PolysRock is a small hobby cattery in Amsterdam. Our goal is to breed healthy, sweet and confident kittens.

This site was created for the love of my cats. For the Maine Coon in general, and the Maine Coon Polydactyl in particular. We love those big paws!

About PolysRock

Hi, I'm Winnie

I live with my love Hugo and five Maine Coons in a two‑floor apartment in the nicest part of Amsterdam, near the Museum Square. The cats can roam the whole house and our 10 m² south‑facing balcony.

Since 2013 we occasionally breed a litter under the name PolysRock, registered with TICA, and specialised in the Maine Coon Polydactyl. My goal is straightforward: breed healthy, sweet and confident kittens who end up with staff that will love them for life.

kittens on
the way

We occasionally breed a litter, at most one or two a year. Every kitten grows up in our living room, fully socialised, and only leaves home when we're sure we've found it the right staff.

Kutie Pie × Warjo

This spring Kutie Pie went on a date with Warjo. She was a little unsure at first, a strange house and a strange tomcat. She kept her distance for a while, but Warjo turned out to be a complete gentleman: patient, soft‑spoken, never once pushy. By the end of the visit she had quite melted for him. We hope that we'll get to meet their kittens at the end of July. Thank you Patrick for your trust and making this mating possible.
