Furwise is a cat health log built for households where multiple people care for multiple cats. Log feeding, water, weight, medication, and litter in seconds. Everyone in the family sees the same timeline in real time, so "did you feed them?" stops being a question.

What it does

  • Multi-cat, multi-caregiver sharing. Invite the family by link. Every entry shows up for everyone, immediately.
  • Photo health checks. Snap a photo to read your cat's mood, pain signals, and stool health. Built while caring for a sick cat, not as a marketing feature.
  • Per-cat vaccine and medication schedules. Each cat gets its own timing, not a generic template.
  • Medical history in one place. Vaccinations, treatments, deworming, blood tests, all on one timeline you can show the vet.
  • Personalized analysis. The longer you log, the more the app learns about your specific cat. Not cats in general.

Why we built it

Two years ago I adopted my first cat. Six months ago he developed a urinary issue. We rushed to the ER, came home, and couldn't sleep. My family and I took shifts watching his litter box. The hardest part wasn't the work. It was that information lived in different people's heads and phones, and when the vet asked when it started, we couldn't piece it together.

Most cat health apps stop at logging. Furwise treats logs as fuel, not the finished product. Every entry feeds the analysis: weekly patterns, alerts when something's off, comparisons to vet guidelines. The better the analysis, the more your family wants to log.

Possible disadvantages of CodePen

  • 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.

Questions & Answers

As answered by people managing CodePen and Furwise.

Which are the primary technologies used for building your product?

Furwise's answer:

  • iOS: SwiftUI
    • Backend: FastAPI on Google Cloud Run
    • Database & Auth: Supabase (Postgres)
    • AI: Google Gemini via Vertex AI
    • Subscriptions: RevenueCat + Apple StoreKit

What makes your product unique?

Furwise's answer:

Three things working together: real-time multi-caregiver sharing, photo-based mood, pain, and stool checks, and per-cat vaccine and medication schedules. None of those is rare on its own. What's different is how they fit. Easy logging means your cat's data actually accumulates in one place, and once it's accumulated, the analysis has something real to work with. Most cat apps make logging easy and stop there.

Why should a person choose your product over its competitors?

Furwise's answer:

Most cat health apps stop at logging. You enter feeding, weight, stool, and the data just sits there. Furwise treats logs as fuel, not the finished product. Every entry feeds the analysis: weekly patterns, alerts when something's off, comparisons to vet guidelines. The better the analysis, the more your family wants to log. That's the loop.

What makes the loop work: multi-caregiver sharing so entries actually get made when you have three cats and two people, photo checks for mood, pain, and stool that take five seconds, and vaccine and medication schedules tuned per cat instead of pulled from a generic template. The longer you use Furwise, the more it knows your cat.

How would you describe the primary audience of your product?

Furwise's answer:

Cat owners in multi-cat households, especially families or couples sharing daily care. Owners of senior cats, cats with chronic conditions, or anyone tired of guessing what to tell the vet.

What's the story behind your product?

Furwise's answer:

Two years ago I adopted my first cat. Like most first-time owners, I had endless questions: which vaccines, is this food toxic, is this stool normal, why did he just vomit?

Six months ago he developed a urinary issue. We rushed to the ER late at night, came home, and couldn't sleep. My family and I took shifts watching his litter box. The hardest part wasn't the work. It was that information lived in different people's heads and phones, and when the vet asked when it started, we couldn't piece it together.

That's when I started building Furwise. I'd been an engineer for years and knew what a good tool looks like. I wanted to build one for our cat, and for every owner trying to catch problems early. The photo-based mood, pain, and stool checks came out of caring for a sick cat. We wanted to share them with anyone going through the same thing.

Our vision: take care of every cat, together with the people who love them.

Furwise Reviews

  1. Beautifully Designed and Surprisingly Practical for Multi-Cat Homes

    Out of all the pet care apps I've tried, Furwise is one of the few that actually feels like someone put real thought into it. The interface is clean and modern, and everything just clicks โ€” logging feeding, meds, weight, and litter updates takes only a few seconds. Nothing feels out of place, and sharing updates with family members is surprisingly smooth. It's the kind of app that gets out of your way and lets you focus on what actually matters: taking care of your pet.
