How to Find Urine
Use the UV light feature to find hidden pee stains
Turn the lights off so it's fairly dark.
Turn on UV light mode (the blue light).
Shine the UV light about 3 feet from surfaces that you suspect have urine stains. Dried urine will glow. Note: other stains might also glow.
Red Cat Laser: use this to play with your cats! Try keeping it just out of reach. If your cat "catches" it too often, they may lose interest. Avoid shining into the eyes of cats or people.
White safety light: this mode is very useful in the case of power failure, or as a general flashlight. In this mode, a full AA battery will last about 2 hours.
