Why cat age charts differ from the seven-year rule
Cats mature very quickly in the first two years, so a flat seven-year rule does not describe early life stages well.
Common cat age model
A common model estimates year one around 15 human years, year two around 24, then adds about four human years per cat year.
How to use the chart idea
Use it to understand life stage and plan conversations with a veterinarian, not as a medical diagnosis.
Quick tips
- Use exact age when known.
- Indoor and outdoor lifestyle can affect aging.
- Ask a vet when age is unknown.
