Something has definitely changed, and it's not for the better.
I have tried several 'good' brands of litter for my 4 cats, but always come back to this one. It used to be excellent, so didn't mind the price of it, but for the past few months I've noticed it's a lower grade of product. They've changed the formula, and now it's just a standard litter as the cheaper ones. I continue to use it because I like how easy it is to sift, but it's definitely reduced in quality. It's very disappointing.
