My kitty has an odorless kitty box. Seriously. Have had cats my whole life and stumbeled on this about 15 yrs ago. Its a cadboard looking tray made out of recycled paper.fillit 1/4" to 1/2 full no odor. Zoey gets a new box every month. We scoop and every two weeks gets all new litter. The worst thing you can do is plastic.. makes a big stink. This recy led box NO plastic liners.
Even zoey loves it.
