Switching your cat's litter is one of those things that sounds more complicated than it is. The good news: most cats take to the No Smell Club system straight away — often before you've even left the room. Here's why, and how to make the transition as smooth as possible for every cat, including the fussy ones.
Why Switch in the First Place?
If you're reading this, you probably already have a reason. Maybe your current litter isn't controlling odour as well as it used to. Maybe you're concerned about the environmental impact of clay — sodium bentonite, the most common clumping clay, is strip-mined and non-biodegradable. Maybe your cat has started sneezing more, and you've noticed the dust cloud every time you pour a new bag.
All of these are valid reasons. Clay litter has been the default for decades, but it's not the best option available anymore. Natural litters — particularly system-based approaches like No Smell Club — offer better odour control, longer lifespan, and a genuinely lower environmental footprint. For Australian households trying to reduce their impact, it's a meaningful change.
The Australian Department of Climate Change, Energy, the Environment and Water actively encourages households to move away from non-compostable, single-use products. Cat litter is one of the easiest swaps to make.
Why Most Cats Don't Need a Slow Transition
Here's something most litter guides don't tell you: cats are evolutionarily wired to toilet in soil and organic matter. The texture and smell of natural litter is actually closer to what cats instinctively prefer than the clay or silica they've been given. For most cats, switching to No Smell Club isn't a disruption — it's a return to something familiar.
In practice, this means you can often just set up the system where the old litter box used to be and let your cat investigate. Many cats will use it immediately, without any gradual introduction at all. The transition that other litter brands warn you about simply isn't as fraught with a natural, soil-based system.
Step 1: Set Up the System in the Same Spot
Place the No Smell Club system exactly where the old litter box was. Add the mineral base layer first — approximately 3–4 cm deep — then add the biologic top layer at approximately 2 cm. The layers need to be in the right order to work correctly.
Apply the bioenzyme solution to the top layer as directed. This kick-starts the microbial environment that makes the system effective. Within a few days, the beneficial bacteria will be established and the system will be working at full capacity.
For most cats, that's all you need to do. Watch what happens — you may be surprised how quickly they take to it.
Step 2: For Extra Reassurance, Sprinkle Some Old Litter on Top
If you want to smooth the transition further — or if your cat is on the cautious side — sprinkle a thin layer of their old litter on top of the biologic layer. The familiar scent and texture on the surface can help bridge the gap while they get used to the new substrate underneath.
This step is optional for most cats, but it's a simple thing to do and costs nothing extra.
Step 3: For Particularly Fussy Cats, Mix Old and New Gradually
The standard approach for switching any litter is to mix old and new gradually over one to two weeks — starting at around 20–25% new litter and increasing the proportion every few days until you've fully transitioned. This works well for cats that are especially particular about texture or routine.
With No Smell Club, you're less likely to need this level of hand-holding than with other litter types — because most cats genuinely like the texture. But if your cat is one of the fussy ones, the gradual mix method is there as a fallback and it works reliably.
The Australian Veterinary Association notes that sudden litter changes can trigger avoidance behaviour in sensitive cats. The gradual approach removes that risk entirely for cats that need it.
Step 4: Maintain the System Properly
Once your cat is using the system, maintain it as directed. Scoop solid waste daily if possible — this extends the life of the biologic layer significantly. Top up the biologic layer as it depletes using the soil refill. Replace the mineral base every two to three months depending on usage.
One of the biggest adjustments for cat owners switching from clay is realising they don't need to do full litter changes as frequently. The system is designed to last — trust it.
What to Expect in the First Month
In the first week, the microbial environment is still establishing itself. You may notice a faint earthy smell — this is normal and will fade as the beneficial bacteria become established. By week two, the system should be working at full capacity and odour should be minimal.
By the end of the first month, most Australian cat owners report that they've stopped thinking about the litter box entirely — which is exactly the point. A system that works doesn't demand your attention.
When the Transition Is Complete
You'll know the transition is successful when your cat is using the box consistently and you're not noticing any odour. At that point, you can settle into a maintenance routine and enjoy the benefits: less frequent changes, no chemical fragrance, and a litter that goes on the garden when you're done with it rather than into landfill.
For Melbourne cat owners in apartments or townhouses without much outdoor space, the compostable nature of the system is a genuine bonus — even a small balcony planter benefits from the nutrient-rich spent litter.
