Dr. Elsey's Ultra Unscented Clumping Clay Cat Litter vs Dr. Elsey's Ultra Unscented Clumping Clay Cat Litter

Both are in our cat supplies picks, which means neither is a bad choice. What follows is what actually separates them, and who each one suits.

Dr. Elsey's Ultra Unscented Clumping Clay Cat Litter, 18 lb

Dr. Elsey's Ultra Unscented Clumping Clay Cat Litter, 40 lb

Why it is on the list

The smaller bag of the same litter โ€” worth starting here before committing to 40 lb, in case your cat objects.

Unscented and hard-clumping. Cats reject perfumed litter far more often than owners expect.

Choosing between them

Your cat has started avoiding the tray

Dr. Elsey's Ultra Unscented, and start with the 18lb bag rather than the 40. Unscented and hard-clumping, which removes the two most common objections at once. Introduce it gradually mixed with the existing litter rather than swapping in one go.

You have settled on a litter and want it cheaper

The 40lb Dr. Elsey's. Same litter, better price per pound, and worth buying only once you know the cat accepts it. It is heavy โ€” consider where you will store it before ordering.

Several cats share a tray

ARM and HAMMER Clump and Seal SLIDE. The non-stick property is the actual feature: clumps release from the tray bottom instead of cementing there, which is where the unpleasant part of the job lives and where a multi-cat tray gets worst fastest.

You want something lighter to carry

Cat's Best, which is plant fibre rather than clay. Noticeably lighter for the same coverage and it still clumps properly. The caveat is texture: it feels different underfoot, and a cat with strong preferences may object, so transition gradually.

What people get wrong

  • Buying scented litter. It solves your problem and creates the cat's, and it is the most common reason a cat stops using the tray.
  • Switching brands overnight. Mix the new into the old across a week or two, or you risk breaking a habit that was working.
  • Buying the large bag first. A rejected 40lb bag is expensive, heavy and hard to return.
  • Reading tray avoidance as behaviour rather than a message. It is usually the litter, the location or the cleanliness โ€” and occasionally a medical problem worth a vet visit.
  • Cleaning the tray with strong-smelling products. Residual scent puts cats off as reliably as scented litter does.
