Nutrition experts agree that plant-based diets are extremely healthy… for humans any way. There is some concern about meeting your needs for specific nutrients including protein, but it is perfectly possible to create a balanced plant-based diet. Plant foods like peas, lentils, and legumes offer plenty of protein as well as other essential nutrients.
Unfortunately, these foods are not quite as healthy for your cat. If you know anything at all about feline nutrition, you probably know that protein is important. You may also know that your cat is a carnivore and needs meat rather than plants. Ingredients like peas and lentils in cat food often add extra protein, but not in a form your cat can efficiently process. Pet food manufacturers, particularly those selling grain-free diets, don’t tell you that on the label.
In this article, we’ll talk about the role of peas, lentils, legumes, and potatoes in cat food as well as the potential problems they can cause. We’ll also discuss the things you should be looking for in a healthy cat food and provide you with some of our top recommendations for a pea free cat food. Read on!
- Loaded with protein-rich chicken
- Features flavorful smooth texture
- Has high moisture content to promote daily hydration.
- No Preservatives
- No Growth Hormones
What Are the Problems with Grain-Free Cat Food?
When you head to the pet store to shop for cat food, what do you look for? You probably spend a minute or two walking down the aisle, scanning the names on the packages. Words like “chicken,” “real meat,” and “natural” probably catch your eye. But what about the term “grain free?”
The fact that a product is free from something may lead you to believe that it’s better for it. But are grains actually a problem in cat food? Not necessarily
The popularity of grain-free pet foods stems from a rising fear of grain allergies in pets. Pet food manufacturers would have you believe these allergies are more common than they are. In reality, the most common cat food allergens are proteins like chicken, beef, and fish as well as dairy products, eggs, and artificial additives. Whole grains can actually be very nutritious for cats, as they are for humans, but still shouldn’t outweigh the animal protein in your cat’s food.
But what’s the problem with grain-free cat food? One of the biggest issues with grain-free diets is that the carbohydrates used to replace grains are often high in protein and may contain certain harmful ingredients. More protein? What’s the problem?
The problem is that cats are obligate carnivores which means they are biologically evolved to digest animal products, not plants. They have a short digestive tract and lack the digest enzymes needed to digest plant protein, so plant proteins like peas, lentils, and legumes are not particularly beneficial for your cat in terms of nutrition. They may also contain harmful or even toxic ingredients like phytic acid which could impede your cat’s ability to absorb nutrients.
Grain-free diets aren’t all bad, but they are not inherently healthier for your cat than a diet that includes whole grains. The only time you really need to feed your cat grain-free is if he has a diagnosed allergy to grains and your veterinarian recommends it.
What You Need to Know About Peas, Lentils, Legumes, and Potatoes in Cat Food
We’ve already mentioned the fact that peas, lentils, legumes, and potatoes are often used in grain-free foods, but now we want to delve deeper into the problems they can cause.
The biggest problem with ingredients like these is that they can increase the total protein content of the recipe. Even if the first ingredient is fresh meat, there’s no guarantee that the recipe contains more animal than plant protein. Fresh meats contain up to 70% moisture which will be cooked out during processing. Plant proteins, on the other hand, are often already cooked or contain much less water, so they could end up weighing more than the cooked meat in the end. This could mislead consumers into thinking the product is higher in animal protein than it really is.
Aside from increasing the perceived protein content of the cat food, what are the other issues with ingredients like peas in cat food?
First and foremost, you should know that the peas used in pet foods are generally not the fresh green peas you find in the supermarket, they are dried peas. Peas and lentils are legumes, so the issues that apply to them also apply to legumes in general. The problem with these ingredients is that they contain lectins, sugar-binding proteins that plants use as natural defenses against predators. They act as natural insecticides and fungicides.
These lectins are designed to bind or stick to sugars, but they also end up sticking to the lining of the small intestine. This can damage the villi lining the intestine which are responsible for absorbing nutrients. Lectins have also been shown to harm the microflora in the gut that support digestion.
Another problem with legumes in cat food, specifically things like chickpeas, alfalfa, and soy products, is that they contain phytoestrogens. Phytoestrogens mimic or interfere with the estrogen produced in the body by binding themselves to estrogen receptors. This has been linked to issues like delayed puberty, infertility, autoimmune disease, developmental issues, and neurodegenerative disease. Lentils are much lower in phytoestrogen content than soy products, but they still contain phytates which bind to certain minerals like zinc, iron, and calcium which can leech them out of your cat’s body.
So, what’s the problem with potatoes?
