Will Petus replace my vet?

No — and it will tell you so. Petus handles the everyday: the “is this normal?” questions, the photo checks, the record-keeping, the trends. Its job is to tell you clearly when something deserves a vet’s eyes, and to hand your vet the full story when it does. Whenever it’s unsure, it says “see a vet” — it never guesses past its evidence.

Is Petus free to use?

Yes. Chat, photo symptom checks, the health record, reminders — free, no card. Petus on-demand vet consults are rolling out as simple pay-as-you-go; you choose each one, so there’s never a surprise charge.

How does Petus know what it knows?

Its advice is grounded in published veterinary guidance — WSAVA, AAHA, IRIS and other bodies vets themselves follow — combined with what it has learned about your pet: breed, age, history, the trends in their record. It cites its sources in chat, and it’s built to be cautious rather than clever.

What happens to my pet’s data?

It’s yours. The record belongs to you — export it, share it with your vet, or delete it whenever you like. We never sell it.

Which pets does Petus support, and where?

Dogs and cats today, starting in the UK. We’re opening area by area — if Petus isn’t live where you are yet, join the waitlist and your invite will land the moment it is.

What’s new: Petus learns to read blood work

Upload a lab report and get it back in plain English — plus a trend engine that watches results over time and flags slow drifts a single snapshot would miss.

Lab results are where good news goes to become anxiety. You get a PDF of forty numbers, three of them starred, and a follow-up appointment in two weeks. This release is about turning that PDF into something a human can act on.

The lab report reader

Upload blood work — a photo or the PDF your clinic emailed you — and Petus reads it back in plain English: what was measured, what's in range, what's slightly off and what that usually means at your pet's age and breed. Every analyte is mapped to a proper canonical reference — species-specific ranges, not one-size-fits-all — so a greyhound's naturally odd numbers don't set off false alarms.

The trend engine

One blood panel is a snapshot. The value is in the sequence — and that's where Petus now earns its keep. Each result joins your pet's history, and a conservative statistical engine watches the direction of travel: kidney values drifting up slowly across three panels, weight easing down month over month.

Two things we built in deliberately:

It abstains when it can't be sure. Two data points don't make a trend, and Petus won't pretend they do.
It escalates in plain terms. "This has been rising since January — worth showing your vet" rather than a red exclamation mark and vibes.

Grounded answers, with sources

Behind the scenes, Petus's clinical answers are now grounded in a curated veterinary knowledge base, with citations checked before anything reaches you. If Petus tells you chocolate toxicity scales with body weight and cocoa content, that's not a hunch — it's sourced, and we verify the sources.

For the vets

The clinical portal grew up too: vets who've been given access now see a referral-grade record — problem list, medication history, vaccination status, weight and lab trends — the shape of record they'd want from a referring practice, built automatically from what you've logged.

None of this replaces your vet reading the results properly. It replaces the two weeks of not knowing what the starred numbers mean.
