Life expectancy, not a generic breed range
Teng et al. created UK companion-cat life tables from VetCompass records. For Sphynx, Table 6 reports life expectancy at age zero of 6.68 years (95% CI 4.53–8.83 years) based on 18 confirmed deaths in the breed category.
This is a UK population estimate. It is not an individual prognosis, a measured healthspan value or evidence that a supplement extends life.

This is a descriptive comparison of the safely mapped PawCosts records from the same source table. It is not a universal breed ranking and does not adjust for individual health, care or confounding.
How long does a Sphynx live in this UK life table?
The recorded measure is 6.68 years. It is specific to this source population, not a countdown for one cat or a measured healthy-life duration.
Living longer is not the only outcome.
The study estimates survival. PawCosts separately treats mobility, cognition and behaviour, body condition, renal and other chronic-care burden as healthspan topics. It does not invent a measured healthy-life duration for Sphynx.
Protect function and notice change early.
Baseline
Track weight, appetite, activity, mobility and behaviour over time.
Prevention
Use veterinarian-guided nutrition and health checks appropriate to the individual cat.
Claims
Do not infer a feline dose or benefit from human, mouse or dog longevity research.
How this profile is governed
Only exact named breed rows from Teng et al. Table 6 are mapped. Crossbred, British cats and Russian cats remain source categories rather than being assigned to a narrower PawCosts breed. No medical review is claimed without a recorded sign-off.
