Cat Age Calculator
Convert cat age to human years.
How to Do It Manually
Cat ages are similar to dogs but slightly different: first year ≈ 15 human years, second ≈ 10, then ≈ 4 per year.
Cat Age (human equivalent) ≈ 15 + 10 + (4 × years after 2)
- If cat < 1 year: multiply by 15.
- If 1–2 years: add 15 + (10 × (age − 1)).
- If > 2 years: add 15 + 10 + (4 × (age − 2)).
