🐾 Pet Macronutrient Ratio Formulator Simulator

Protein Requirement by Species and Life Stage

Growing puppies and kittens need more protein than adults.

• 18%: Adult dog min (AAFCO dry-matter basis)
• 26%: Adult cat min (obligate carnivore need)
• +8–10%: Growth/lactation (above adult maintenance)
• variable: Senior adjustment (kidney status dependent)

Species and life-stage protein need

Placeholder: protein target varies by species, growth stage, and activity level.

Placeholder callout: cats require higher dietary protein than dogs.

Fat Requirement for Energy and Skin Health

Fat is the most energy-dense macronutrient in pet food.

• 5%: Adult dog min (AAFCO dry-matter basis)
• 9%: Adult cat min (AAFCO dry-matter basis)
• linoleic: Essential fatty acids (skin/coat maintenance)
• ~30%: Upper practical cap (palatability & GI limit)

Fat share and essential fatty acids

Placeholder: fat supplies energy and essential fatty acids for coat health.

Placeholder callout: too little fat harms coat and skin condition.

Carbohydrate Role and Tolerance

Carbs are not strictly essential but provide usable energy.

• high: Dog tolerance (flexible digestive adaptation)
• lower: Cat tolerance (obligate carnivore biology)
• 30–50%: Typical dry food (carb remainder share)
• 2–5%: Fiber sub-fraction (supports gut function)

Carbohydrate remainder and tolerance limits

Placeholder: carbohydrate fills the remaining energy after protein and fat.

Placeholder callout: excess carbs can crowd out needed protein.

Balanced Ratio Target Range

A workable diet keeps all three macros inside reference bands.

• 25–40%: Protein band (general maintenance target)
• 12–20%: Fat band (general maintenance target)
• 30–55%: Carb band (derived remainder)
• composite: Balance score (distance from target center)

Target band and balance scoring

Placeholder: balance is scored by closeness to reference macro bands.

Placeholder callout: balanced ratios reduce metabolic strain.

Diet Formulation Feasibility Check

Final check confirms the mix is realistic to manufacture and feed.

• 100%: Sum constraint (protein+fat+carb must total)
• practical: Ingredient limits (sourcing & cost bounds)
• flagged: Palatability risk (extreme ratios reduce intake)
• pass/fail: Final status (feasibility classification)

Feasibility classification of the formulated mix

Placeholder: feasibility checks confirm the ratio can be realistically fed.

Placeholder callout: infeasible mixes need slider readjustment.
