We settled on Arm & Hammer for our cat. It's middle-of-the-pack litter that works great, has good reviews, and comes in just a box, no liner. Nothing fancy like crystals, nor is it some bougie premium litter like Boxiecat.
But then again I'm in Canada and some provinces here still get milk in bags -- so we're weird like that.
I think some brands of clay litter come out used to come in plastic tote thingies. I know this because there was a popular how-to for frugal people to make them into panniers for your bike 😅
