Protein: 31.0% (min) | Fat: 13.0% (min) | Fiber: 6.0% (min) | Moisture: 8.0% (max)

Hill’s Science Diet has established itself as one of the leading cat food ranges in the world. They’ve been at the leading edge of pet nutrition for over 70 years now, so it’s no surprise that this indoor chicken recipe gets such a good reception from cat owners. Hill’s formulas are one of the most common cat foods sold at veterinary practices, giving them a good stamp of approval from those in-the-know.

Manufactured in the USA, each ingredient Hill’s include is tested to strict standards and meets all nutritional requirements. This adult indoor formula is one of our top picks for dry cat foods and is specially formulated for cats between the ages of 1 and 6. There’s also a variant of the formula available for senior cats aged 7+.

We’d highly recommend this food for indoor cat owners, and would even stretch to say it’s great option for outdoor cats who need to shed a few pounds. You can always adjust the portion sizes to account for differences in lifestyle.

Nutritional Information

This particular formula recently saw a few ingredient changes, with the protein content boosted from 29.5% up to 31.0%, and the fat content lowered from 16.0% to 13.0%. Real chicken remains the number one ingredient, and Hill’s avoid using any artificial flavorings or preservatives.

Crude fiber content ranges between 6.0% and 12.0%, which is more than enough to see some positive effects on digestion and a reduction in hairball occurrence. Tarine content comes in at 0.1% min, and 500 IU/kg min of Vitamin E will work wonders to keep skin healthy.

Caloric Density

At 319 kcal/cup, it’s clear that Hill’s have made an effort to keep the calorie count down low. A modest 319 calories per cup is at the low end of the scale for cat foods in this category. Feeding guides will, of course, account for this, so expect to dish out more per serving than you would an average dry cat food.

Despite being an indoor formula, this food is suitable for outdoor cats too, but you’ll need to adjust the feeding amounts according to their level of activity. The recommended portion sizes are as follows:

4 lb1/3 cup
5 lb3/8 cup
8 lb5/8 cup
