A watercolor pond: a small pause on your desktop.

A little cat, a watercolor koi pond, and a quiet corner of your desktop. Enjoy Wallpaper Cat alongside work, study, or a break.

Small things worth noticing

Your desktop can have its own weather.

01

Breathe inside the wallpaper

A watercolor pond settles behind your icons, with willow shade along their side. Displays share fish and ripples. Turn off Enhanced effects, pause the pond, or enable launch at login, which is off by default.

02

Watch the cat go fishing

The cat hops onto its fishing stone, fixes on a koi, crouches, and strikes. It eats one only when four or more koi remain; otherwise it catches one to play and lets it go.

03

Let day turn into night

Choose sun, clouds, rain, or snow yourself. Keep a fixed day or night, or switch automatically with your computer’s local time. No location lookup or live weather service is needed.

04

Play your own music

Built-in guqin, singing bowl, wind chime, and pond-water loops play locally, and you can import music from your computer. Play in order, shuffle, or repeat one track, with one soundtrack across your displays.

05

Give the kitten a name

After eight hours of accumulated running time, receive your first rename card automatically. From the next month, get one card per month, valid that month without stacking. Names can be up to 12 characters.

06

Keep your own koi

Start with four koi and add up to 50. Name them, choose a pattern or paint your own. Food drops are unlimited; koi grow from what they actually eat that day, and today’s ranking refreshes at local midnight.
