Cat litter statistics we are comfortable citing
This page is deliberately narrower than the old version. We removed weakly sourced market-share claims and kept the public data points that are most useful for litter odor discussions.

Canadian Cat Ownership
These are the strongest public data points we found for understanding the size of the cat-owning audience in Canada.
Households with cats
About 38%
CAHI regularly reports cats as one of the most common household pets in Canada.
Canadian Animal Health Institute →Pet cats in Canada
About 8.5 million
Useful as an audience-size reference for litter and odor-control research.
Canadian Animal Health Institute →Housing Pressure and Small-Space Living
Litter odor is usually harder to ignore in apartments, condos, and tightly sealed winter homes, so housing context matters.
Apartment living remains common in major metros
High relevance
Statistics Canada and CMHC both track rental and apartment conditions that shape how indoor odor spreads in smaller homes.
Statistics Canada →Rental affordability remains a pressure point
Shared national trend
CMHC rental reporting helps explain why many cat owners need odor control that works in smaller spaces without constant litter replacement.
Canada Mortgage and Housing Corporation →Why Odor Control Advice Focuses on Ammonia
Public health and adsorption literature are clearer on ammonia exposure and odor-trapping mechanisms than on brand-level litter performance claims.
Ammonia is the odor to watch
Primary litter-box concern
NIOSH identifies ammonia as an irritant, which is why litter-box smell discussions usually center on ammonia management.
CDC / NIOSH →Activated carbon is used for gas adsorption
Well documented
Peer-reviewed adsorption research supports using activated carbon where gaseous compounds need to be trapped instead of merely masked.
Environmental Science & Technology →What we intentionally removed
- Brand-level satisfaction and guarantee claims that we could not verify independently.
- Fine-grained litter market-share numbers without a strong public source trail.
- City rankings that looked precise but were mostly assembled from mixed survey material.
Need a product example after reading the data?
We use Purrify as the current example of an activated carbon additive because it matches the product type discussed across the site.
