PawSense is software that detects and blocks cat-like typing

Here’s how the program works. Every time your computer boots up, PawSense automatically starts up in the background to watch over your computer system and monitor keyboard activity. When PawSense detects a cat (usually “within one or two pawsteps”), it triggers a popup window that locks the keyboard, preventing the animal from wreaking havoc on one’s operating system.
