I use this litter and have for years. Well, the cat uses it, I just buy it. I inadvertently bought the scented version. I initially thought that it didn't smell too bad and maybe since it's so much less expensive I'll keep using it. I dumped it in the plastic tote I keep the litter in and closed the top. Out of the bag, and enclosed, the scent got stronger and stronger. In the enclosed litter box I thought I might be hurting George with the smell, it was so strong. I dumped the litter and I washed his box and the tote and set them in the sun. They both still have that lingering scent. DON'T buy the scented Yesterday's News - DO buy the regular kind. :)
