Feeding calculator
How much food does your pet need?
Estimate a starting portion in grams per day, using your pet’s details and the energy value on the food label.
For healthy adult dogs and cats at a healthy weight. Puppies, kittens, pregnancy, illness, excess weight and intensive work need an individual feeding plan.
How do we calculate it?
RER = 70 × kg0.75. RER × your adult pet’s profile → kcal. (kcal − daily calories from treats (kcal)) ÷ (kcal / 100 g) × 100 → g.
| Your adult pet’s profile | Dog | Cat |
|---|---|---|
| Neutered / spayed | 1.6 × RER | 1.2 × RER |
| Not neutered / spayed | 1.8 × RER | 1.4 × RER |
| Less active, at a healthy weight | 1.2 × RER | 1.0 × RER |
