Royal Canin Ultra Light Canned Weight Loss Cat Food Review


Protein: 9.0% (min) | Fat: 1.6% (min) | Fiber: 2.1% (max) | Moisture: 84.5% (max)

Rated (at the time of writing) as our number one suggestion for the best weight loss cat food, it goes without saying that this formula is SUPER effective. Royal Canin (well known as one of the best cat food brands) have pushed the bar even higher again, creating a high-protein, low-calorie formula that helps cats lose weight in a controlled, balanced manner.

As for flavor, cats love this food as much as a regular formula, which is rare. The thin slices in gravy do wonders to release aromas that keep cats coming back for more.

“Ultra light” really is a fitting description since this formula comes in with one of the lowest-calorie counts you’ll find in over-the-counter cat food. We’ll get into more detail on that and the feeding guidelines shortly, first, let’s look at what’s in it.

Nutritional Information

Designed to offer a balanced, complete diet with a minimal amount of calories, this formula focuses on protein above all else. Chicken, chicken liver, pork, and pork liver make up the bulk of the animal-ingredient content, and the fat level still remains as low as 1.6%. Protein comes in at 9.0%, or in dry-matter terms, 58.0%!

On top of these super-impressive macronutrient ratios, the food remains packed with nutrients and vitamins to support healthy living. The inclusion of L-carnitine helps to fight off weight gain by promoting natural fat burn.

Caloric Density and Feeding Guidelines

Our Verdict

This formula is Royal Canin at their usual impressive selves. It is an incredibly low-calorie food that has to be one of the most effective weight loss cat foods ever produced.

Pairing this food with a cheaper dry weight-loss should yield impressive weight loss results without breaking the bank. We can’t sing it’s praises highly enough.
