Veterinary Energy Calculator for Dogs and Cats
Calculate daily energy requirements for dogs and cats using RER and maintenance factors. This tool also builds feeding plans for weight loss and hospitalized patients.

Safety checks
- Calculation basis: this tool converts entered weight, species, mode, and optional food density into a structured starting feeding estimate.
- Scope: it helps with calorie arithmetic and progression planning. It does not choose the therapeutic diet, disease-specific target, or final medical nutrition strategy.
- Before acting: compare the estimate with body condition, hydration status, current intake, and the patient’s response over time.
- Hospitalized patients: reassess tolerance, electrolytes, and clinical trajectory rather than treating the progression output as an autopilot protocol.
Basis and limits
RER formula: RER = 70 × (body weight in kg)^0.75
RER is the baseline energy requirement used to estimate caloric needs in dogs and cats. Maintenance and clinical conditions adjust this value.
