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:

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

• 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.

• 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.

• 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.

• 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.

• Grain-free with no added sugar: Suitable for cats that do better without grains or added sugars while still delivering balanced energy.

Cons:

• 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.

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

• Starchy plant carbohydrates: Despite being grain-free, potato, peas, and potato starch contribute significant starch, which can raise total caloric intake.

• Multiple animal proteins: Chicken, lamb, and hydrolyzed poultry protein make it unsuitable as a single-protein option for elimination diets or sensitive cats.

• 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.

• No declared live probiotic count: The recipe includes prebiotic fibers and yeast, but no guaranteed CFU of live probiotics is provided.
