Arm & Hammer Ultra Last Cat Litter Review

Last Updated by Brandon F. on May 6, 2020

Advertised Product Description

This is our Arm & Hammer Ultra Last Cat Litter Review.  Arm & Hammer Ultra Last cat litter stresses that it is extremely long-lasting and will keep your household smelling fresh for days.  This is accomplished with special granules that are coated in Arm & Hammer baking soda as well as powerful odor destroyers.  This product is available in several sizes including 20, 26.3, 31, 37, 40, and 50-pound boxes.

Who This Cat Litter is Intended For

This cat litter is designed for those who put long-lasting odor control over every other factor.  Particularly, it is intended for those who may go on long business trips or vacations or that have busy work schedules that don’t allow them to constantly maintain a litter box but still want the odor in check.  It is typically meant for single-cat boxes and for owners who are willing to spend a little bit extra for something that works.

What Makes This Cat Litter Unique

This litter is special in its approach in that it prioritizes controlling odors, and doing so for long periods.  While doing this, it still attempts to not take shortcuts in other important factors such as clumping ability or messiness.  Controlling odors for long periods can be one of the biggest challenges for a litter so it is impressive to have a particular product build its entire slogan around that.

Clumping Ability – 4 star

Overall this litter clumps decently.  The clumps harden relatively quickly and are small and solid, which makes cleanup and general maintenance easy.  Any clumping issues that do exist (of which there are few) rest completely in its ability to harden feces and urine in the box, so problems related to caking on cat paws or the side of the box aren’t a concern.

The only time this might become a burden is in a particularly busy litter box where a lot of cats are constantly moving around the litter.  In this case, you might have to be a bit more concerned with caking due to failed clumps.  To overcome this, you will have to be more timely on cleaning and maintaining your cat’s litter box.

Scent – 1.5 star

Unfortunately, the scent is a major issue with this litter.  The smell of the litter itself is, simply put, awful.  It is extremely powerful and artificial, and both cats and humans alike have shown disapproval.  If you or your cat(s) have a sensitive smelling ability or allergies then issues may arise by using this product.

The cat waste smells are, for the most part, covered up by the baking soda, but many people have said they honestly would prefer the smell of cat feces and urine over the smell of this litter!  Do your due diligence with this product before purchasing a large box and see if you and your cat can handle the litter scent.

Messiness – 3 star

For the most part, this litter is pretty clean.  There are some minor dusting issues but nothing out of the ordinary for a clay-based litter.  Caking isn’t a concern and the litter is heavy enough to not be easily transported or kicked out of the box by your cats.  As mentioned above, when you introduce multiple cats into the mix this might no longer be the case but this litter isn’t targeted at multi-cat boxes.

This litter price falls in the mid to premium-priced range.  This is a bit higher than most of the other clay-based litters on the market which we were disappointed to see.  This is particularly true seeing how there are some glaring issues associated with the scent that this litter puts out.

Overall Rating – 3 star

The Arm & Hammer Ultra Last Cat Litter Review earns 3 out of 5 cats.  A well-performing product with good clumping and little caking issues, and it does for the most part stand by its promise of being a long-lasting odor blocker.  But the litter smell is bad enough that you might overlook its many positives on this one negative alone.  If you can handle the scent or decide to wear a gas mask around the litter (might need one for your cat as well) then it isn’t a terrible deal, especially if you can find it on sale.
