Reading a pet weight estimate
This calculator uses a straight-line interpolation between two known anchor weights. Enter the kilogram value for a young pet at age 1, enter the kilogram value for the same pet at age 100, then move the age slider to the point you want to inspect. The output is the estimated weight at that point on the line between those anchors.
Linear interpolation is useful because it is transparent and easy to adjust when better data arrives. It is not a claim that every Grow a Garden pet grows perfectly linearly. If players confirm a curved growth table, event modifier, rarity-specific rule, or mutation-specific weight change, update the anchors or replace this model with the confirmed formula. Until then, treat the number as a practical approximation.
For trade planning, pair this page with the pet value calculator. Estimate the weight here, then use that kilogram value with the closest pet profile and any relevant mutation adjustments. Keep screenshots or recent trade examples when the result will influence a high-value offer, because market demand can move independently from weight math.
