Low Protein Cat Food Buyers Guide
Usually, when you’re searching for the ideal food for your cat, protein will be one of the first ingredients you prioritize.
After all, cats are carnivores that rely heavily on a high intake of protein to keep them as fit and healthy as possible.
However, there are cases where protein might cause a number of problems for your kitty if they get too much of the wrong type.
If your cat has a health condition like kidney or liver disease, research indicates that a lower protein diet might be a better choice.
Your vet might recommend switching to more highly digestible sources of protein, as well as cutting out certain ingredients like sodium and phosphorous.
Protein produces something called “nitrogenous waste”, which can place an additional burden on your cat’s kidneys, as well as other essential organs.
For cats, protein is a life-giving substance necessary for a healthy diet. You won’t be able to cut this product out of your cat’s food entirely, but you can adjust their intake with a limited-ingredient meal option.
As always, you’ll need to talk to your vet to ensure you’re choosing the right diet options for your kitty. Don’t switch to a low-protein diet without a vet recommendation.
Picking a Low Protein Cat Food Diet
Because low-protein diets for cats are often recommended on a prescription basis, there’s a good chance your vet will give you advice on what kind of food you should be buying for your furry friend.
However, if you’re free to do your research yourself, there are a few things to consider aside from a low protein content when making the right choice.
First, keep in mind that low-protein cat food isn’t the same as giving your cat no protein at all.
Your kitty will still need protein to survive, but you’ll need to focus on choosing proteins that are high-quality, easy to digest, and highly “bioavailable”.
Other factors to look at include:
If you’re not sure about any of the cat food available for your furry friend, consider speaking to your vet for their recommendations.
Risks of a Low Protein Cat Diet
Low protein diets for cats generally aren't the best option for a standard cat.
In general, high amounts of protein are better suited to your feline friend, as they help with things like weight management, reduced risk of obesity, and energy production.
Switching to a low-protein cat food without your vet’s recommendation could lead to:
Why Is Protein So Important For Cats?
Cats can’t live without protein. As obligate carnivores, cats can live their entire lives eating nothing but animals and animal by-products without suffering from any nutritional deficiencies.
In fact, cats require a lot more protein than other animals, like dogs, who are omnivores.
Protein is a life-giving substance for your feline friend, and it gives it the strength and energy they need to function every day.
Protein is vital to every process in your cat’s body.
While the exact dietary requirements of your cat may vary when compared to other felines, most cats need at least 2.36 grams of protein per pound of body weight on a daily basis.
Studies show anything less than this amount could make it difficult for your cat to maintain muscle mass.

Cats With Kidney Disease
The most common reason to switch a cat onto a low-protein diet is that it’s suffering from kidney disease.
Currently, research into a low-protein diet’s benefits for cats with kidney disease is still ongoing.
However, we do know the kidneys play a crucial role in processing the nitrogenous wastes created by protein digestion.
Because cats with kidney disease aren’t able to process this waste as effectively, it can build up in their bloodstream and cause significant problems.
A low-protein food can help to reduce this issue, but it can also lead to other problems in its own right.
For instance, a cat with kidney disease still needs protein as much as other cats.
While they might feel a little better than they did on their previous diet with low-protein food, you might find your cats struggle to get the right level of nutrition and end up losing weight.
Most vets say instead of focusing on reducing protein, pet parents should instead focus on changing the source of the protein to ensure it’s as digestible as possible.
Cats With Liver Disease
Cats with liver disease may also be recommended a low-protein diet. The liver also plays a role in removing some of the toxic waste from protein digestion.
This means a diet high in low-quality protein could place additional strain on an already problematic liver.
Switching to a low-protein diet focused heavily on high-quality sources of protein can make it easier for your cat to manage their food.
Your vet may recommend a low-protein diet for your cat as a way of reducing the amount of ammonia the liver allows to remain in the body.
Recent research, however, does suggest it’s more valuable to provide your cat with the right kind of high-quality protein than it is to reduce their intake entirely.
Older Cats
In some circumstances, it may also be recommended that your cat reduce its protein intake with age.
This is generally because senior cats are more likely to suffer from kidney disease. This means their kidneys need a little more support.
However, the reality is that older cats generally need more protein and calories than they did in their earlier years.
With this in mind, it’s not a good idea to simply switch your cat to a low-protein diet based on their age alone.
Speak to your vet if you’re not sure about the right diet strategy and especially if your cat's appetite drops off.
