Frequently Asked Questions

Why is the pet age calculator dog to human years based on DNA methylation?
Genetics researchers at UC San Diego discovered that dogs age epigenetically much faster than humans in their first two years, but their aging slows down significantly later in life. A pet age calculator dog to human years using DNA methylation shows that a 1-year-old dog has cellular methylation equivalent to a 31-year-old human.
How does the cat years to human years calculator breed specific model feline aging?
The cat years to human years calculator breed specific models a cat’s rapid development: age 1 equals ~15 human years, age 2 equals ~24 human years, and every subsequent year equals approximately 4 human years.
How does the bird age in human years calculator evaluate parrots vs small birds?
The bird age in human years calculator accounts for metabolic longevity: small passerines (canaries/finches) live 10-15 years, while large psittacines (Macaws, African Greys) can live 50-80 years, aging at a much slower human-equivalent rate.
