🐱 Cat Age to Human Years Calculator

This tool uses a typical feline curve:

• First year ≈ 15 human years.
• Second year adds ≈ 9 human years (so a 2‑year‑old cat ≈ 24 human years).
• Each year after adds ≈ 4 human years.

Real aging depends on genetics, indoor vs. outdoor life, diet, and vet care. Use this as a guideline, not an exact conversion.
