NoPeeNow, A Pet Behavior Adjustment Device that stops the cats to pee around in your home

I was so bothered by my kitty that she likes to pee on my bed, I checked everything she needs and I also took her to the vet. After I troubleshot everything I can think and listen to the doctor’s word, I realize she just has some bad behavior. So that’s why I decide to make some device to help to adjust her behavior and make my life easier.
