Pet tier list
Tier list weighs both trade desirability and how usable a pet is for current rebirth grinds.
Reading the PS99 tier list
Pet Sim 99's tier list shifts faster than other games on this site because new Huges land in every major content patch and the developer regularly tweaks pet damage values. The ordering here reflects the patch noted at the top — older snapshots will be inaccurate for newer content.
Titanics are the small top tier — usually 2–3 of them — and they're effectively above the rest of the game in trade weight. Below them sit exclusive Huges, then current-meta farmable Huges, then earlier-generation Huges that have lost some shine.
How to use it for grinding
- If you're chasing damage per second, focus on S-tier pets — their multipliers are usually orders of magnitude higher.
- If you're chasing trades, the same S tier holds — Titanic Storm Agony, Titanic Cat, Huge Pixel Cat are top-of-market.
- Don't waste rebirths trying to optimize around B-tier pets if A-tier ones are accessible to you.
Why these values carry a date (status: August 16, 2026)
This page deserves its caveat up front, stated plainly: the public trackers our PS99 cross-check relied on have gone dark — as of our August 16 audit, the two primary sources return errors rather than lists. The values behind this tier ordering were last two-source verified in May 2026, and rather than silently pretend otherwise, every PS99 surface on this site carries that date. We chose retention over deletion because the ordering of long-standing top pets (Huge and Titanic tiers especially) historically moves slowly — but a dated number is a weaker number, and big trades deserve wider margins than usual while sources are down.
One trap we specifically avoided, and you should too: when re-checking a PS99 value by searching, the top results that "confirm" a number can be pages that copied it — sometimes ours. Circular confirmation is how stale values calcify across every tracker at once. Until a live independent source returns, treat this list as structure rather than price: the Huge-hunting math and the Huge-vs-Titanic breakdown hold regardless of exact numbers, and the codes reality-check is evergreen. When our sources come back, this block will say so — with the date.
