A little context
Why We Built PurrAge
A more useful way to understand the years behind every nap, headbutt, and birthday treat.
The old myth
Why We Built PurrAge
Most "cat years" calculators still use the old rule everyone grew up with — one cat year equals seven human years. It's catchy, it's memorable, and it's wrong. Cats don't age at a steady rate: they mature explosively in their first two years, then settle into a slower, steadier pace for the rest of their lives.
PurrAge uses the veterinary-recognized formula instead — the same age curve vets actually reference — so the number you get back means something real, not just a fun fact.
More than a number
What Makes This Different
A number alone doesn't tell you much. That's why every result on PurrAge is tied to one of six life stages — kitten, junior, prime, mature, senior, and geriatric — each with a short, honest note on what tends to change at that point in a cat's life. It's meant to be a starting point for paying closer attention, not a replacement for actual veterinary guidance.
Small and focused
Our Approach
PurrAge is a small, focused tool. We're not trying to be everything for every pet — just genuinely good at the one thing we do. As the site grows, we'll be adding breed-specific guides and deeper life-stage content, always grounded in real research rather than guesswork.
