A cat reaches maturity faster than a human.
The lifespan of a cat can be up to 21 years or more.
Puberty is seen at 1 year and early adulthood at 2 years.
After 2 years of age the comparable age between humans and cats shows a linear relationship.
For the first 2 years of a cat's life:
comparable human age in years =
= (-2.75 * ((cat age)^2)) + (17.55 * (cat age)) + 0.05
After 2 years of age:
comparable human age in years =
= (4 * (cat age)) + 16
If this equation is rewritten:
comparable cat age after 2 years of age =
= (0.25 * (human age)) - 4
