Description: Protect the Golden Fish with six cats. Learn the wave-10, 20 and 30 bosses, armored and invisible mice, controls and upgrade choices.
Win by keeping robot mice away from the Golden Fish through 30 waves. Cover the route with attacking cats first, add income when safe, and prepare for Rat King bosses on waves 10, 20 and 30. This is temponi123's browser game, not the unrelated Steam title The Whisker Watch.

Step-by-step route
- Open the browser game, choose one of three maps and inspect the enemy path.
- Select a cat in the shop and click or tap grass where its range covers the path.
- Press Space to start; use P to pause and inspect a placed cat's two upgrade paths.
- Steelrats resist weak attacks. Only special cats detect Ghostmice, so check the current ability descriptions.
- Strengthen exposed lanes before bosses on waves 10, 20 and 30, aiming to clear the final wave.
Decision table
| Situation | Action | Purpose |
|---|---|---|
| Opening | Place damage before economy | Prevent early leaks |
| Low coins | Add Catnip Farm after coverage | Fund later upgrades |
| Swarms | Try Fishbone Bomber | Hit groups |
| Fast mice | Try Frost Cat slowing | Buy attack time |
| Distant lanes | Use Sniper Cat range | Reach remote enemies |
| Boss wave | Upgrade before Rat King | Prepare for a spike |
Six cats and upgrades
Yarn Cat tangles enemies with yarn, Laser Cat attacks rapidly, Fishbone Bomber hits groups, Frost Cat slows, Sniper Cat reaches anywhere on the map, and Catnip Farm produces coins. Each of the six cats has two upgrade branches, for 36 upgrades in total.
Troubleshooting
If you lose early, buy damage before more farms. For clusters, try area damage; for fast runners, slowing. The official description does not name the Ghostmouse detectors, so read in-game abilities rather than guessing. Click a cat to upgrade or sell it. Space starts waves or changes speed, P pauses, 1–6 selects cats, and Esc cancels or opens the menu.
Conclusion
The plan: defend the route, grow income carefully, and adapt to armor, invisibility and three boss fights. Cute cats still need to cover the lane.
