Hill’s Prescription Diet (Wet) Review

Hill’s Prescription Diet wet cat food is made up of 31 recipes which are not rated due to their intentional therapeutic design.

Although this is a prescription product, our review has nothing to do with the accuracy of claims made by the manufacturer as to the product’s ability to treat or cure a specific health condition.

So, to find out whether or not this product is appropriate for your particular pet, it’s important to consult with your veterinarian.

Each recipe includes its AAFCO nutrient profile: Growth (kitten), Maintenance (adult), All Life Stages, Supplemental or Unspecified.

Ingredients Analysis

Hill’s Prescription Diet Gastrointestinal Biome Stress Chicken & Vegetable Stew Cat Food (formulated for digestive and fibre care).

This food has been chosen as a representative of the range, even though each recipe may be designed for different veterinary conditions.

The first ingredient is chicken broth. Broths are of only modest nutritional value. Yet because they add both flavor and moisture to a cat food, they are a common component in many wet products.

The second ingredient is chicken which is considered “the clean combination of flesh and skin… derived from the parts or whole carcasses of chicken”.¹ Chicken is naturally rich in the 11 essential amino acids required by a cat to sustain life.

The third ingredient is pork liver, an organ meat sourced from a named animal and thus considered a beneficial component.

The fourth ingredient is carrots which are rich in beta-carotene, minerals and dietary fiber.

The fifth ingredient is rice starch, a starchy powder extracted from rice and most likely used here as a thickening agent.

The sixth ingredient is wheat gluten. Gluten is the rubbery residue remaining once wheat has had most of its starchy carbohydrate washed out of it. Compared to meat, glutens are inferior plant-based proteins low in some of the essential amino acids dogs need for life.

This inexpensive plant-based ingredient can significantly boost the total protein reported on the label — a factor that must be considered when judging the actual meat content of this cat food.

The seventh ingredient is spinach. Due to its exceptional vitamin and mineral content, spinach exhibits a remarkably high nutrient Completeness Score[1. Completeness Score is a measure of a food’s relative nutrient content and is computed by NutritionData.com from the USDA’s National Nutrient Database for Standard Reference] of 91. For cats who are predisposed to oxalate stones spinach should be avoided, due to it’s high oxalate content.

The eighth ingredient is ground pecan shells, a low-cost, low-quality source of insoluble fiber. Fiber can help support healthy digestion and improve stools.

From here the list goes on to include a number of other items. But to be realistic, ingredients located this far down the list (other than nutritional supplements) are not likely to affect the overall rating of the product.

However, there is one notable exception. . . this recipe includes dried beet pulp, a controversial ingredient, a high fiber by-product of sugar beet processing. Some denounce beet pulp as an inexpensive filler while others cite its outstanding intestinal health and blood sugar benefits.

We only call your attention here to the controversy and believe the inclusion of beet pulp in reasonable amounts in most cat foods is entirely acceptable.

Has Hill's Prescription Diet cat food been recalled in the past?

Yes, there have been several recalls. Details can be found on the Dog Food Advisor, but in summary:

In 2007, there was an industry-wide recall which impacted Hill’s Science, due to food being contaminated with melamine. The contamination resulted in severe sickness and death among cats and dogs. 

In 2014, there was another recall of Hill’s Science Diet dog food, due to potential salmonella contamination.

A year later, Hill’s initiated a market withdrawal which affected several dog food varieties. The recall was a result of labeling issues. 

In late 2019, Hill’s was also forced to recall canned dog food from their Prescription and Science Diet lines. This was a result of unusually high vitamin D content. High vitamin D levels cause blood calcium to rise, resulting in organ failure and possibly death. 

However, this did not just affect Hill’s Science Diet. About two months later, other pet food brands were recalled over vitamin D-related issues.
