For those who don't like to clean the litter box after their cats. This magical tray will do everything itself, you just need to change the bags and add filler. Nothing spills out, there are no odors. After an adult cat goes to the toilet, the program starts. The volume of the garbage container is large.  The application is very accessible. Every step is spelled out. I see how long the cat was there, how the cleaning is carried out, how the air neutralizer works. In general, everything is very cool. We and especially the cat liked it! The main advantages are the price, which saves time and sand costs, the cat quickly got used to the tray, the dimensions are ideal. I recommend!!!
