Pawsense is a software program that can save your computer from your cat’s evil plot to destroy your computer. Pawsense detects and blocks cat typing and, also when it senses that a cat is on the keyboard, Pawsense makes a sound that will annoy the cat (a harmonica sound, a hissing sound or you can even record a sound that you think will deter your cat — maybe a dog barking?), so the cat will leave the keyboard. Pawsense currently works only on Windows. Stop your cat’s plan to conquer the world. We know it’s happened to many readers. I’d buy stock in this company if I could.
