PawSense Catproofs Keyboards with Audio Deterrents and Input Filtering

When cats traverse computer keyboards, they can trigger unintended commands, corrupt files, or crash systems. BitBoost Systems addresses this niche but persistent problem with PawSense, a Windows utility that identifies feline keyboard activity and blocks accidental input.

Detection Mechanism

PawSense operates continuously in the background after system boot, monitoring keyboard activity patterns. Its core algorithm analyzes two primary characteristics:

1. Timing Patterns: Cats produce rapid, irregular keypress sequences unlike human typing rhythms
2. Key Combinations: Simultaneous activation of non-adjacent keys suggests paw-sized input

The software typically detects feline presence within 1-2 keystrokes. According to BitBoost's documentation, the system avoids conventional machine learning approaches in favor of deterministic pattern rules, reducing false positives during human typing.

Response Protocol

Upon detection:

1. An ultrasonic deterrent sound plays (inaudible to most humans)
2. Keyboard input is temporarily blocked
3. Visual indicators appear onscreen

The audible feedback aims to condition cats to avoid keyboards through negative reinforcement. The software includes a screensaver mode with enhanced detection sensitivity and a quick-disable hotkey for emergencies.

Platform Support and Limitations

Currently supported on Windows 2000 through Windows 10, though no macOS or Linux versions exist. Key constraints include:

• Effectiveness depends on speaker volume for auditory training
• Requires manual configuration for specialized keyboards
• Cannot prevent physical damage to hardware
• No mobile device support

The official FAQ addresses common setup questions, while the main product page details purchasing options. At $29.95, it occupies a specialized niche between physical keyboard covers and comprehensive user monitoring solutions.

Practical Alternatives

For those seeking non-software solutions:

• Keyboard trays with sliding covers
• Infrared motion sensors triggering alarms
• Training mats emitting mild static pulses
• Simple towel coverage when unattended

While PawSense won't replace enterprise security tools, its focused approach to accidental input prevention demonstrates how specialized utilities can solve unusual computing problems. The software's endurance since 1999 suggests persistent demand from cat owners working with critical systems.
