The Two Types of Odor Control
If you live in a small apartment, you can't afford cheap litter. The smell permeates everything—your clothes, your sofa, your bed.
You need a litter with Activated Carbon or probiotics. Baking soda alone often isn't enough for multi-cat homes.
The "Nose Blindness" Danger
You might get used to the smell ("nose blind"), but your guests certainly aren't.
💡 Pro Tip: The "Nuclear" Option
Most cheap "odor control" litters just use heavy chemicals that are bad for your cat's lungs.
The Better Way: Use an unscented litter and add Purrify Deodorizer.
Purrify uses enzymes to essentially "eat" the waste at a microscopic level. It kills the source of the smell instead of just spraying perfume on it.
Carbon vs. Baking Soda vs. Probiotics
Baking Soda: Cheap, absorbs some smell, but mostly filler.
Activated Carbon: Very effective at trapping gas molecules. Look for this in premium clays.
Probiotics: The new gold standard. Active bacteria that hunt down and destroy odor-causing waste.
Frequently Asked Questions
Why does my litter box still smell after scooping?
Small crumbles of poop or urine-saturated clay are often left behind. These bacterial colonies grow and emit gas. Using a better clumping litter (like Dr. Elsey's) or adding a probiotic (like Purrify) helps prevent this. Learn more about how <PurrifyLink variant="inline">Purrify</PurrifyLink> works.
Is better to cover odor or remove it?
Always remove it. Covering odor with floral scents just creates a 'poop-pourri' smell that is actually more offensive to sensitive noses.
