I had tried everything! The regular litter boxes were becoming too much! they were too messy, stinky, and my new dog was drawn to them! I tried litter kwitter and it worked for a while but then my car kept getting lazy, and using the floor and tub too! It was horrible! I saw these commercials and I thought that I should give this a try. It's been the best thing since! It is a little pricey, but its well worth the investment! Its easy to use, my cat loves it, and I save time and money every month!
