Your house shouldn't smell like a litter box. Period.

Traditional boxes trap odors inside your room, and standard air purifiers only catch floating fur.

Kacau seals the air inside the litter system, pulls stink away before it can spread, and vents it completely out of your home. Zero odor. Zero stress.

We are currently looking for local alpha testers in KL & JB to try out our first batch of functional prototypes.

🔒 Limited prototype slots available for the initial cohort.
🪟 Setup

Snaps Into Any Window

Uses a slim, flexible hose and an adjustable kit that fits perfectly into sliding, swing, or grilled windows without letting bugs or weather inside.

🐱 Safety

Cat-First Safety

The quiet airflow system pauses instantly the absolute second your cat steps inside the box, keeping them completely safe and comfortable.

📊 Insights

Simple Health Alerts

Gently monitors how often your cat visits each day, sending a quick heads-up to your phone if their routine changes so you can spot health issues early.

Why True Source Extraction Wins

Automatic Boxes

The "Closet" Effect

They move the waste around, but the smell stays trapped inside a plastic drawer right in your room. Opening it up to clean it out is a nightmare.

Room Air Purifiers

Meant for Dust, Not Odor

They are great for cat dander and dust, but heavy gases pass right through their thin filters. Your room still ends up smelling like pee.

The Kacau Way 🏆

Total Air Freshness

We trap the air inside the enclosed box and gently push it outside. The odor never even gets a single chance to enter your room.

Hey there! We're Kacau.

We’re a tiny team of Malaysian cat lovers based in KL and JB. In our past lives, we worked as hardware designers for places like Dyson, building high-end airflow tech. But at home, we had the same annoying problem as every other cat owner: expensive litter boxes that still smelled bad and were impossible to wash. We realized you don't need over-complicated robots to fix litter odor; you just need to move the air the right way. So, we built Kacau to fix the root problem simply and safely.
