Pet Simulator 99 Rebirth Guide
Rebirths grant permanent pet power and unlock systems (teleport, extra slots, later worlds). Pets usually stay; area/coin progress can reset depending on the current patch. Only rebirth when you can buy the best early egg and race back through areas in minutes.
Do not rebirth broke
A broke rebirth means crawling Area 1 again for pocket change. Bank coins (community early targets are tens or hundreds of thousands, later millions). If you cannot one-shot Area 1 after, wait.
What it unlocks
Each shrine adds power and a system: teleport, auto hatch, extra pet or egg slots, World 2, mastery, and so on. Extra pet slots are the biggest early DPS jump. Read the live shrine text before you click.