One of the issues with potatoes is that much of the potatoes in cat food are in the form of protein. As you remember, plant proteins are less biologically valuable than animal proteins for cats and much cheaper as well. Potato starch is another common ingredient that provides little nutritional value, acting primarily as a binding agent. There is some concern that the glycemic index of potatoes is a little high, meaning that it has a more significant impact on blood sugar and insulin levels than other foods, but these concerns are based on the impact on humans – it may not be quite the same for pets.
The long and short of it is that ingredients like legumes in cat food are less than ideal. They may not cause your pet any immediate harm, especially in small amounts, but they don’t support his optimal nutrition and may lead to problems with digestion and nutrient absorption over time.
What Should You Look for in a Healthy Cat Food?
We’ve spent quite some time talking about ingredients you should avoid in your cat’s food, but what do you need to be looking for? It’s important to remember that your cat is an obligate carnivore, so he has a biological requirement for meat in his diet. More specifically, 26% of his diet for adult cats and 30% for kittens. These are absolute minimums, however, so more protein is usually better. You also want to make sure the recipe is labeled complete and balanced according to AAFCO food nutrient profiles.
Here’s what to look for in cat food:
- Rich in quality animal protein. The majority of your cat’s diet should come from animal sources, including his protein. Named sources of poultry, meat, and fish are ideal, though named by-products like chicken by-products are not necessarily bad. Just avoid generic proteins like meat by-products or poultry meal because you won’t be able to judge the quality easily.
- Moderate healthy fat content. Fat provides your cat with a concentrated source of energy as well as essential fatty acids – it should come from animal ingredients like chicken fat and salmon oil, though plant oils like sunflower oil can provide omega-6s to balance out the omega-3s.
- Low in digestible carbohydrates. Your cat has no biological need for carbohydrates in his diet, so the carb content of your cat’s diet should be low and limited to highly digestible options.
- Fresh fruits and vegetables. Peas and potatoes are not the best vegetables for your cat, but things like leafy greens are. Fresh low-starch vegetables and fruits provide natural sources for key nutrients in a more biologically valuable form than synthetic supplements.
- No corn, wheat, or soy ingredients. In addition to avoiding peas, lentils, legumes, and potatoes in cat food, you should also avoid corn, wheat, and soy ingredients. They offer little to no nutritional value and come with similar issues.

Frequently Asked Questions
Should I feed my cat food without grains?
Generally speaking, there is no nutritional need to feed your cat grain-free cat food. The exception is for cats who have a diagnosed grain allergy. Even then, you need to be careful about switching to a grain-free cat food without paying attention to the ingredients. High-protein plant foods like legumes, lentils, and peas contain potentially harmful ingredients, so you should avoid cat foods that contain them in high quantities. Fresh vegetables are preferable.
Are potatoes in cat food always bad?
According to Solid Gold Pet Food, one of our preferred brands, potatoes can be both good and bad in pet foods. They are grain-free carbohydrate rich in vitamin C, potassium, and B vitamins in addition to being fairly low in calories. They are also easily digested and generally well tolerated. The problem is that they are high in starch and may have a higher glycemic index rating than fresh vegetables.
Why should I look for a cat food without corn, wheat, or soy?
There are plenty of cat food ingredients you want to look for but just as many you want to avoid. Low-quality grains and fillers are common in cheap cat foods, typically used to add bulk to the product or to increase the protein content. The problem is that cats have trouble digesting these ingredients, so they don’t actually provide much value. This is true for corn, wheat, and soy ingredients.
How much should I feed my cat?
The amount you feed your cat depends on his age, weight, and activity level. Kittens and very active cats have higher needs for calories than adult and senior cats, so keep that in mind. Choose a cat food appropriate for your cat’s life stage and follow the feeding instructions on the package according to your cat’s age and weight. You may want to err on the side of underfeeding for adult and senior cats to prevent obesity, but increase your cat’s daily ration if he becomes sluggish or starts to lose weight.
How often should I feed my cat?
Most cats do well with two meals per day, one in the morning and one in the evening. If you have a kitten, more frequent meals may be recommended to support growth and development. If you’re not sure how often you should be feeding your cat, you can ask your vet for recommendations.
We’ve covered a very complex subject in this article in the best way possible to give you an overview without confusing you too much. The key takeaway here is that you can’t necessarily trust pet food manufacturers to do what’s best for your cat – that’s your job.

We understand that choosing a cat food can be tough, so we’ve done our best to give you the information you need to make a smart decision. If you’re still confused, don’t worry – you can simply try one of the recipes we’ve recommended above!
