Pet Age
Convert a dog's or cat's age into a rough human-equivalent age. The first two years count for the most, then each additional year adds a smaller amount. It's a fun approximation, not a veterinary assessment.

Frequently asked
Is 'one year = seven' accurate?
No — the first year of a pet's life is worth about 15 human years, the second another nine, and later years far fewer.
Does breed size matter?
It does in reality (small dogs live longer), but this quick estimate uses a simple dog/cat model.
