01 — SLOT
Panels slot together
Six die-cut panels per module. Tabs press into slots by hand — assembly takes about two minutes.
Made of cardboard. Loved by cats.
A modular playground your cat rebuilds with you.
4Cat modules are flat-packed cardboard cubes that slot together without glue or tools. Stack them, clip them, tear them down and build something new — a tower on Monday, a maze on Friday.
You're on the list — we'll write when the first kits are ready.
First production run is limited. No spam, one email when we launch.
How it works
Three moves. No instructions your cat could shred.
02 — BUILD
Every cube is a room
Each cube comes pre-designed — portholes, paw cutouts, steps or peepholes — so a module arrives as a den, a lookout or a tunnel.
03 — REARRANGE
Clip, stack, repeat
Cardboard clips lock modules side by side or on top of each other. Unclip and rebuild whenever the cat gets bored.
Compositions
Same modules, different playground.
A starter kit builds any of these. Add modules over time and the playground grows with your household.
The Ridge
The Loft
The Wall
Boxes are already your cat's favorite toy.
We just made them stackable, sturdier and worth keeping in the living room. When a panel finally gives in to the claws, recycle it and slot in a new one.
FAQ
Questions humans ask.
Yes — the panels are double-wall corrugated cardboard, and the slotted construction spreads weight across the whole cube. An assembled module comfortably holds an adult cat on top.
Eventually, and that's fine — scratching is part of the fun. Panels are replaceable one at a time, so a well-loved corner doesn't mean replacing the playground.
That's the plan: starter kits first, then individual modules, replacement panels and clip packs so your setup can grow (or heal) over time.
The whole product is cardboard with water-based coloring. When a panel is done, it goes straight into paper recycling.

Who we are
A very small studio with one very demanding client.
4Cat started at home, with a cardboard box that outlasted every toy we ever bought. Every module we design gets built, sat in, chewed on and rearranged before it goes anywhere near production.
If our CEO approves it, we make it. If he sleeps somewhere else, back to the drawing board.
