Every pet parent asks the same question: Is my pet healthy?

Vet visits give you snapshots. Lab results give you numbers. But nothing gives you a single, clear answer that tracks over time — until now.

The Pet Longevity Score is a proprietary health metric built by Furever that scores your pet's overall wellbeing on a scale of 0 to 100. It's calculated across six health pillars and updates every time you add new health data.

How the Longevity Score Works

Think of it as a credit score, but for your pet's health. Instead of financial data, it draws from veterinary records, AI health checks, activity data, and more.

The score updates dynamically. Upload a blood panel? The score adjusts. Log a week of daily walks? It reflects that too. Skip a booster vaccine? You'll see the impact.

The 6 Health Pillars

The Longevity Score is calculated across six distinct pillars, each capturing a different dimension of your pet's health:

1. Organ Strength

Tracks liver, kidney, and pancreatic function through biomarkers extracted from blood work and vet records. Early detection of organ stress is one of the most impactful things you can do for longevity.

2. Inflammation

Monitors markers like C-reactive protein, white blood cell counts, and other inflammatory indicators. Chronic low-grade inflammation is a silent contributor to aging in both humans and pets.

3. Metabolic Health

Evaluates glucose levels, thyroid function, weight trends, and Body Condition Scoring (BCS). Metabolic health is foundational — it affects energy, organ function, and disease risk.

4. Body Activity

Captures walk frequency, duration, activity streaks, and overall movement patterns. Regular physical activity is one of the strongest predictors of a longer, healthier life for dogs and cats.

5. Blood Immunity

Assesses vaccination status, immune response markers, and complete blood count data. A strong immune system is your pet's first line of defense against disease.

6. Hormonal Harmony

Tracks hormonal balance through thyroid panels, cortisol levels, and reproductive health indicators. Hormonal imbalances can affect everything from weight to behavior to cancer risk.

What Makes It Different

Most pet health apps track individual data points — a weight here, a vaccine there. The Longevity Score connects everything into a unified picture.

It's contextual. A blood panel result means more when it's combined with activity data and body condition trends. The score considers how different health dimensions interact.

It's trending. You don't just see a number — you see how it changes over time. A score of 72 that's been climbing for three months tells a very different story than a 72 that's been declining.

It's actionable. Each pillar shows exactly where your pet is strong and where they need attention. Layla, your AI concierge, uses the score to prioritize recommendations.

How to Improve Your Pet's Score

The best part about the Longevity Score is that it responds to action. Here are the highest-impact things you can do:

Upload vet records regularly. Every blood panel, urinalysis, and checkup report adds data that makes the score more accurate and complete.
Log daily walks. Consistent activity is one of the easiest ways to improve the Body Activity pillar.
Keep vaccinations current. Expired or missing vaccines directly impact the Blood Immunity pillar.
Do AI health checks. Photo-based BCS scoring takes 30 seconds and feeds into Metabolic Health.

Data Completeness Matters

The Longevity Score includes a data completeness indicator that shows how much health information Furever has to work with. A score based on a single vet visit is less reliable than one built from months of records, walks, and health checks.

As you add more data, the score becomes more accurate — and more useful. Think of it as training a model: more input, better output.

Who Is It For?

The Longevity Score is designed for every pet parent who wants to be proactive about their pet's health. Whether you have a puppy or a senior dog, a kitten or an aging cat — the score gives you a clear, evolving picture of their wellbeing.

It's especially valuable for:

Senior pet owners who want to catch age-related decline early
Multi-pet households where tracking individual health can get complex
Health-conscious pet parents who already track their own health metrics
Frequent travelers who need to ensure their pet's health records are always current
