Summary

MERA Cats Nature Adult Lamb is a grain-free dry food for adult cats that emphasizes high animal-protein nutrition while supporting digestive comfort, skin and coat health, and urinary balance.
The first ingredient is dried chicken protein (including 20% from animal-welfare farms), establishing poultry as the primary protein source, with fresh lamb (14%) contributing palatability and amino acid variety.
Of the total protein, 80% is animal-derived, aligning with feline carnivorous needs and helping maintain lean muscle mass.
At 32% crude protein, 18% fat, and 16.37 MJ/kg metabolizable energy, the formula is energy-dense for active adults and should be portioned mindfully for cats prone to weight gain.
Poultry fat, salmon oil (0.8%), linseed (2.5%), and sunflower oil provide omega-6 and omega-3 fatty acids (3.5% and 1.2%, respectively) that help maintain a healthy skin barrier and glossy coat.
Digestive health is supported by beet pulp, apple pomace, lignocellulose, brewer’s yeast, and chicory inulin (0.2%), which supply a blend of fermentable and insoluble fibers to promote good stool quality and nourish beneficial gut microbes.
DL-methionine (3000 mg/kg), magnesium at 0.1%, and a defined mineral profile (calcium 1.6%, phosphorus 1.15%) help manage urinary mineral balance and support a favorable urine pH environment.
The ash content is 8.6%, reflecting the formula’s mineral contribution from animal tissues and fortified micronutrients.
Grain-free carbohydrates from potato, peas, and potato starch provide digestible energy without grains or added sugar, though they still contribute starchy calories.
Taurine at 2000 mg/kg, plus vitamins A (16,000 IU), D3 (1,600 IU), E (300 mg), and C (100 mg), support vision, cardiac function, immune competence, and antioxidant defenses.

Pros
Expand All
1

High share of animal protein

80% of the total protein comes from animal sources, supporting a complete amino acid profile for muscle maintenance.
2

Omega fatty acid support

Omega-6 at 3.5% and omega-3 at 1.2% from salmon oil, poultry fat, linseed, and sunflower oil promote skin health and coat sheen.
3

Urinary tract balance

DL-methionine (3000 mg/kg) and controlled minerals (magnesium 0.1%, calcium 1.6%, phosphorus 1.15%) help maintain a urine environment less conducive to crystal formation.
4

Digestive fiber and prebiotics

Beet pulp, apple pomace, lignocellulose, brewer’s yeast, and chicory inulin (0.2%) aid stool quality and support beneficial gut bacteria.
5

Targeted micronutrients

Taurine (2000 mg/kg) and antioxidant vitamins A, D3, E, and C help sustain heart and eye function, immunity, and oxidative stress defense.
6

Grain-free with no added sugar

Suitable for cats that do better without grains or added sugars while still delivering balanced energy.
Cons
Expand All
1

Higher mineral load

An ash content of 8.6% with calcium at 1.6% indicates a relatively mineral-dense formula, which may warrant consideration in cats needing tighter mineral control.
2

Calorie- and fat-dense

With 18% fat and 16.37 MJ/kg, careful portioning is advisable for less active or weight-prone cats.
3

Starchy plant carbohydrates

Despite being grain-free, potato, peas, and potato starch contribute significant starch, which can raise total caloric intake.
4

Multiple animal proteins

Chicken, lamb, and hydrolyzed poultry protein make it unsuitable as a single-protein option for elimination diets or sensitive cats.
5

Marine omega-3s not quantified

While salmon oil is included at 0.8% and total omega-3 is stated, EPA/DHA levels are not specified.
6

No declared live probiotic count

The recipe includes prebiotic fibers and yeast, but no guaranteed CFU of live probiotics is provided.

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.
