Query: Does not do the job!

My kitty is not really much of a scratcher/digger when it comes to his box but these liners must be paper thin. Kitty scratches right through them and in order to remove the bag from the box I need to place it in another liner or my floor will be full of used litter. Not very cost effective. Regular trash bags work better and are cheaper.
