I have had this for many months hoping to get more time to fill.  I have one cat.  I love the roll and perforation and wanted that for years.  Mentally suggested it and glad you heard me.  I am very disappointed with it claiming to hold up to 6 months of litter. First, who would want that?  Secondly this fails to close and seal the odor as the original Litter Genie did.  I have to change this weekly.  Improvements still needed for this to become a good item.  Hoping for better with the next gen.
