OSRS Boss Pets Guide: Every Pet and Drop Rate
HubIndex page — browse every guide in this category
Boss pets hub for drop rates, grind expectations, and collection-log planning.
Overview: Boss Pets: What We Can and Cannot Tell You
Almost every boss in Old School RuneScape has a pet, and the rates are rare enough that they are a long-term side effect of grinding a boss rather than something you can plan around.
We are not going to list per-pet drop rates on this page. We do not hold verified rate data for every boss, and publishing approximate rates for a chase this long would be worse than publishing nothing — people budget hundreds of hours against these numbers.

Where to Get Verified Pet Rates
What we can give you is the index below: every boss with a guide, so you can find the fight, learn it properly, and let the pet happen while you farm something you actually wanted.
Pets Are a Volume Game
The practical advice is short. Pick a boss you would grind anyway for its drops, get your kills per hour up, and stop counting. Chasing a pet at a boss you dislike is how people end up quitting a grind they were otherwise enjoying.
FAQ
What is the rarest boss pet?
We are not publishing a ranking without verified rates for every entry. The OSRS Wiki lists each pet's rate on the boss's own page.
Does anything increase pet chance?
Kills. Pet rolls are per kill, so kills per hour is the only lever you control.

Bottom Line
97 entries, difficulty 1 to 5.
Start at Brutus (the Cow Boss). The ceiling here is TzKal-Zuk (Inferno).
If you want one thing to go and do after reading this, it is Chambers of Xeric — 6 of the entries here need it, so it unlocks more of this page than any other single requirement.
Each row links to its own guide for mechanics and drops.
Generated from the boss index in src/lib/osrs-bosses.ts (97 entries). Game content changes with updates; verify current details on the Old School RuneScape Wiki.
