These garbage bags can also be used with the automatic cat litter box, petsnowy. Please refer to the 3rd and 4th images for instructions on how to use them. As it gets hotter, these are cost-effective for frequent changes! For those who are hesitant about 60 sheets from the start, we are selling an "Trial 5-sheet" pack! Please try the trial pack first, and then you can purchase the 60-sheet set, or you can start with the 60-sheet set right away. I use them for my own cats, so I think you can use them without any problems! I also use them for my cats, and they work without any problems.
