Ha, me, too, Inkii. I thought it was a Very bold move on Weaver's part to talk about boosting puppy litter sales in a pet store.
When my parents bought litter for our old cat, selection was based on availability (ie Costco) and price. Not much thought process put into it. Odor control and clumping didn't come too much into play. For most of his life, I think we used FreshStep and Arm & Hammer.
When I took care of my grandparents' kittens, I went for the cheap natural clay products from BigLots and Costco. Main factor: price and clumping. Odor control was not big since I cleaned it so much. Availability wasn't an issue because I only had them a couple months.
With this years' foster kittens, I kind of went overboard on making sure they had a good start, so I actually did some reading on the "best litters." When I moved them to commercial litter (from hogsfuel), I happened to get what would become my favorite--Country Cat wheatgrass litter. It was small enough to sift, it was affordable, it smelled good but was unscented, natural and environmentally scented, no dust, and best yet, it absorbed/degraded when wet and stuck to poop. The latter made cleaning easy--no mess for scooping poop out and all I had to do for the moist litter was scoot/scrape the top intact layer of litter off to the side and scoop the bottom degrade layer out. I could change the litter less often so the bag went further.
Compared to
YesterdaysNews: Hated it. Super wasteful, wouldn't sift. Absorption and clumping were not effective. Messy.
WorldsBest: Cats didn't like it, clumped but didn't absorb well, so wasteful and had to change out the whole pan of litter with every cleaning. Stank and was messy.
I think I tried one more, but I can't remember what it was. My fav was still the Cat Country, and I would use it again for future cats.
ETA--I should say that some litters are advertised as flushable--this wasn't a big perk for me. I flushed solid waste a couple times, but for the most part didn't.
