If the runner is stopped due to a bug in RunCat ver 9.3, please uncheck "Stop the runner" in preferences.
I apologize for any inconvenience this may cause.

The cat takes up residence in your Mac's menu bar, and he just keeps running!

The cat will run at a speed that depends on the CPU usage on your Mac.
You can see how much the current CPU usage is by looking at the running of the cat.
How about looking at a cat while waiting for a video to be exported or a program to be built?
