Science Diet Cat Food Reviews

Hill’s Science Diet is perhaps one of the most widely available premium and specialist cat foods available on the market today. The brand has attracted praise for its availability everywhere, but others complain that their cats experience skin problems while using the formulas long-term. Cats are known as obligate carnivores and require a large amount of protein in the diet, and, as a result, they have trouble digesting most plant-based ingredients, including corn, grains, gluten and soy.

Hill’s Science Diet has a lot of these ingredients in their formulas, and most of them quite prominently. In addition to this, its meat sources are of a questionable quality, as they are all from by-products instead of real meat. Using our Science Diet cat food reviews, you can get a look at some of the individual formulas and decide for yourself whether they are suitable for your kitty.

This being said, their formulas include extra protein, which is supplemented with soy protein meal. However, since cats cannot easily digest it, the usefulness of this extra protein is up for debate.

Hill's Science Diet Adult Urinary Hairball Control Cat Food is a pretty good tasting dry kibble food made from real chicken and all-natural ingredients that is specially formulated for cats. It is part of their more ‘natural’ line of food formulas, which has earned it its top spot on our list.

This particular recipe helps support the health of your cat’s urinary system and tract by providing high levels of added magnesium, which is optimised to promote urinary health. Urinary tract infections are the most common health condition in cats, yet they can easily be prevented. Feeding your cat a food like this regularly can help prevent urinary issues ever coming about, so it is a great formula to have on-hand.

This Science Diet blend is not just a dry food, but it is a functional food and the Adult Urinary Hairball Control formula helps prevent the occurrence of urinary tract problems in cats and also contains fiber to help reduce hairballs, ensuring your cat stays comfortable and calm.

It has an antioxidant and vitamin blend also, which works together to help support your cat’s immune system and improve overall health. It is made from high-quality natural ingredients without the addition of any artificial additives, such as colors, flavors and preservatives.

Pros

  • Contains fiber.
  • Contains natural protein.
  • No additives.

Cons

  • Dry food has no moisture.

This wet food is formulated to support your kitty’s urinary health and reduce the risk of urinary crystal and stone formation. Bladder stones are formed from crystals in the urine which combine to form stone-like structures, sitting in the bladder and can cause urinary problems, including severe pain.

Science Diet’s Feline Multicare C/D formula has controlled levels of magnesium, phosphorus, calcium and oxalate which limits the potential for crystals and stones to build up. Plus, it contains potassium citrate which adjusts urine pH – making it more acidic – helping to dissolve the stones and disrupt the formation of new ones.

It is a chicken and vegetable stew formula which contains what you would expect – chicken as the primary high-quality protein source, along with chicken liver and a mix of vegetables for added nutrition.

Pros

  • Formulated for cats with urinary problems.
  • Uses chicken, which is high-quality protein.

Cons

  • Contains vegetables, which some cats won’t eat.

This is a wet cat food which is specially designed to look after your kitty’s urinary tract and is a great food option if you have a kitty who is currently suffering from a urinary infection. If you have or ever do have this, chances are your veterinarian will recommend this very food, so it is always helpful to have some on hand because kitty urinary problems are common.

This canned food uses high-quality whitefish as its primary protein source, which is also a natural source of Omega-3 fatty acids. Omega-3 fatty acids help promote strong skin and a healthy coat in your kitty, so it is always nice to see this present in cat food. It is a wet food, too, so there is no need to add moisture which may be necessary with the other Hill’s Science Diet dry foods which we have reviewed.

The Hill’s Science Diet range is rather limited and is mostly comprised of these three main product lines, which are geared towards kitties who have some particular health problems. Hairballs and urinary infections are two major problems in cats, and it is something which – as a cat owner – you will almost certainly have to deal with at some point or another.

Pros

  • Contains high-quality protein.
  • High moisture content.
  • No artificial additives.

Cons

  • Cats can have allergies to fish.

The first ingredient in this food is chicken; it is an excellent protein source which provides a high-quality source of dietary protein. Although chicken is full of moisture, this is removed during the cooking process so it is always good to supplement this food with added moisture.

Second in the ingredients list is whole grain wheat. Although wheats and other related ingredients are viewed as unnecessary in cat foods, whole grain wheat is actually desirable in cat foods because it provides lots of nutrients and is a top source of dietary fiber, for better digestive health.

The third most plentiful ingredient is corn gluten meal, a by-product from the production of various corn products such as corn starch and syrup. Whilst this is very high in protein (almost 60%) it is still an inferior protein to meat-based protein, because plant-based proteins are not as easily digested by cats.

Coming in fourth is chicken fat, typically collected whilst cooking the chicken through rendering. Chicken fat is actually a very high-quality protein source and source of essential fatty acids.

Fifth and finally, we have whole grain corn. This is the entire corn kernel in all its glory and provides a modest – but not really useful – amount of vitamins, minerals and plant-based proteins. As a result, it is a controversial cat food ingredient which people try to avoid.

This formula does not contain any artificial colours, preservatives, flavours or unknown meat ingredients, so you know you are only feeding your cat natural ingredients.

Pros

  • Lots of protein for early development.
  • Uses chicken which is a quality protein source.

Cons

  • Contains corn and wheat – potential allergens.

This food provides nutrition which is balanced to help promote dental and complete health in cats. This dry food has technology which has been clinically proven to reduce the build-up of plaque and tartar.

The technology I am referring to us known as interlocking fiber technology which helps to clean your cat’s teeth and freshen breath with each chewing motion. Added to this dry food is an antioxidant blend using vitamins C and E which, again, has been clinically proven to help promote a healthy immune system.

This food is made from quality ingredients which are easy to digest, without using artificial colors, flavors or preservatives at all.

