I don't know. I've used this litter for a very, very long time and was completely satisfied. I also wrote letters on their behalf when Costco here changed to another product, and was elated when we got the Litter Purrfect back. But this is bad...seriously. I asked a friend who also uses it and she said yes, it is dustier than in the past. I have also noticed that it isn't every container. Some seem to be normal. But...the ones that are dusty are flat out horrible. It's like driving a pickup down a dirt road at 50 mph.
