Purina has a long history of creating excellent cat food formulas that are as affordable as they are effective. With their weight management formula, they’ve created a food that rivals the best in terms of weight loss ability while remaining cost-effective. We rate it as one of our favorite diet cat foods available.

At a glance, the value offered doesn’t seem mind-blowing, but this food is relatively calorie-dense for weight-loss cat food. This means you’ll be using less of it per meal than you would a lighter-calorie option. Though you might imagine this would leave a cat unsatisfied, the exceptionally high protein content in this food will result in a stomach that feels full, even though it isn’t!

As we write this, Chewy’s reviews section details that 99% of the 153 reviewers would recommend this food, making it one of the highest rated cat foods available today. That incredible number speaks volumes about the food’s effectiveness as a weight-loss food and its appeal to cats.

Nutritional Information

This weight management formula from Purina has a pretty impressive dry-matter protein content of 52.3%. A high protein content is excellent in a weight-loss food and will promote lean muscle retention as fat burns away.

Since this premium cat food formula comes from industry titans Purina, you can rest assured it exceeds all the minimum dietary requirements set by the standards bodies in the USA.

Caloric Density and Feeding Guidelines

3,819 kcal/kg, 1,735 kcal/lb, 427 kcal/cup

At 427kcal/cup, it’s hardly light on calories. This beefiness may surprise you in a weight-loss food, but given the correct portioning, it’ll just mean the bag of kibble lasts longer. It’s part of the reason why this food offers such excellent value for money when compared to its competitors.

Obviously, since it’s relatively high in calories, you’ll want to be modest with the portion sizes. Interestingly, Purina suggests that you free-feed the food to your cat. We’re not entirely on board with this, since it encourages overfeeding, so we’d advise on continuing with your usual meal arrangements. Here are the portion recommendations (in cups) from Purina:

WeightMaintenance10% Calorie Reduction
5 – 9 LBS1/3 – 2/31/4 – 1/2
10 – 14 LBS2/3 – 11/2 – 3/4

Our Verdict

Possibly offering the best value of any weight-loss cat food formula available today, it’s one worth trying. Due to the calorie-dense nature of the food, it’s possible your cat will object to the smaller portion sizes required. If this is the case, we’d recommend pairing this food with light-calorie canned food and adjusting the portion sizes accordingly.

It’s a superb formula that has clearly resonated with the demands of overweight cat owners given the excellent reviews.
