Frequently Asked Questions
How do cats age compared to humans?
Cats age much faster than humans in their first two years. The first year equals about 15 human years, the second year adds 9 more years, and each subsequent year is approximately 4 human years.
Why do cats age faster than humans?
Cats have a faster metabolism and reach maturity more quickly than humans. Their shorter lifespan means they progress through life stages more rapidly, particularly in their early years.
Do indoor and outdoor cats age differently?
While they age at the same rate, indoor cats typically live longer due to reduced exposure to risks like accidents, diseases, and predators. Indoor cats can live 12-18 years, while outdoor cats often live 8-12 years.
How can I tell my cat's age without papers?
A veterinarian can estimate your cat's age by examining their teeth, coat, eyes, and muscle tone. Teeth are particularly useful as kittens get their adult teeth at specific ages.
What age is considered senior for cats?
Cats are typically considered senior when they reach 11 years old (about 60 human years). However, cats 15 years and older are considered super senior and may need special care.
