We detect organs and tissues in the composition and explain their nutritional value. Universal biology — independent of the source animal species.
Biological facts are universal — liver always provides vitamin A, regardless of whether it comes from beef, chicken or ostrich. Matching to your composition is automatic.

ADDITIVE ANALYSIS · HOLOPET REVIEW
Our additive analysis confirms a clean-label profile: no artificial preservatives, colorants, or flavours are present among the 10 declared additives. No controversial additives were identified in our scan. On the vitamin side, preferred high-bioavailability forms are used — including retinyl acetate for Vitamin A, cholecalciferol for Vitamin D3, and taurine as a supplemented amino acid — which our analysis recognises as well-chosen nutritional additions. Mineral sourcing is mixed: copper and manganese are supplied as organic chelates, which are generally better-absorbed forms, while zinc is provided as zinc sulphate (a standard inorganic salt), and selenium and iodine are also in standard inorganic forms — a common industry practice that is nutritionally adequate, though organic chelated forms are typically considered preferable where available.
We show what the manufacturer declared in the "Additives" section (supplementation). The natural contribution from ingredients is not computed — we don't know it.

COMPLIANCE
FEDIAF compliance
We compare the guaranteed analysis on the label against FEDIAF minimum requirements for this species and life stage (per 1000 kcal of energy).
ME: 379 kcal/100g — computed from macronutrients (FEDIAF 2025), as the manufacturer did not state it

SodiumPotassiumMagnesiumIodineEPA + DHA
The manufacturer did not include these in the guaranteed analysis. No declaration ≠ a deficiency — we simply don't know them.
We check the guaranteed-analysis nutrients on the label, converted to per 1000 kcal. The exception is taurine (critical for cats): when it is absent from the analysis, we show "≥" — the amount declared in the "Additives" block (the supplement), because the natural taurine from ingredients is unknown. Other vitamins and trace minerals from the "Additives" block are not counted here. This is not veterinary advice.
