Calcium supplementation for Savannah cats
We have been asked about providing calcium to Savannah cats to balance and work in combination with the raw meat portion of their diet. The considerations and calculations are provided here:
A 20kg animal requires 3,000mg of calcium and 1,500mg of phosphorus.
- 1kg of lean beef contains 100mg Ca and 1,600mg P, so the remaining 2,900mg of Ca has to come from a supplement (for example 7.5g of calcium carbonate or 20g calcium lactate)
Because bone meal contains Phosphorus as well, you can't (in practice) balance the diet with it. The calcium carbonate comes out ahead as a smaller (and cheaper) volume, but the calcium lactate can be given in water which the carbonate can't.
