How to Play Wash The Cat - Step by Step
The Wash The Cat page loads a ~50 KB pipe puzzle in an iframe. Route water to the shower and clean the cat. Press Play on this page to start.
Step 1 - press Play on this page
Press Play to inject the iframe (~50 KB). The title screen loads inside the canvas. Upstream is HomerDilpleu/WashTheCat (MIT, JS13K 2025).
Step 2 - start the game inside the canvas
On the title screen, drag the small green ball over the hidden letters until the PLAY button appears, then click PLAY (or CONTINUE if you have saved progress).
Step 3 - open and close valves
Click red/green valve handles to let water flow between tanks. Pipes carry water only when both ends are open. Watch tank fill levels before the cat reaches the shower.
Step 4 - use position valves
Later levels add valves that open only when the cat stands in a marked zone. Move the cat by controlling where the shower spray hits it.
Step 5 - finish and unlock levels
Clear a level with at least ~80 percent cleanliness to unlock the next. Progress saves to ftol:washthecat:lj in your browser. Use restart or the level picker at the bottom.

- No install, no sign-up. Open a tool and get a working output in seconds - nothing to download and no account to create. Tools that need heavy processing run it on our service, so even a low-powered machine gets the job done.
- Analytics stops at the page view. We measure which pages get visited, not what you type or upload inside a tool. There is nothing to sign in to and no profile is attached to your input.
- Open-source core components. The processing engines underneath (libheif, libde265, pdf-lib, terser, clean-css, ffmpeg.wasm, and others) are public and audit-able. We link to each one in its tool page's footer.
- Free, with or without ads. All tools are fully functional without sign-up. The Disable Ads button in the header is always available if you need a distraction-free run.
