The short version loses something
Cats Protection’s average figure comes with a UK pet-cat research context. A caption saying cats live 11.7 years leaves that context behind and can sound like an individual deadline. Blue Cross’s rounded average also sits beside a statement that some cats live much longer. The number passport restores those surrounding words instead of making the number bigger or more dramatic.

The next temptation is personalization
A fictional reader might subtract a cat’s age from the figure and call the difference time left. Nothing in the two source summaries supports that conclusion. An actual cat’s current welfare cannot be read from the arithmetic. This is why the site rejects a remaining-life calculator even though it would be easy to build and might look persuasive.

A more useful ending
An honest article can help a reader ask what population a number describes, which guide defines a stage and what remains unknown. It can also stop short of an individual prediction. If the real question concerns health, comfort or a difficult care decision, appropriate professional support is the useful next step. More decimal places or another app reply should not delay it.
