Hill’s Science Diet Adult Perfect Weight Cat Food Review


Protein: 36.0% (min) | Fat: 8.5% (min) | Fiber: 10.0% (max) | Moisture: 8.0% (max)

This Hill’s Science Diet formula is designed to help overweight cats lose weight, and healthy weighted cats maintain weight. Our focus for this review is on its weight loss abilities rather than it’s maintenance abilities, and we’re mightily impressed. We think it’s one of the best cat foods for weight loss available.

Weight loss in cats needs to happen at a controlled pace and through a balanced diet. Feeding too little of a regular food could leave cats malnourished and lacking in essential acids they require in order to stay healthy. This formula is created to allow for fewer calories to be consumed while maintaining a balanced diet.

Since it’s a formula created by such a reputable brand, you get all the peace of mind and confidence that this provides a 100% nutritionally complete meal. On top of providing a complete meal, the effectiveness of this weight loss formula is quite amazing. It’s easily one of our recommended top cat foods for weight loss.

Nutritional Information

Hill’s Science Diet’s unique blend of ingredients aims to promote a return to a healthy weight while retaining lean muscle mass. A dry-matter protein content of 40.0% supports this goal and represents a very good level of protein, considering the relatively low-calorie count.

The number one ingredient is chicken, and as always, you’ll find no artificial flavors, colors, or preservatives. A vitamin and antioxidant blend works to promote a healthy immune system and works wonders to boost coat health.

Caloric Density and Feeding Guidelines

300 kcal/cup

At 300kcal/cup, this food achieves an impressively low-calorie count given the protein content. A low calorie count per cup will mean your cat will full and satisfied despite consuming far fewer calories than you’d expect; this is usually much more effective than feeding less food.

If you’re feeding with weight loss in mind, you’ll want to stick pretty closely to the feeding guidelines (in cups) suggested by Hill’s:

Our Verdict

Weight loss is the primary goal with a formula like this, of course, but this food’s effect on coat and skin health is very impressive too. For a weight-loss cat food that doesn’t require veterinarian authorization, it’s staggeringly effective when portioned correctly.

We rate this food highly, and Hill’s Science Diet’s excellent track record fills us with confidence regarding the completeness of the formula. At the time of writing, 98% of reviewers on Chewy would recommend this food, and it’s no surprise to us.
