How this tier list works
PS99 pets are ranked by damage multiplier + farm efficiency + trade rarity. Higher tier pets clear biomes faster and hold trade value during the inevitable next-update meta shift.
Rarity ladder: Common → Uncommon → Rare → Epic → Legendary → Mythical → Huge → Titanic → Exclusive
Most tier conversations focus on Huge / Titanic / Exclusive since those produce 1000×+ damage multipliers vs Mythicals’ 100× range.
S-tier breakdown
Huge Hacked Cat is the May 2026 meta defining pet — released during the May 2026 “Cyber Update”, its glitch-themed visual + top multiplier put it at the top of trade requests within 48 hours of drop.
Huge Empyrean Agony + Huge Genie Cat trail Hacked Cat by ~15% damage but have lower active supply — making them stable long-term trade holds.
How to progress through tiers
- Open eggs in current zone until you hit Mythicals
- Hatch repeatedly to unlock biome progression
- Once you have Huge of any kind → trade up for current meta Huge (consult community trading hubs)
- Save Exclusives — they hold value across multiple update cycles
Updated meta notes (May 2026)
- Cyber Update shifted entire tier list — Hacked Cat new #1
- Anniversary 2025 pets (Empyrean Agony, Genie Cat) holding A-S despite age
- Pterodactyl supply too high after Easter Egg rotation — likely C/D tier rest of year
