How old is my cat in human years?

A 1-year-old cat is roughly 15 human years. A 5-year-old is about 36. Our calculator uses the AAHA/AAFP feline life stage guidelines. After age 3, each cat year adds approximately 4 human years — a 10-year-old cat is about 56 human years, and a 15-year-old is about 76.

AAHA/AAFP 2021 guidelines: Kitten (0-6 months), Junior (7 months-2 years), Prime (3-6 years), Mature (7-10 years), Senior (11-14 years), Geriatric (15+ years). Each stage has different health and checkup needs.

How long do cats live?

Indoor cats live 12-18 years on average, with many reaching 20+. Outdoor cats average only 2-5 years due to traffic, predators, disease, and environmental hazards. Key longevity factors include indoor lifestyle, regular veterinary checkups, species-appropriate nutrition, dental care, and maintaining a healthy weight.

When is a cat considered a senior?

Cats are considered "Senior" at 11-14 years (roughly 56-76 human years) and "Geriatric" at 15+ years. However, age-related changes begin earlier: kidney function decline can start at 7-8 years, and dental disease is prevalent by age 3. AAFP recommends biannual exams starting at age 7-8.

What health screenings do senior cats need?

AAFP recommendations for senior cats (11+ years): biannual exams with blood work (CBC, chemistry, thyroid T4), urinalysis (checking for protein loss and concentration), blood pressure screening (hypertension often accompanies kidney disease and hyperthyroidism), and dental assessment. Early detection of chronic kidney disease is critical — it affects 30-40% of cats over 10.

How does cat aging compare to dog aging?

Cats age similarly to dogs in early years but maintain a more consistent aging rate throughout life. A 10-year-old cat (~56 human years) has aged more slowly than a large-breed dog of the same age (~66-70 human years). Cats' consistent aging rate contributes to their longer average lifespan.
