The scope of the statistic
Cats Protection’s 11.7-year figure refers to pet cats in the UK as summarized from research. Blue Cross uses a rounded general figure of about 12. Neither sentence gives this website an individual survival model. Reporting a source statistic honestly means keeping the location and wording, not presenting the number as a universal expectation for every cat everywhere.

A tempting calculation to reject
If a fictional cat is older than a reported average, it does not follow that it has exceeded a personal allowance or has a negative number of years left. Subtraction is easy; the interpretation is wrong. This website therefore does not include a remaining-life calculator. A population summary and an individual’s current welfare are different questions.

Precision is not personalization
The extra decimal in 11.7 does not make that statistic more suitable for a specific cat than a rounded educational summary. A reader still needs to know what is being summarized and for whom. We do not manufacture confidence intervals, breed predictions or risk-adjusted scores from two general articles. The number passport keeps the contextual sentence attached instead.
