About Clowder

I built Clowder
for my mother's cattery.

Clowder is software for cat breeders: the cats, litters and health tests you keep in one app become your cattery's public website. I built it for my mother, Lana, who breeds Maine Coons in Québec. Her cattery, Z-COON, still runs on it today.

— I set up every cattery myself.

How it began

First built for one cattery. Ours.

My mother, Lana, has bred Maine Coons in Québec since 2016: registered with TICA and ACFA, a binder full of pedigrees, a phone full of kitten photos, and the same Sunday-night dread of a website that was always a season out of date.

So I built her one place for the whole cattery: cats, litters, pedigrees, health results, and the buyers' inquiries, with a public website that assembles itself from those records. Add a kitten, file a health test, mark a litter reserved; the page follows on its own. No templates. No publish button.

That cattery is Z-COON. It still runs its cats, its litters and its inquiries on Clowder today. It was the app's first home and my first customer, and you can go and check it right now.

Once I saw what it gave her back, the hours and the buyers who arrived already trusting, I opened Clowder to every breeder.

You raise the cats. The website keeps itself.

What we believe

You're a breeder, not a web designer.

Website builders ask you to think in pages, sections and themes. Breeders think in cats, litters and health results. That mismatch is why so many good catteries have no site, or one that's a year out of date, and why you walk away feeling bad at computers, when the tool was built for the wrong person.

Clowder removes that whole job. You should feel like you're caring for your cats, never like you're maintaining a website. Saving in the app is the website updating. That is the entire idea.

Built around cats, not pages.
A real person sets you up: me, in French or English, evenings and weekends included.
Your records and your domain stay yours. If you ever leave, they leave with you.
Who's behind it

Me, and my mother.

Clowder is one person, not a company. I'm Mikhail Zadvornov, from Québec: I grew up around my mother's cattery, I wrote every line of Clowder, and I set up every cattery myself, over a call or at your kitchen table. When you write to Clowder, I'm the one who answers, and I keep breeder hours.

Proof, not promises

See it running, right now.

Z-COON is my mother's cattery, Clowder's first customer, and the site I'll show you on our call. Everything on it, from the kitten pages to the health results with their dates, is assembled by Clowder from her records. Look around: it's a cattery page no one had to design.

Ready for yours.

If you keep a cattery, I'd love to set yours up, the same way I set up my mother's. Book a session and I'll sit with you. If Clowder isn't a fit, the setup fee comes back to you.
