The 2026 Cat Data Report.
The companion piece to our dog data report: we ran the same analysis over our 70 cat breed profiles to answer what people actually ask - how long do cats really live, does size shorten feline lives the way it shortens canine ones, and which breeds top the registries. The method is at the bottom, so you can check us.
Cats outlive dogs - comfortably
Averaged across every breed we cover, cats live about 14.2 years to the dogs' 12.2 - roughly 2.0 extra years of companionship. And breed-registry cats are only part of the story: mixed-breed house cats routinely match or beat these figures.
Average of the midpoint of each breed's published lifespan range, same method both species.
Size barely matters for cats
In dogs, size is the single biggest lever on lifespan - our dog report found a gap of over four years between toy and giant breeds. Cats simply do not follow that rule: from the daintiest breeds to Maine Coon territory, average lifespan stays within a year or two. Feline biology spans a much narrower size range, and it shows.
Grouped by the midpoint of each breed's published adult weight (9 / 49 / 12 breeds per group). The flatness is the finding.
Longest- and shortest-lived breeds
The spread is narrower than in dogs but still real: about 7 years separate the top of the table from the bottom. Sturdy shorthair generalists dominate the long-lived end; several bobtailed, rex-coated and hairless breeds sit lower.
Longest-lived
- American Shorthair17.5 yrs
- Russian Blue17.5 yrs
- European Shorthair17.5 yrs
- Brazilian Shorthair17 yrs
- Snowshoe16.5 yrs
- Kurilian Bobtail16.5 yrs
Shortest-lived
- Manx11 yrs
- Japanese Bobtail12 yrs
- Devon Rex12 yrs
- Sphynx12 yrs
- Highlander12.5 yrs
- Singapura13 yrs
Ranked by the midpoint of each breed's published lifespan range. "Shortest-lived" here still means over a decade - cats are generous like that.
The most popular breeds
Popularity follows the Cat Fanciers' Association's 2026 ranking (built on 2025 registrations), in which the Maine Coon is again at number one. Ordinal only: the CFA publishes the order, not exact counts. We profile all ten:
Key takeaways
- Across 70 breeds, the average cat lives about 14.2 years - 2.0 years longer than the average dog breed.
- Unlike dogs, size tells you almost nothing about a cat's lifespan - the weight groups differ by little more than a year.
- Hardy shorthair generalists (American, European, Russian Blue) top the longevity table; Manx, Devon Rex and Sphynx sit lowest - and still average 11-12 years.
- Registry popularity and longevity are unrelated: the CFA top ten spans nearly the full lifespan table.
How we counted, and the limits
The lifespan and size figures come from our own library of 70 cat breed profiles, processed exactly like the dog report: the midpoint of each breed's published lifespan range, the midpoint of the adult weight range (pounds converted to kilograms; where a profile lists males and females separately, the first published range - typically males - is used), grouped into three weight bands. Averages are simple means of those midpoints.
Limits, plainly: midpoints smooth over real within-breed spread; indoor versus outdoor life changes feline lifespan far more than breed does; and our library is a curated set of recognised breeds, not a census of house cats. Treat these as informative patterns, not population statistics. Popularity is sourced from the CFA's most-popular-breeds announcement.
