Calculate Your Cat's Age
Frequently Asked Questions
This is a familiar rule-of-thumb: the first year is about 15 human years, the second brings the total to about 24, and later years add roughly 4 each. It is an approximation for comparison, not a veterinary measurement.
Cats mature much faster in their first two years, so a flat seven-to-one ratio does not fit the usual comparison charts. The human-year result is still only a rough analogy, not a biological equivalence.
AAHA/AAFP life-stage guidance defines senior cats as over 10 years old. Your veterinarian can tailor preventive care to your cat's health and history.
Indoor and outdoor lifestyles involve different risks, and lifespan varies widely by the individual cat. Use this calculator for a rough age comparison and discuss prevention and enrichment with your veterinarian.
