The best cat litter for odor control is a litter that doesn’t necessarily replace the odor with a perfume but nevertheless masks the odor of cat litter. The odor can be masked by adding an artificial fragrance or by neutralizing the odor.

The cat litters we have reviewed are mainly litters where the odor is neutralized using different methods. We have also chosen one lightly fragranced product primarily because the perfume used is subtle and not overly fragranced.

Some Of The Best Odor Control Cat Litters Are:

1. Fresh Step Advanced Uses Activated Charcoal
2. Dr Elsey’s Ultra Premium Cat Controls Odor Naturally
3. Arm And Hammer Platinum Clump And Seal Uses Plant Derived Particles
4. Fresh Step Multi Cat Advanced/Febreeze Added Fragrance
5. Purina Tidy Cats Scented Litter/Fresh ScentAmmonia Blocker & Added Fragrance
6. Nature’s Miracle Intense Defense Fragrance Free And Bio Enzymatic Odor Control

There is nothing worse than coming home to a less than pleasant odor from the cat litter. Because our pets do spend time inside with us, it is normal and to be expected that there may be some less than desirable odors. We can work around this.

FAQ For Cat Litter Odor

Why Does My Cat’s Urine Smell Like Ammonia?

Cat urine smells like ammonia because cat urine contains urea. Urea is a waste product of protein breakdown. Cats are big protein eaters. Bacteria breaks down the urea and this is what releases ammonia and the along with it the strong smell that is often associated with cat litter.

You could try feeding your cat a different source of protein to see if that makes a difference.

To help combat the ammonia smell, litter needs to be changed frequently. If the ammonia smell if very strong or has changed and is now noticeably stronger than usual see your vet for advice.

The only way to really get rid of the ammonia smell is to use an enzyme cleaner to remove cat’s urine.
