Feeding Tips
- •Split daily amount into 2 meals for better digestion
- •Adjust portions based on your pet's body condition over time
- •Treats should not exceed 10% of daily caloric intake
- •Always provide fresh water alongside meals
How we calculate: We use the standard veterinary formula RER = 70 × (weight in kg)0.75, then multiply by a life stage and activity factor to get your pet's Maintenance Energy Requirement (MER). This is the same formula used by veterinary nutritionists worldwide.
