Which Iams cat food is best?

You want to feed your cat the very best, so you’ve probably come across Iams as healthy and affordable cat food. Because there are multiple formulas and types, you may be wondering which is best.

The best Iams cat food provides the nutrients your cat needs based on its age, physical condition and taste preferences. For a cat-approved food that supports a healthy weight and reduces hairballs, Iams Proactive Health Adult Indoor Weight & Hairball Care is the best.

What to know before you buy Iams cat food


Iams makes both wet and dry cat food. The best texture often comes down to your cat’s preference.

  • Dry: Many pet owners start with dry food because it makes less mess and can be easier if your cat likes to graze throughout the day.
  • Wet: Wet food is easier to chew and digest, ideal if your cat has trouble with its teeth or jaws. Some pet owners give their cat pate or chunky wet food as an occasional treat or on top of their dry food.


Larger packages can be less expensive as long as your cat will eat all of the food. If you are trying out new food, start with a smaller package, such as 3.5 pounds. Once you’re sure your cat will not have a reaction and likes the food, larger bags are usually cheaper per ounce. Just make sure you can store it in an airtight container to prevent it from getting stale.


Iams formulas are made with protein as the first, and therefore largest, ingredient. This works well for cats, who are carnivores in the wild. Fat, carbohydrates and fiber are also important components included for your cat’s health, along with vitamins and minerals. Each formula comes with specific feeding recommendations based on weight.

What to look for in quality Iams cat food


For most cats, high-protein cat food is the best source of energy. Chicken, turkey and salmon are common protein sources because of their tasty appeal to cats. Eggs are often included as another source of protein.

Added nutrients

Look for Iams cat food with nutrients that help your cat’s systems. These can be vitamins and minerals to support their age and development, such as added antioxidants and fiber for older cats or nutrients and prebiotics that mimic mother’s milk for kittens.

Specialized needs

Iams is known for having reliable cat food that targets your cat’s dietary needs. The Proactive Health line combines common nutritional needs, such as the correct ratio of protein, fat and carbohydrate, with specialized formulas, such as a lower pH to support urinary health. The Long Hair Care formula works for cats whose coats require extra attention by keeping their skin healthy and reducing hairballs.

How much you can expect to spend on Iams cat food

Iams cat food costs $10-$40. Larger sizes run higher initially, but often end up less expensive per pound.
