What is better than IAMS

IAMS vs PURINA Cat Food: Our 2024 In-Depth Comparison

Picking the perfect food for your feline seems like a pretty easy task. At least until you walk into the local pet store and see how many options there are. Even a walk down the pet aisle at the nearest grocery store will reveal that there are a plethora of choices to pick from, and they all seem to offer some awesome benefits. How much of it is real, and how much is advertising? How are you supposed to know?

We were wondering the same things, so we set out to get some answers. After a lot of searching, we found that two of the most popular cat food brands that consumers have a hard time picking between are IAMS and Purina. So, we decided to put both brands to the test and see who would come out on top.

A Sneak Peek at the Winner: IAMS

It was honestly a very close call, with both brands bringing forth some impressive offerings. In the end, IAMS won us over with cost-effective products that use more animal-based ingredients. They have a versatile selection of cat foods to choose from, including some of our favorites like the IAMS Proactive Health Adult Indoor Weight and Hairball Control blend or the IAMS Proactive High Protein Adult Cat Food.

But dont let that make you think that was an easy decision. Purina brought a lot to the table as well, with a more versatile selection of products that include some specialty foods that bring about specific results like reducing the allergens your cat is releasing or achieving and maintaining urinary tract health.

This decision could have gone either way, so youll want to take in all this information and make a decision of your own to see if you agree with our consensus.

About IAMS

IAMS is an international company thats sold in more than 75 countries. They make a wide variety of pet food products for dogs and cats. Their feline foods fit every furball, including kittens, seniors, healthy cats, cats with sensitive stomachs, and more. They offer recipes to maintain a healthy weight, reduce hairballs, and improve your cats coat and skin.

Humble Beginnings

Iams was first started by Paul Iams. Paul had sold dog food during the Great Depression, and this experience proved invaluable since it taught him that people will find a way to feed their dogs, no matter how destitute their position. Seeing this inspired Paul to start the IAMS pet food company, founded in 1946. In 1950, their first product was introduced, IAMS 999.

The Mars Acquisition

Since those early beginnings, IAMS has gone through several major transformations. Eventually, this culminated in the 2014 purchase of IAMS by Mars Inc., which is the largest pet food brand in the world today. However, that purchase wasnt complete since the European branch of IAMS was sold to Spectrum Brands, being purchased again in 2020 by United Petfood.

From Pet Stores to Big Box Stores

There was a time when IAMS food was only found in specialty pet stores and veterinarians offices. But today, youll find IAMS in many major retailers, including grocery chains and big-box stores. This change started when IAMS was purchased by Proctor & Gamble, who made some changes to lower costs. Unfortunately, the result was reduced quality and a class-action lawsuit. Luckily, once Mars Inc. purchased IAMS, the quality improved, though its still conveniently available at big-box chains.

Pros

• Theyve been around for over 70 years
• IAMS makes blends for cats of all ages and situations
• Backed by the largest pet food brand in the world

Cons

• The quality dropped when the company was first sold

About Purina

With a wide range of products sold around the globe, Purina is one of the most well-known of all pet food brands. They have offerings for cats and dogs of all life stages, intended to help prolong your pets life with optimal nutrition.

Some of the blends they offer include Purina ONE, Purina PRO PLAN, and Purina BEYOND. These blend natural ingredients and health-boosting nutrients to provide your pet with nutrition that will keep them in peak condition. There are even blends for specific purposes, like the sensitive skin and stomach recipe or the adult urinary tract health formula.

A Pure Start

Purina got its start well over 100 years ago as the Robinson-Danforth Commission Company. You wouldnt recognize that name, but the name they changed the company to in 1902 is more familiar: Ralston Purina. The companys founder, William H. Danforth, picked the name in hopes that it would signal the purity of the food to potential customers.

Merging With Nestle

Almost exactly 100 years after the Robinson-Danforth Commission Company changed its name to Ralston Purina, the company merged with a subsidiary of Nestle, forming the Nestle Purina PetCare Company. While a lot has changed for the company in that time, one thing remains the same: their push for purity in pet food. And theyve continued to work towards this by fighting against false advertising in the pet food industry.

