CatMD is your cat's voice in your pocket.

The more you use it, the more it becomes your cat. Every check-in, photo, named person, and body-language read sharpens the cat that lives in the app โ€” the one who writes a diary every night, sends postcards in their own voice, drops a daily card to your home screen, and replies when you chat. After a few weeks, the diary and chat stop sounding like "an AI" and start sounding like the cat at home. Plus vet-grade triage when something feels off. Built for cats only.

๐Ÿพ TODAY โ€” 15-second check-in (mood, appetite, litter). 6-second body-language reads with channel-by-channel interpretation. Health Rhythm spots drift before symptoms.

๐Ÿพ BOND โ€” Where your cat takes shape. โ€ข Personality: 9 archetypes from the Litchfield Feline Five โ€ข Daily Diary in your cat's voice โ€” references recent days, named family, things you've told them โ€ข Daily Card: today's vibe, ready to share โ€ข People & Pets: tag who's in the photos; names get woven into the diary โ€ข Becoming: 7-facet identity score showing how shaped your cat is in here โ€ข Posters: a new theme every week โ€” movie hero, famous painting, Studio Ghibli scene, 80s anime

๐Ÿพ CHAT โ€” Your cat replies in their own voice. First-person, in their archetype, with the day's mood (grumpy, mischievous, theatrical, philosophical, megalomaniac โ€” resets at midnight). They remember the diary, named people, and things you've told them about themselves. Every reply is screenshot-worthy. Vet-grade safety net when symptoms come up.

๐Ÿพ TRIAGE โ€” 60-second photo + symptom scan with a 0โ€“99 score and 4 urgency tiers. Feline Grimace Scale (Univ. Montreal 2019). Sleeping respiratory rate monitor for HCM. Vet-ready PDF export.

WHY CATMD? AI that knows YOUR cat โ€” breed, personality, named family, diary, mood arc, self-facts. Cat-only. Private by design. Daily ritual, not crisis tool.

โš ๏ธ Informational only. Not veterinary advice. In an emergency, contact your nearest vet immediately.

  • Cross-Device Accessibility
    Being an online platform, CodePen can be accessed from any device with an internet connection, making it convenient for developers on the move.

Possible disadvantages of CodePen

  • Limited Offline Functionality
    Since CodePen is primarily an online tool, it requires an internet connection for most of its features to work, limiting its usefulness in offline environments.
  • Performance Constraints
    Complex or resource-intensive projects may not perform as well on CodePen as they would in a full-fledged local development environment.
  • Subscription Costs
    While many features are free, advanced functionalities and additional storage options require a paid subscription, which may not be ideal for all users.
  • Limited Backend Capabilities
    CodePen is primarily designed for front-end development, so it offers limited support for backend technologies, making it less suitable for full-stack or server-side development.
  • Dependency Management
    Managing dependencies and libraries can be cumbersome compared to local development environments which have better tools for this purpose, like npm.
  • Security Concerns
    Sharing projects with the public can expose your code and assets to unauthorized use, posing potential intellectual property and security risks.

CatMD.pet features and specs

  • Convenient Access to Veterinary Guidance
    CatMD.pet provides cat owners with quick access to veterinary information and guidance online, making it easier to get answers about cat health concerns without immediately needing to visit a vet in person.
  • Cat-Specific Focus
    Unlike general pet health platforms, CatMD.pet is specifically focused on cats, meaning the information and advice provided is tailored to feline health needs, behaviors, and conditions.
  • Cost Savings Potential
    By offering initial health assessments or guidance online, the platform can help cat owners save money by determining whether a vet visit is truly necessary or if a concern can be managed at home.
  • 24/7 Availability
    As a digital platform, CatMD.pet can be accessed at any time of day or night, which is particularly useful when cat health concerns arise outside of regular veterinary office hours.
  • Educational Resource
    The platform serves as an educational tool for cat owners, helping them learn more about common feline health issues, symptoms to watch for, and preventive care practices.

Analysis of CatMD.pet

Questions & Answers

As answered by people managing CodePen and CatMD.pet.

What's the story behind your product?

CatMD.pet's answer:

CatMD started with a 2 AM Google search โ€” the kind every cat parent knows. The cat is acting "off," the forums offer contradictory anxiety, and the only symptom checkers available treat cats like dogs in smaller bodies. Amit Raina, the founder, is a Singapore-based solo developer with nearly a decade of consumer-app experience and a household run by cats. He couldn't accept that "better information when it matters most" wasn't a solvable problem. CatMD is the answer to that night: cat-only, vet-source-cited, structured enough to be useful at 2 AM and again at the vet's office the next morning.

What makes your product unique?

CatMD.pet's answer:

CatMD is the only AI vet triage app built exclusively for cats โ€” not a generic pet app retrofitted. Its knowledge base is curated from five peer-reviewed feline-only sources (Merck Veterinary Manual, AAFP, Cornell Feline Health Center, ISFM, ASPCA Poison Control), and its outputs include the Feline Grimace Scale (research-grade pain scoring from a single photo), a sleeping respiratory rate monitor (early heart-disease signal), and chronic-condition dashboards for CKD and hyperthyroidism. Every triage produces a 0-99 health score with a clear urgency recommendation โ€” Emergency, Vet Soon, Monitor, or Low Concern โ€” in under 60 seconds.

Why should a person choose your product over its competitors?

CatMD.pet's answer:

Most pet symptom-checker apps (Petriage, Buddydoc, TTcare, PawScan AI, Maeve by Barkibu) are generic across all species, which dilutes signal for cat-specific conditions. The closest cat-focused competitor (Sylvester.ai) does pain assessment only. CatMD is the only product that combines cat-only knowledge depth + structured 0-99 scoring + Feline Grimace Scale + sleeping respiratory rate + CKD/thyroid dashboards + vet-ready PDF export + anonymous-by-default UX. The decision support is calibrated specifically to feline biology and behavior, not "averaged" across species.

How would you describe the primary audience of your product?

CatMD.pet's answer:

Anxious cat caregivers โ€” owners who notice their cat acting "off" but aren't sure if it's serious enough for a vet visit. Cats are masters at hiding illness, so caregivers often face uncertainty (delayed vet visits, unnecessary ER trips, late-night Google spirals). CatMD's primary users are typically multi-cat households, owners of senior or chronically-ill cats, and first-time cat parents. Secondary audience includes veterinary professionals who want a structured pre-visit triage report from clients.

Which are the primary technologies used for building your product?

CatMD.pet's answer:

React Native + Expo (Android-first, iOS in progress), Supabase for auth and cloud sync, RevenueCat for payments and entitlements, PostHog for product analytics, OpenAI's gpt-4o-mini for triage reasoning (with gpt-4o for emergency-level escalation), and a custom feline knowledge pipeline that ingests peer-reviewed veterinary references and applies VCPR/FDA-compliant prompt guardrails. Hosted on Cloudflare Workers (catmd.pet) for the proxy layer. Closed beta on Google Play; iOS TestFlight planned post-Android public launch.

Who are some of the biggest customers of your product?

CatMD.pet's answer:

  • Currently in pre-launch Android closed beta โ€” no public customers yet
  • B2C consumer application; not enterprise-targeted
  • Beta tester pool building up via maker communities (BetaTribe, Reddit r/SideProject, IndieHackers, Telegram beta-tester groups)
  • Public launch on Google Play planned within weeks; iOS to follow ~2 months later
