🎂 Pet Age Converter
See how old your pet is in human-equivalent years — across cats, dogs by size, rabbits, ferrets, parrots, and tortoises — with the matching life stage.
🎂 Human-equivalent age
An approximate model — ageing rates vary widely by species, size, and individual. Use it as a rough guide and discuss life-stage care with your exotic vet.
Age is a curve, not a multiplier
The old “multiply by seven” rule fails because most pets mature very quickly in their first two years and then age more gently — and the exotic world stretches that even further, from ferrets that pack a lifetime into under a decade to tortoises that outlive their keepers.
Knowing the life stage helps you time the right care: growth diets and socialisation early, then health screening and comfort adjustments as an animal enters its senior years.
❓ Frequently Asked Questions
Why is there a different model for each species?
Animals mature and age at very different rates. A cat reaches roughly 15 human-equivalent years by its first birthday and 24 by its second, then adds about four a year. Dogs age faster the larger they are, while long-lived species like parrots and tortoises accrue human-equivalent years far more slowly. Each species here uses its own curve.
How does the dog size setting change the result?
After age two, larger dogs age more quickly. This tool adds roughly four human-equivalent years per dog year for small breeds, five for medium, six for large, and seven for giant breeds — so a five-year-old giant breed reads considerably older than a small one of the same age.
How accurate are the numbers?
They are approximate general estimates. Real ageing depends on genetics, diet, husbandry, and the specific (sub)species, and the exotic figures in particular are simplified models — treat them as a rough guide, not a precise readout.
What should I do with the life-stage label?
Use it as a prompt to review life-stage-appropriate care — diet, enrichment, and health screening all change from baby to senior. Confirm what your individual animal needs with a qualified exotic or wildlife veterinarian.
