Best High Protein Cat Food Buying Guide & FAQ
Benefits of Feeding Your Cat High Protein Food
There are numerous benefits to feeding your pet a high protein diet as it closely resembles their natural diet in the wild. One of the main reasons why cats are such carnivores is that they don’t have the right salivary enzymes to break down the starch found in a carbohydrate-based diet. This means that higher carbs in your cat’s diet can lead to digestive and other health issues.
Your cat also needs a natural balance of amino acids, which are found in animal protein. Amino acids are essential for a host of feline body functions, including growth, repair, digestion and energy. A high protein cat food diet can also stave off certain medical conditions, including diabetes and will help to main your cat’s healthy body weight. Head over to our review of cat food for weight loss for more alternatives.
Potential Downsides of High Protein Diet For Cats
While a high protein diet can be the best option for your healthy cat, there are some potential negatives to feeding them too much protein. A high protein diet can actually be harmful to some cats, especially more senior felines. Older cats can actually be at risk of developing kidney disease if fed too much protein. Kidneys are responsible for filtering out excess protein and if the kidney function of your senior cat is below par, a high protein diet can cause issues for their health.
Cats at any age with certain health conditions, including kidney disease, diabetes or obesity, will also need to have the amount of protein in their diet monitored. If you're in any doubt whether you should feed your cats a high protein cat food, speak to your veterinarian.

Dry or wet: Depending on your cat’s preference as well as health, you'll need to choose between dry or wet food.

Meanwhile dry cat foods are easier to free feed your kit and are generally cheaper.
Protein content: The protein level is essential for your cat to get the benefits, so always check the nutritional analysis on the packaging. Your cat also needs the protein to be as digestible as possible, so look for whole animal protein such as chicken as the first ingredient, rather than rendered meat, which is listed as a by-product.
Quality ingredients: As with all pet food, look for the highest quality, natural ingredients. So that means avoiding artificial colors, flavors or preservatives as well as fillers.
Essential nutrients: Your cat’s diet needs to provide the essential nutrients they need for optimum health. As well as a natural balance of vitamins and minerals, look for amino acids such as taurine, which your cat needs for their vision, digestion, heart and immune system. Check out our guide on vitamins for cats for more info.
