Summary

Regal Lean Cat Recipe is a reduced-calorie dry cat food for weight management and senior maintenance in less active or overweight adult cats.
The first ingredient is chicken meal, supported by whitefish meal, dried eggs, shrimp meal, and menhaden fish meal, forming a diverse multi-source animal protein base.
The formula delivers 28% crude protein and 8–10% crude fat, aiming to preserve lean muscle mass while minimizing fat accumulation during calorie restriction.
Multiple whole grains, including brown rice, sorghum, millet, and oatmeal, provide energy and fiber, while beet pulp and flaxseed offer additional digestive support.
Pea protein appears in the mid-ingredient list and contributes additional plant-based protein, which is lower in digestibility and amino acid completeness than animal protein.
Probiotics such as Lactobacillus acidophilus (10 million CFU/lb) and fibers like beet pulp and seaweed meal help support gastrointestinal health and nutrient absorption.
The formula includes 0.7% omega-3 fatty acids, 400 ppm glucosamine for joint support, and chelated minerals like zinc proteinate and manganese proteinate to enhance mineral bioavailability.
Ash content is 7.2%, with moisture at 10%, indicating a moderate mineral load consistent with many weight-control formulas.

Pros
Expand All
1

Moderated calorie profile

With fat capped at 10% and protein at 28%, the formula helps manage weight without compromising muscle maintenance.
2

Multi-source animal proteins

Chicken meal, whitefish meal, dried eggs, shrimp meal, and fish oil create a balanced amino acid profile and enhance palatability.
3

Digestive health support

Contains probiotics and prebiotic fibers (beet pulp, flaxseed, dried seaweed) to maintain a healthy gut microbiome and promote digestion.
4

Functional additives

Includes 0.7% omega-3 for anti-inflammatory benefits and 400 ppm glucosamine to support aging joints.
5

Chelated minerals included

Zinc and manganese proteinate enhance mineral absorption and contribute to overall metabolic health.
Cons
Expand All
1

Includes plant protein

Pea protein contributes non-meat protein, which may dilute the overall amino acid quality compared to a fully animal-sourced formula.
2

Relatively low fat

While weight control benefits, the 8–10% fat content may not satisfy more active or underweight cats.
3

Grain-inclusive formulation

This formulation uses brown rice, millet, oatmeal, and sorghum, which may be unsuitable for cats with grain sensitivities.
4

No fresh meat ingredients

The absence of fresh or raw meat sources means the food relies entirely on rendered meals and dehydrated proteins.
5

No natural taurine source listed

Taurine appears only as a supplement and is not derived from natural organ meat components.

How the score is calculated?

The actual calculation of the score is based on sophisticated and advanced algorithm that takes into account multiple parameters.

To simplify the explanation, the calculation is based on three main criteria:

(1) Amount of protein (more is better)

(2) Amount of carbohydrates (less is better)

(3) Quality and source of ingredients.

Based on that 3 main criteria, 9 score calculation rules are used to compare the different foods.

One major assumption is that the closer an ingredient is to the top of the ingredient list, the greater its relative weight and contribution to the food.

In general, cat food is composed of protein, fats, carbohydrates, fibers, vitamins, and minerals.

Protein is the most important component in a cat's diet, and cats primarily get their protein from animal meat.

Fat is a primary source of energy and essential fatty acids.

Carbohydrates are controversial in a cat's diet, as cats are obligate carnivores and typically consume very few carbohydrates.

Fibers play an important role in digestion and food absorption, and vitamins and minerals are essential for different organism functions.

Dry matter values are used to compare the amount of nutrients in different cat foods. This means that moisture is excluded from the equation to provide a more accurate comparison.

Putting all of these and more into a formula results in a product score.

The maximum score a cat food can receive is 100. Points are added or removed based on the score calculation rules.
