Same species · two visible copies
Pet Weight & Income Calculator
Compare two copies of one species by weight and displayed income. The result describes this pair only; it does not claim a universal weight formula.
Observed difference
Weight and income are required for both instances.
Weight change—
Income change—
Income per kg · A—
Income per kg · B—
Relative scaling—
Income per kg is a comparison aid, not proof that the game uses a linear formula.
Read the result carefully
If income changes faster than weight, another modifier may be involved—or the game may use a nonlinear weight curve. Match species, mutation, size, pass state, and update before attributing the difference to weight alone.
