boxes. This formula uses a blend of roasted venison and smoked salmon to provide a taste your cat will love.
It’s worth bearing in mind, though, that the first ingredient listed is chicken meal, so that’s where the majority of the protein percentage will be coming from. It does have a high protein content, coming in at 42%, which is higher than most other brands we reviewed.
9. Natural Balance L.I.D. High Protein Dry Cat Food
L.I.D. stands for Limited Ingredient Diet, which makes the Natural Balance L.I.D. High Protein Dry Cat Food an excellent choice for cats with allergies or food sensitivities. This dry cat food makes it easier to manage this sort of issue by using a simpler formula with fewer ingredients than many other brands of high protein cat food.
The Natural Balance high protein cat food isn’t recommended for kittens, though, so you’d be better off choosing a different brand if you’re looking to start your kitten or young cat onto a high protein diet.
Buyer’s Guide: How to Select the Best High Protein Cat Food
High Protein cat food is an excellent choice for many furry felines, but it’s important to do research before going ahead and switching your cat to this diet. Not all high protein cat foods are created equally, and some are a better buy than others. So, what should you be considering?
Why is a high protein diet good for cats?
Cats are obligate carnivores, which means that as a species, they’re designed to eat a solely meat-based diet. In fact, a cat’s requirement for protein in their diet is estimated to be up to three times greater than omnivorous species such as humans and dogs.
Read the ingredients
While a packet of high protein cat food might look like the best choice, the only way to know is to take a closer look at the ingredients list.
Good-quality high protein cat food will include real meat as their first ingredient, so make sure to check this. Mid-range high protein cat foods will usually use a meat meal as the first ingredient. While the percentage of protein will still be high, the quality of the meat meal will not be as good as real meat.
How much protein is high protein?
While you’re checking the ingredients list on the back of a new packet of cat food, be sure to look at the nutritional breakdown of the food as well. The first thing to check will be the percentage of protein.
According to The Association of American Feed Control Officials, also known as the AAFCO, any cat food should contain at least a minimum of 26% protein to meet the basic requirements of a cat’s maintenance diet. For younger cats in the growth phase, 30% protein is recommended.
A high protein cat food is defined as one which contains 30% or more protein. The products on this list range from Purina ONE, with the lowest percentage of 35%, to Taste of the Wild and Solid Gold, which tie for the highest percentage at 42%. The majority has a protein content of 40%.
All cat food will have the nutritional breakdown on the back of the packet. When buying from an online retailer, such as Amazon, you can easily find this information either within the product images or the description.
Which nutrients do cats need?
As well as protein, there’s a range of nutrients that your cat needs in order to stay healthy. Many of these are sourced from within the protein percentage of your cat’s diet.
Protein contains amino acids, including taurine. Taurine is one of the most important nutrients in a cat’s diet. As cats can’t synthesize, or make, this nutrient themselves, they must gain 100% of their daily requirements from their food
Next up, omega-6 fatty acids are needed to help your cat’s coat and skin stay strong and healthy.
Vitamins are also important! Cats need vitamins A, B1, and D3.
Almost all cat food will list the guaranteed minimum percentages of taurine and omega-6 fatty acids that their blend contains. Some will also list omega-3 fatty acids and the range of vitamins and minerals that they contain.
Check with your veterinarian
Before making any changes to your cat’s diet, we recommend speaking to your veterinarian first. Some cats can suffer from kidney problems, with this being more common in older cats.
If your cat has kidney issues, then feeding them a higher protein food can potentially cause more problems, so you’ll definitely want to check this with your veterinarian first.
How to change cat food
Once you’ve decided on and purchased your new cat food, it’s important to take time to introduce it to your cat slowly to reduce the risk of them developing an upset stomach.
Most manufacturers will include recommended quantities for transitioning your cat to their new diet. As an example, over six days, you can add 25% of the new food to your cat’s existing feed for the first two days. For days three and four, mix the foods with a 50/50 split. On days five and six, you’ll be using 75% new food and 25% old food. On day seven, you can use 100% new food, and your transition is complete!
We selected the Blue Buffalo Wilderness High Protein Dry Cat Food as the best overall choice. Inspired by the diet of the Lynx, your domestic kitty will love the combination of tasty flavors and 40% protein that this cat food offers.
We highly recommend DIAMOND NATURALS High Protein Dry Cat Food as the high protein cat food that offers the best value. It combines nutrient-rich flavor and 40% protein; though its first ingredient is chicken meal, it does contain real chicken too!
We’re confident that there’s a high protein cat food that will suit your cat!
Of course, the real test will be allowing your cat to enjoy their new food. We’re sure they’ll thank you!
