Hill’s Science Diet specializes in science-backed formulas for a vast range of conditions. With their dry senior cat formula, we think they’ve created one of the best foods for older cats available today, and possibly one of the most effective cat foods in general.

At the time of writing, an impressive 95% of reviewers on Chewy would recommend this food. Featuring excellent ingredients that help older cats in a whole host of ways and a price tag that puts most competitors to shame, it’s no surprise it’s highly rated.

Aimed at cats 11 years or older, this senior formula is manufactured in the USA and offers a balanced, complete diet in a kibble that cats go crazy for.

Nutritional Information

Hill’s Senior formula features chicken as the main ingredient, pulling in a 28.0% protein content and an 8.0% moisture content, equating to roughly 30.0% dry-matter protein content. Fiber remains unchanged at 3.5% max despite a recent formula tweak, along with fat content at 18.0%.

All in all, this formula provides a complete and balanced diet that’ll cater to all of your older cat’s needs. There are no artificial flavorings, preservatives, or additives, and the antioxidant blend works wonders to support a healthy immune system.

Caloric Density and Feeding Guidelines

At 510 kcal/cup, this is a pretty calorie-dense cat food, especially given that senior cats require fewer calories per day compared to their younger counterparts. A calorie-dense means that paying attention to the feeding portion guidelines is especially important. Your previous food may have had far fewer calories in a serving of the same size.

Hill’s Science Diet recommends the following portions, though these should be adjusted according to your cat’s individual needs. Consult your veterinarian if you require help with a feeding plan.

4 lbs1/3
6 lbs1/2
8 lbs5/8
10 lbs2/3
12 lbs3/4
14 lbs7/8
16 lbs1

Our Verdict

Hill’s Science Diet has done it again, producing one of the best cat foods around, and certainly one of the best cat foods for older cats. Packed with helpful minerals, vitamins, and fatty acids, this food has everything you could want and more.

Considering the value for money offered here, this food is absolutely perfect for feeding alongside a senior canned food. We highly recommend it.
