If you have a sedentary cat or one who simply loves to chow down, Hill’s Science Plan Perfect Weight Adult Cat Food is a great way of providing your four-legged friend with a delicious and balanced low-calorie meal. The best cat food for weight management, Hill’s Science has an outstanding reputation for creating nutritionally complete dishes that are backed by research.

With over 50% of pets being overweight, a kibble with a blend of ingredients that help cats lose weight while still retaining muscle is essential to ensure they stay fighting fit. Over 70% of cats lost weight after 10 weeks of being fed Hill’s Science Plan Perfect Weight Adult Cat Food, which is why it gets our tick of approval. Let’s take a closer look at this healthy dry cat food to see if it’s right for your feline friend.  

Hill’s Science Plan Perfect Weight Adult Cat Food: Features

Hill’s Science Plan Perfect Weight Adult Cat Food is a satisfyingly crunchy kibble with a rich chicken taste your cat is sure to love. Unlike Whiskas 1+ Dry Cat Food, which is affordable but less nutritious, Hill’s Science has a higher price tag but comes packed with real quality ingredients.

Free of chicken by-products, this kibble has real chicken as its first ingredient along with beet pulp and flaxseed to add fiber for fullness and to aid digestion. Vegetables, such as broccoli and carrots, add a dose of vitamins, minerals, and antioxidants, and there are also cranberries for urinary health. We also love the addition of L-Carnitine and coconut oil, both of which help support a cat’s metabolism for healthy body weight.

This clinically proven formula is designed to be high in protein to keep your kitty full while being lower in calories than other kibbles. It’s been shown to be a safe and effective way to help cats stay within an optimal weight range and is particularly good for sedentary, senior, and indoor cats who may not get the exercise they need. 

With just 300 calories per cup, more than 70% of cats lost weight when fed this kibble over 10 weeks. It’s also free from artificial colors, flavors, and preservatives, so you can be sure you’re giving your kitty the best nutrition possible.

Hill’s Science Plan Perfect Weight Adult Cat Food: User reviews

With close to 5,000 reviews on Amazon and a star rating of 4.8 out of 5, it’s clear that Hill’s Science Plan Perfect Weight Adult Cat Food is a hit with pet parents and felines alike. It’s a similar story across all the main pet food retailers, where this healthy kibble consistently ranks as one of the best cat food products on the market.

Almost all reviewers note positive changes in their cat’s weight with one saying “My little baby Mac has lost 2lbs thanks to this cat food!!! He’s been eating it for 2 months now and he was 22lbs at the beginning, now he’s 20lbs!! Never thought we’d be able to find something that actually works like this does!” while another reviewer writes “I'm very pleased with this diet from Hills. My cat has been on it for 10wks and has lost about 4.5lbs.”

While the negative reviews of this product are limited, those pet parents that gave a low rating cite the taste of the product and the large kibble as the main drawbacks. Just like us humans, cats have their preferences when it comes to food, so if your cat doesn’t like the chicken taste there are other weight management products on the market you can try. If you have a senior cat or a kitty with dental issues, a wet cat food weight management option can be a good solution.

Should you buy Hill’s Science Plan Perfect Weight Adult Cat Food?

If you’re after a safe and effective way to help your cat shed some pounds then Hill’s Science Plan Perfect Weight Adult Cat Food is well worth a try. Full of quality ingredients, this kibble is low on calories while still being high in fiber and flavor to leave your kitty feeling satisfied.

While it’s not the cheapest kibble on the market and some cats may get bored with the chicken flavor, this scientifically-designed formula has been proven to help kitty’s shed weight gently while still keeping their muscles lean and strong. Overall, we recommend this kibble for any pet parent who’s wanting to keep their cat within a healthy weight range.
