This is the definitive Pet Simulator 99 best pets tier list for May 2026. After the Titan Garden and Dimension Update, the meta has shifted toward Titan-class pets and mutation stacking. Diamonds-per-second (DPS) is the only number that matters at endgame.
S-tier pets push you past the late-game walls. D-tier pets are nostalgia bait — sell them.