The 28-Day Challenge

One of the main staples in the Purina lineup is Purina ONE. But theres something unique attached to Purina ONE, the 28-day challenge. Purina is so certain that youll see a difference in your cat in just 28 days of feeding them Purina ONE that they will refund you the purchase price of the food if you dont see a healthier, happier cat. Theyll even send you a coupon for a discount on your first batch to make it easier to try the 28-day challenge.

Pros

• Will refund your money if you dont see a difference in your cat
• Theyve been in business for over a century
• Wide range of recipes to suit cats of all breeds, sizes, and lifestyles

Cons

• The name is advertising to make you think the food is pure

The 3 Most Popular IAMS Brand Cat Food Recipes

1. IAMS Proactive Health High Protein Adult Dry Cat Food

One problem with many dry cat foods is that they tend to lack protein. However, IAMS High Protein dry cat food contains a minimum of 32% crude protein. The first ingredient listed is chicken, followed by chicken by-product meal, ensuring that the protein in this blend comes from quality animal sources.

Despite the quality protein sources, there are some ingredients in here were not particularly fond of. Namely, all the corn ingredients, which can be difficult for some cats to digest. But this food does offer many other benefits. For instance, it has fatty acids to improve your cats skin and coat. Vitamin E will boost your cats immune system, and since this blend is formulated to reduce urinary pH, it will help maintain a healthy urinary system.

Pros

• The main ingredient is a whole-food, animal-based protein
• Contains 32% minimum crude protein
• Fatty acids improve your cats coat and skin
• Vitamin E boosts the immune system
• Formulated to reduce urinary pH

Cons

• Uses quite a few corn products

2. IAMS Proactive Health Weight & Hairball Control Dry Cat Food

With so many cats today becoming overweight or obese, the IAMS weight and hairball control dry cat food is a great way to ensure that your cat doesnt. Its formulated to help maintain an indoor cats healthy weight since theyre generally less active than outdoor cats. Thats why youll notice L-carnitine on the ingredients list; its helping to burn fat and keep your cat trim.

This recipe also contains natural fibers to help reduce hairballs. Even better, because the kibble has a crunchy texture, it will help clean your cats teeth and keep them free of tartar. On the downside, theres still too much corn in this blend for our preferences, though youre likely to find similar ingredients in most dry cat foods.

Pros

• Contains natural fibers to reduce hairballs
• This formula has L-carnitine to help burn fat
• Cleans teeth while your cat eats

3. IAMS Perfect Portions Healthy Grain Free Wet Cat Food

The IAMS perfect portions wet cat food comes in small, individually packaged servings that are the perfect size for most cats. This ensures that your cat isnt overeating, helping to avoid them becoming overweight.

Taking a look at the ingredients list reveals that this food is loaded with great animal protein. With just 0.9% carbohydrates, you dont have to worry about feeding your cat anything that doesnt sit well with them. On top of that, this blend is completely grain-free, so its easy for any cat to digest.

The only downside to this wet cat food is the price. When you look at the portion sizes, there are 1.3 ounces in each portion. Two portions are just 2.6 ounces, compared to the 3-ounce servings from many other brands. When you factor that into the price difference, youll see that the IAMS wet cat food is more expensive than similar products.

Pros

• Portions are ideally sized to maintain a healthy weight
• Very low in carbohydrates
• Contains multiple sources of animal protein
• The grain-free formula is easy to digest

Cons

• More expensive than alternatives

The 3 Most Popular PURINA Brand Cat Food Recipes

1. Purina Pro Plan LiveClear With Probiotics Allergen Reducing Cat Food

Cats are obligate carnivores, which means that they get all of their nutrition from eating animals. Because of this, protein is one of the most important nutrients for a cat to consume. The Purina Pro Plan LiveClear food is packed with an impressive 36% crude protein, making it one of the most protein-rich dry cat foods weve seen.

What makes this food special is how it reduces the allergens your cat gives off, reducing the likelihood of allergic reactions to your cat. It does this by reducing allergens in your cats hair and dander and neutralizing common cat allergens in their saliva.

Of course, this type of special blend doesnt come cheap. Luckily, its backed by a money-back guarantee, so you can rest assured it will work or you wont have to pay for it.