Pros

  • Improves dental health.
  • Uses unique interlocking fiber technology.
  • Balanced nutrition

Cons

  • No moisture.

Science Diet’s dinners chunks & gravy food is a great complementary food which can be added to their dry formulas. These wet foods promote healthy digestion, healthy body weight and has a taste which cats will love.

Through the utilization of carefully balanced nutrition, this food helps promote and maintain healthy body weight. This food is great for kittens, because it promotes healthy growth and provides optimum nutrition. It is available in three different blends – chicken, tuna or ocean fish – so you should be able to find one which your cat will enjoy.

Pros

  • Promotes ideal weight.
  • Nutrition is carefully balanced. 
  • Great formula for kittens.

Cons

  • Protein sources are not the best, but they are still good.

This line of food is available in three different flavours – salmon & spinach, chicken & rice and seared tuna & carrot – and has blends for cats in all life stages, including adult cats, kittens, adults above seven years and adults above eleven years. Each of these respective recipes is formulated specially to meet the needs of cats in those life stages.

These flavours are quite unique and are great for cats who are craving a bit of variety when it comes to meal time. Using natural ingredients, minerals, vitamins and amino acids, these foods are very healthy and contain delicious bites of pure meat and vegetables in a tasty sauce.

Pros

  • Unique flavours provide variety.
  • A healthy choice.
  • Formulas for cats of all ages.

Cons

  • Some cats can have seafood allergies.

​​Hill’s Science Diet Ingredients

Hill’s Science diet uses a wide range of different ingredients, and they tend to differ slightly; it depends on the formula in question. As far as the regular Science Diet formulas are concerned, the main sources of protein is chicken meal. This protein-based ingredient is followed closely by the second ingredient in most of the regular formulas, corn gluten, with ground corn following close behind it in third.

The fats which are contained in most of the Science Diet formulas are not named, and simply referred to as animal fat. Plus, there is “Chicken Liver Flavor” added as an ingredient, which is present in the regular Science Diet formulas available on the market.

Hill’s Science Diet is also available in formulas which are more natural. These natural formulas, which claim to not contain any fillers, have a high-quality whole meat as the primary ingredient, with corn gluten meal following close behind. Soy protein is also present in the “natural” formulas.

Unfortunately, Hill’s Science Diet is a rather corn-heavy food brand, which is terrible news for cats who have food allergies, because corn is a common allergen and can cause allergy symptoms even in cats who do not have a previous history of any allergies or food intolerances. In addition, soy products are also present in some of the Hill’s Science Diet dry cat food blends, usually as soybean oil.

The ingredients across the various Hill’s Science Diet formulas vary, but many of them include chicken and chicken meal as the primary sources of high quality protein. Now, you may be thinking that “chicken meal” doesn’t sound like it is a good protein, but it is! Chicken meal is a super high quality protein source which has a lot more protein than cooked chicken, because chicken loses a lot of its moisture and protein count when cooked.

Who Makes Hill’s Science Diet?

The company responsible for making Science Diet cat food is known as Hill’s Pet Nutrition. Hill’s Pet Nutrition has origins traceable all the way back the late 1930s, when  Hill’s Science Diet was founded by Dr. Mark L. Morris Sr.

Mark was a well-known veterinarian and had ambitions of formulating a dog food to help save the life of his friend’s blind guide dog. After a lot of work. Today, Hill’s Science Diet formulas are widely sold and promoted by veterinarians for their health benefits and special food blends, which are targeted towards health problems. Later on, the Science Diet brand we are reviewing today was created in 1968, by Dr. Mark Morris Jr., the son of the original founder.

Hill’s Science Diet Recalls

In 2007, several of the Science Diet formulas were involved in pet food recalls. It was recalled due to a contamination with melamine. But, although this is not ideal, there do not seem to be any formulas listed on the FDA’s recall website which were recalled after 2007.

The best way to make sure that your cat’s food is safe, I will always highly recommended that you check out the FDA’s dedicated pet food recall website, which will help you to stay updated on the latest pet food recall information.

All About Urinary Health

The most common problem in cats are urinary problems. Unfortunately, a large number of pet owners are not aware of this, but urinary issues and infections in cats are super common.

There are a few causes of urinary problems – from stress to bacterial infections – and they all come with their own unpleasant set of symptoms. In some rare and very extreme cases, they could put your cat’s life at risk

Urinary problems are quite easy to spot in cats. When your kitty is happy and healthy, he or she will use the litterbox for urination and defecation. But, behaviours such as loss of bladder control, urinating outside of the litterbox frequently, straining or a painful cry when urinating are tell-tale signs of a bladder problem.

When your cat shows these signs, it is important to contact your veterinarian and determine whether or not you need to bring kitty into the clinic for a check-up. Usually, urinary problems are caused by crystals in your cat’s diet, which you can sometimes see with your own eyes.

Kitties can and often do suffer from a medical condition known as Crystalluria where small-to-medium sized crystals are present in the cat’s urine. These Crystals can be a warning sign of kidney stones, but crystals are usually present in cats whose urine has recently been saturated with crystallogenic substances.

Crystalluria in kitties who are functioning healthily and have no urinary tract problems are completely harmless, because the crystals are being passed out before they grow large enough to be a problem. It only becomes a problem when they are large and cannot be passed. The only symptom of crystalluria is the presence of detectable crystals in fresh urine.

Hill’s Science Diet Urinary Health formula helps breakdown these crystals and works to improve the inner-workings of your kitty’s urinary tract problems. Urinary problems are often short-lived and they can easily be fixed with the right prescription or medicated food which is high in magnesium and makes your cat’s urine more acidic.
