Daily energy and portion sizes for every life stage, without the mental arithmetic.
Weight bands, age limits and safety checks, read straight from the product label data.
Branded, plain-language instructions the owner can actually follow at home.
How it works
Every calculator follows the same order, so staff build muscle memory across food, dosing and weight tools. Results update as you type. There is no Calculate button.
Pick the unit
Kilograms or pounds. Switching converts the number, it never clears what you typed.
Enter the patient
Weight, species and life stage. Only the fields this calculation actually needs.
Read the answer
The figure updates live, rounded to something a person can measure, with the formula shown underneath.
Hand over the printout
One click prints the branded handout, or saves it as a PDF to email later.
