Frequently Asked Questions
What does Wash The Cat do?
You route water from tanks through pipes and valves to a shower head. The cat walks toward the shower; keep it under the spray until it is clean enough (about 80 percent) to win the level.
How do I control it?
Everything is click or tap on the canvas. Click red/green valves to open or close taps. Some valves unlock when the cat reaches a marked spot. Use the on-screen restart, pause, sound, and level buttons.
Is progress saved?
Yes. The highest level you cleared is stored in localStorage under ftol:washthecat:lj on this device. CONTINUE on the title screen resumes from that level.
How big is the download?
About ~50 KB of HTML and JavaScript after you press Play. The browser caches it for later visits on the same device.
Does it work on a phone?
The engine uses canvas clicks and scales to your screen. It plays on phones and tablets, though precise valve clicking is easiest with a mouse or stylus.
Is this open source?
Yes. Adapted from WashTheCat by Homer Dilpleu (HomerDilpleu/WashTheCat) under the MIT license. This site build adds noindex on the iframe, namespaces localStorage, and ships LICENSE next to the engine.
