Explanation

Kittens use energy for maintenance and growth. The result is a general starting estimate for healthy growing kittens, not a fixed ration throughout kittenhood.

Formula and methodology

Weight is converted to kilograms and RER = 70 × weight in kg^0.75. The healthy-kitten estimate is 2.5 × RER.

Worked example

A 2 kg kitten has an RER of about 118 kcal/day. Multiplying by 2.5 gives an estimated 294 kcal/day starting point.

Assumptions and limitations

Growth requirements change with age, activity, body condition, environment, neuter timing, and health. Use nutritionally complete kitten food guidance and regular veterinary review. This calculator is not suitable for a kitten with illness or poor growth.## Methodology references

No. It is the selected healthy growing-kitten factor.

How often should intake be reviewed?

Review it as the kitten grows and whenever weight, body condition, health, or appetite changes.

Does this choose a kitten food?

No. It estimates energy and does not recommend brands or formulations.
