Pet Age Calculator
Convert your pet's age to human years for dogs, cats, rabbits, hamsters, horses, and parrots. Select your pet's species, enter their age, and instantly see their human-equivalent age.
How Pet Age Conversion Works
Different animals age at vastly different rates. A 2-year-old cat is roughly 24 in human years, while a 2-year-old hamster is already equivalent to a 39-year-old human. This pet age calculator uses species-specific formulas based on veterinary research to give accurate human-year equivalents.
For more detailed results for a specific species, try our dedicated calculators: Dog Years Calculator or Cat Years Calculator.
Frequently Asked Questions
Why do different pets age at different rates?
Aging rates are tied to metabolism, body size, and genetics. Smaller animals like hamsters have fast metabolisms and short lifespans, while large parrots can live 60+ years. Each species has evolved different aging patterns.
Are these pet age conversions scientifically accurate?
The formulas are based on veterinary guidelines (such as AAHA for dogs and cats) and are good approximations. Actual aging varies by breed, diet, health, and living conditions.
Does dog size really affect aging?
Yes, significantly. Large dogs age faster than small dogs. A 10-year-old Great Dane (large) is roughly 66 in human years, while a 10-year-old Chihuahua (small) is about 56. That's why we offer separate size categories for dogs.
