Bongo Cat Collection Tracker
Mark the hats and skins you already own, filter the gaps, and keep a private checklist that stays in this browser.
Mark your Bongo Cat collection
Tap a row to mark it collected. Use Missing only before a chest session, or select Limited / retired to see items that cannot be treated like standard drops.

What belongs in a Bongo Cat collection
The standard chest pool is only one part of the collection. Steam publishes its rarity chances as Common 90%, Uncommon 9.5%, Rare 0.49%, and Epic 0.01%, while the site records Legendary as about 1 in 500,000. Those figures describe rarity, not the probability of a particular named item.
Event and paid items need a different label. The official June 2026 Summer Event announcement said it had 20 exclusive items and that they would stop dropping after July 14. Steam also lists paid cosmetic DLC packs. A completion checklist that flattens those into chest loot would make planning less honest, so the tracker separates them.
What this tool stores, and what it does not claim
Your item marks are stored with local browser storage. They are not uploaded, shared, or matched to Steam. Clearing browser data can remove them, so use the clear button only when you intend to reset.
For live market listings, use the Steam Community Market. For whether a duplicate is worth turning into a higher-tier random item, open the trade-up planner; for the full catalogue sorted by scarcity, use the value list.
Collection tracker FAQ
Does this Bongo Cat collection tracker connect to Steam?
No. It cannot read your Steam inventory or account. Marks are saved only in this browser, so you can use it without signing in or sharing inventory data.
Why does the tracker include event and DLC items?
A collection is more useful when it separates standard chest items from retired event rewards and paid DLC. The filters make that distinction visible instead of pretending every item can be earned from the same chest.
Can I complete every item through normal chest drops?
No. Steam says standard chest drops use the published rarity table, but some items came from limited events, DLC, or special windows. This tracker labels those availability differences rather than assigning invented drop odds.
