I’ve tried Fresh Step Outstretch cat litter, and it really does last longer between full changes. Clumps stay solid and don’t crumble apart. The scent is noticeable but fades after a day. Dust was lower than I expected, which was a plus. My cats didn’t react negatively at all. Combined with feeding Kirkland Signature wet food, the litter box didn’t smell nearly as bad as it used to with cheaper brands.
