How to Reduce Cat Litter Odour at Home
Share
Cat odour is one of the top concerns for cat owners — and for good reason. A smelly litter tray can take over a room fast. The good news? With the right litter and a few simple habits, you can keep your home smelling fresh all day long.
1. Scoop Daily (Yes, Every Day)
The single most effective thing you can do is scoop the litter tray at least once a day. Waste left sitting in the tray is the number one cause of odour. Clumping litter makes this quick and easy — just remove the solid clumps and you're done in under a minute. A good scoop makes all the difference: our Stainless Steel Litter Scoop is hygienic, durable, and won't hold onto odours the way plastic does.
2. Choose a Litter with Built-In Odour Control
Not all litters are equal when it comes to odour. Look for formulas that neutralise odour rather than just masking it with fragrance.
Activated charcoal is one of the most effective natural odour absorbers available. It works by trapping odour molecules at a molecular level — so smells are eliminated, not covered up. Our Activated Charcoal Clumping Cat Litter is our bestselling formula for exactly this reason, with hundreds of happy NZ customers.
If you prefer a light scent alongside odour control, our Lavender Scented Clumping Cat Litter offers a gentle, clean fragrance that keeps the tray area smelling pleasant between scoops.
3. Don't Overfill or Underfill the Tray
Aim for about 5–7 cm of litter depth. Too little and clumps won't form properly, leaving liquid to pool at the bottom. Too much and you're wasting litter. The right depth means better clumping and better odour containment.
4. Do a Full Tray Change Regularly
Even with daily scooping, litter breaks down over time and loses its odour-absorbing power. Do a full tray clean and litter replacement every 2–4 weeks — wash the tray with warm soapy water, dry it thoroughly, and refill with fresh litter.
5. Tray Placement Matters
Place the litter tray in a well-ventilated area, away from your main living spaces if possible. Avoid enclosed cupboards with no airflow — these trap odours and make them worse. A laundry, bathroom, or utility room with some ventilation is ideal.
6. Consider a Covered Tray
A hooded litter tray can help contain odours and give your cat more privacy. Just make sure to scoop even more regularly — covered trays can trap smells inside if not maintained.
7. Keep the Area Around the Tray Clean
Litter tracked out of the tray can carry odour with it. A Litter Mat placed in front of the tray catches stray litter before it spreads across your floors, making the whole area easier to keep fresh.