Pros

• Reduces allergens in your cats hair and dander
• Neutralizes common cat allergens
• Backed by a money-back satisfaction guarantee
• Contains an impressive 36% crude protein

2. Purina ONE True Instinct High Protein Natural Wet Cat Food

The Purina ONE True Instinct High Protein Natural Wet Cat Food is advertised as having zero fillers, which is something that all pet parents would appreciate. Taking a look at the nutritional label, we can see that this food is packed with protein. 11% may not seem high, but remember, 80% of this food is just water.

To get such a high amount of protein in this food, multiple sources of animal protein were used, which will provide your cat with a diverse amino acid profile. But after analyzing the first few ingredients, we noticed wheat gluten. Weve seen other wet cat foods without it, so we have to ask whether this is really a necessary ingredient or one of the fillers that Purina says is absent from this blend.

Pros

• Made with zero fillers
• High in protein
• Multiple sources of animal protein

Cons

• Wheat gluten doesnt belong in a wet cat food

3. Purina Cat Chow Naturals Original Dry Cat Food

Any food with naturals in the name tends to cost an arm and a leg, but the Purina Cat Chow Naturals is a different story. This food is affordably priced but still packed with the nutrients your cat needs. For example, it contains a minimum of 34% crude protein, ensuring that your cat will never be deficient.

But this food contains more than just protein. It also has vitamin E to keep your cats immune system in top condition and omega-6 fatty acid to keep its coat and skin looking and feeling healthier than ever.

We expect to see some sort of filler in any dry cat food, but this recipe lists corn gluten meal as the second ingredient. This is a filler protein that boosts the foods protein content. However, its difficult for cats to digest, so they cant utilize the protein as well as animal protein.

Pros

• Affordably priced
• Contains 34% minimum crude protein
• Vitamin E helps boost the immune system

Cons

• Corn gluten meal is the second ingredient

Brand IAMS VS Purina Comparison

Both of these companies produce wet and dry cat foods for cats of all stages and situations. From kitten food to specific blends that are meant for cats with urinary health issues, theres a recipe available from one of these brands thats the ideal fit for every cat. The issue is determining which brand is the right fit for you. So, lets take a look at the differences that define these companies so you can be more informed about which one is right for you and your feline.

Ingredients

Depending on which product from either company you look at, youll see wildly different ingredient lists. While both companies use quality ingredients as well as fillers, we feel that IAMS tends to use better ingredients overall. We noticed that there seemed to be more fillers used in many of the Purina products. Similarly, IAMS seems to use more animal-based ingredients than Purina does. Since cats are obligate carnivores, we always prefer recipes that prioritize animal-based ingredients rather than plant-based ones.

At Catster, weve admired Hepper for many years and decided to take a controlling ownership interest so that we could benefit from the outstanding designs of this cool cat company!

Nutritional Content

Again, there were drastic differences in the nutritional content of various products, even from the same company. It appears that Purina often includes more overall protein than IAMS. That said, we think a lot of it is coming from fillers like corn gluten meal since Purina doesnt use as many animal ingredients.

When it comes to beneficial extras, both companies offer plenty. But to us, it seems like IAMS includes more helpful nutrients in each recipe, such as omega fatty acids and additional vitamins.

Price

You have to be very careful to compare similar products when looking at price. For most cat foods, IAMS tends to be the more affordable brand. But there were some incidences where the Purina foods were more cost-effective. For example, the IAMS wet cat foods are a bit expensive for what you get, especially compared to Purina. But if you compare dry cat foods, youll get a different story because the IAMS is generally cheaper.

Versatile Offerings

If youre looking for a special blend to serve a specific purpose, are you more likely to find it with IAMS or Purina? Here, we think Purina is the clear winner. Both brands offer a wide range of versatile recipes, but Purina has more offerings to pick from. Theyve got all the bases covered, from urinary tract health, to dietetic management, to special foods that reduce the number of allergens your cat is releasing.

Conclusion

For us, IAMS is the winner because they use more animal-based ingredients with beneficial additions in each blend. But Purina still makes some excellent products, and were certain that many people might prefer Purina for its wider range of specialty products. Either way, you should be informed enough at this point to decide for yourself and your feline. Whatever your choice, we stand behind you 100%.
