Why Does Pet Weight Matter?
Pet weight changes how well your pet performs. Heavier pets lower your ability cooldowns. For example, a cooldown can drop from 10 minutes to 1 minute. Heavy pets are also much larger on your screen. They are very rare to hatch, so they are worth a lot more in the trading economy.
Frequently Asked Questions (FAQ)
How can the tool calculate max weight at age 100 if my pet is only age 2?
The tool uses the game's linear growth formula. Every year, a pet gains exactly 10% of its base weight. The calculator reverses your current stats to find the start weight, then projects it forward to find your max weight.
Why does my pet's tier look wrong if the weight is off by just 0.01 kg?
The game rounds decimals on your screen to keep the screen clean, but the calculator uses exact math. If your pet is right on the edge of a new size classification, a tiny 0.01 kg display rounding difference can shift the tier display.
Does using an Ostrich pet mess up the weight calculation results?
No. The Ostrich pet gives extra age at hatch, but it does not change the core hatch weight. The growth formula stays the same, so the tool remains perfectly accurate.
