    Frequently asked questions

    How can I help my dog live longer?

    The habits with the biggest impact are keeping a lean weight, daily exercise, dental care, routine vet visits, parasite and vaccine prevention, a balanced diet, and spaying or neutering. Lean weight alone can add about two years.

    How can I help my cat live longer?

    For cats, keeping them safely indoors is the single biggest factor, followed by a lean weight, dental care, quality diet with hydration, prevention, and routine vet visits.

    What is a longevity score?

    It's a friendly, educational tally of the lifestyle habits most linked with a long, healthy pet life. A higher score means you're doing more of the things that help — and the tool shows which steps could help even more.

    Is the longevity score a prediction of lifespan?

    No. It's an encouraging snapshot of habits, not a lifespan prediction. For an estimate of years, try the dog or cat lifespan calculator.

    How this calculator works
    1. Choose dog or cat, then tick the habits you currently keep up.
    2. Each habit carries points based on how strongly it's linked with longevity.
    3. Your score, grade, and a list of gentle next steps appear instantly.

    Input guide
    • Be honest — the value is seeing exactly which loving changes could help most.
    • For cats, indoor living carries the most weight by far.
    • For dogs, a lean weight is the single most powerful habit.

    Result explanation

    A higher score means you're already doing many of the things that help pets thrive.

    A lower score is simply an invitation — the suggested steps are the ones that help most.

    The score reflects habits, not a guaranteed lifespan.

    Helpful tips
    • Re-take the score after adopting a new habit to watch it climb.
    • Lean weight and dental care are two of the kindest, most powerful gifts.
    • Pair this with the lifespan calculator for an estimate of years.

    Common mistakes
    • Thinking small habits don't matter — they genuinely add up.
    • For cats, underestimating the impact of outdoor roaming.
    • Letting weight creep up unnoticed.
