The Modern Science of Cat Aging
The old myth of "one cat year equals seven human years" is inaccurate because cats age much more rapidly in their early life. According to guidelines from the American Association of Feline Practitioners (AAFP), a cat's first year is equivalent to about 15 human years. Their second year adds another 9 years, making a 2-year-old cat about 24 in human years. After that, each subsequent cat year is roughly equal to four human years. Our calculator uses this scientifically-backed model.

Understanding Your Cat's Life Stage
Knowing your cat's life stage helps you provide the best possible care. Each stage has unique health, nutrition, and enrichment needs.
Tips for a Long & Healthy Feline Life

- Keep Indoors: Keeping your cat indoors is the single most effective way to extend their lifespan by protecting them from cars, predators, and infectious diseases.
- Regular Vet Visits: Annual checkups for adult cats and bi-annual visits for seniors are crucial for preventative care and early disease detection.
- Mental & Physical Enrichment: Keep your cat engaged with puzzle toys, scratching posts, and regular playtime to maintain a healthy weight and sharp mind.
- Dental Health: Dental disease is common in cats. Regular dental checkups and at-home care (like brushing or dental treats) are important.
- Clean Litter Box: A clean litter box is essential for your cat's comfort and can help you monitor for any urinary health issues.
