Kittens that weight 3.31 pounds or more can safely use PAWBBY Box in automatic mode. It is not recommended to use the pawbby self-cleaning litter box if your kitten does not meet this minimum weight. When you see your kitten has used PAWBBY Box, turn it on, and PAWBBY Box will automatically perform a clean cycle. Once it finishes, turn the power off. This way, your kitten is safe while they get accustomed to PAWBBY Box at a young age, and you don’t have to scoop the litter box!
