Clay clumping workhorse — buy what your cat already accepts before “upgrading”
Litter brand loyalty is mostly the cat's. Fresh Step is a common clay clumper with broad Amazon availability. Switch gradually if you change formulas — abrupt swaps cause boycotts. Scoop daily; “odor control” marketing does not replace scooping.
Who it's for: Most multi-box homes that want reliable clay clumping.
Skip if: You need lightweight or silica crystal specifically — different litter class.
Alternatives with different tradeoffs — not clones of the same pitch.
