RunCat

RunCat is a simple and fun way to monitor your computer's CPU usage. The running cat animation indicates the CPU speed so you can instantly see how hard your computer is working. If the cat is slow, the CPU is underutilized. If the cat is fast, the CPU is busy.

RunCat is also a great way to learn more about how the CPU works. You can track the cat's speed over time and see how CPU usage changes with different activities. You can also use RunCat to identify the applications that use the most CPU.
