A number needs a description
Cats Protection reports an average life expectancy of 11.7 years for pet cats in the UK, citing published research. Blue Cross gives a general average of around 12 years and notes that some cats live to 20 or beyond. These statements are not a timer for an individual cat. Their wording and context matter more than pretending the decimals form a personal forecast.

Age is not a verdict
Both guides discuss life stages, individual differences and the relevance of care. A stage label can organize a general article but cannot establish health, comfort, future lifespan or a reason for a care decision. This site does not estimate years remaining from breed, sex, weight, neuter status or lifestyle. It does not add and subtract population associations to make an individual promise.

Start with a better reading habit
The number passport keeps a statistic beside its scope and limit. The stage notes compare source definitions, including a difference in the kitten/junior boundary. Neither tool assesses an animal. If your reason for reading is an actual health, welfare or end-of-life concern, seek appropriate professional support without waiting for a worksheet or app answer.
