Best Cat Litter for Odour Control in Australia
Share
One of the biggest frustrations for cat owners isn't scooping the litter tray, it's the lingering smell. Whether you have one cat or several, choosing the right litter can make a noticeable difference to how fresh your home stays.
The best cat litter for odour control doesn't simply mask unpleasant smells with fragrance. It absorbs moisture quickly, traps odour at the source, and makes daily cleaning easier by removing waste before smells have a chance to build up.
This guide compares the most common types of cat litter available in Australia, including clay, crystal, paper, pine, and tofu, to help you choose the best option for your home.
What Causes Cat Litter to Smell?
Cat urine naturally contains urea, which breaks down into ammonia as it sits in the litter tray. The longer urine remains in the litter tray, the more ammonia is produced, which is why daily scooping and good clumping are so important. Faeces also release odour-causing compounds, particularly if waste isn't removed regularly.
Several factors affect how well a litter controls odour, including:
- How quickly it absorbs moisture
- Whether it forms firm clumps that remove urine completely
- How often the tray is scooped
- The depth of litter in the tray
- Whether odours are neutralised or simply masked with fragrance
Comparing the Most Common Cat Litter Types
Clay Cat Litter
Clay litter has been the standard choice for many years because it absorbs moisture well, and most clumping varieties form firm clumps that make daily cleaning easier.
Pros
- Strong clumping
- Good odour control
- Widely available
Cons
- Can be dusty
- Heavy to carry
- Non-biodegradable
- Some products rely on added fragrances
Clay remains an effective option, but many cat owners look for alternatives that produce less dust and have a lower environmental impact.
Crystal Cat Litter
Crystal litter uses silica gel crystals to absorb moisture rather than forming clumps.
Pros
- Excellent moisture absorption
- Long-lasting
- Low dust
Cons
- Does not clump
- Urine remains in the tray until the litter is replaced
- Hard crystals may not suit every cat
- Non-biodegradable
Crystal litter performs well for odour control but requires complete litter changes once the crystals become saturated.
Paper Cat Litter
Paper litter is made from recycled paper pellets or granules and is popular with owners looking for a natural alternative.
Pros
- Low dust
- Lightweight
- Biodegradable
Cons
- Does not usually clump
- Limited odour control compared to clumping litters
- May require more frequent full litter changes
Paper litter can be a good choice for cats that need a low-dust environment. However, because urine cannot usually be removed separately, odours may become more noticeable between tray changes.
Some cat owners also prefer unscented litter options, as strong added fragrances can be overwhelming for cats. Learn more about why unscented litter is better for cats.
Pine Cat Litter
Pine cat litter, sometimes referred to as wood pellet litter, is made from compressed pine fibres or pellets. It's popular with environmentally conscious cat owners because it's biodegradable and produces very little dust.
Pros
- Low dust
- Biodegradable
Cons
- Usually does not clump
- Pellets break down after absorbing moisture
- Can require more frequent complete tray changes
Many owners appreciate pine's natural scent, although some cats dislike the pellet texture.
Tofu Cat Litter
Tofu cat litter has become increasingly popular because it rapidly absorbs moisture, forms firm clumps, and controls odours naturally, all while producing very little dust. It is made from plant-based ingredients such as pea fibre and corn starch. Learn more about what tofu cat litter is made from.
It controls odours by rapidly absorbing moisture and forming firm clumps that can be removed during daily scooping, rather than leaving urine in the tray.
Pros
- Fast, firm clumping
- Excellent natural odour control
- Low dust
- Lightweight
- Biodegradable
- Gentle on cats' paws
Cons
- Premium products may cost more upfront
- Performance varies between brands

Which Cat Litter Is Best for Odour Control?
There isn't one perfect litter for every cat or household.
If reducing odour is your highest priority, clumping litters generally perform better because urine can be removed before ammonia develops.
For many Australian households, tofu cat litter offers one of the strongest all-round combinations of:
- Strong odour control
- Firm clumping
- Low dust
- Lightweight handling
- Biodegradable ingredients
- Easy daily maintenance
Rather than masking odours with fragrance, high-quality tofu litter controls smell by trapping moisture and allowing soiled litter to be removed completely. This approach helps keep the litter tray fresher between full cleans while avoiding heavily perfumed scents that some cats dislike.
Tips for Better Odour Control
Even the best cat litter performs better when used correctly.
- Scoop urine at least once a day.
- Remove solid waste as soon as practical, as faeces can contribute to odour even when urine is well controlled.
- Maintain a litter depth of around 5 to 7 cm.
- Top up with fresh litter regularly.
- Wash and dry the litter tray before completely replacing the litter.
- Keep the litter tray in a well-ventilated area.
- Avoid overusing scented products that simply mask odours.
Frequently Asked Questions
What is the best cat litter for odour control?
Clumping litters generally provide the best odour control because they allow urine to be removed before ammonia develops. Both quality clay and tofu litters perform well, while crystal litter also offers excellent moisture absorption.
Is scented cat litter better for controlling odours?
Not necessarily. Artificial fragrances often mask smells rather than removing them. Many cats also prefer unscented litter.
Why does my litter tray still smell after scooping?
Odours can build up if the litter layer is too shallow, the tray isn't cleaned regularly, or you're using a non-clumping litter that leaves urine behind.
Does tofu cat litter control odour better than paper litter?
For many households, yes. Because tofu litter forms firm clumps, urine can be removed during daily scooping. Paper litter generally absorbs moisture but doesn't usually clump, so odours can become more noticeable as the litter becomes saturated.
Which cat litter lasts the longest?
High-quality tofu litter can be one of the longest-lasting options because it forms firm clumps that allow only the soiled litter to be removed. The remaining clean litter stays in the tray, meaning you simply top up as needed rather than replacing the entire tray frequently. How long any litter lasts will still depend on the number of cats, tray size, and how often you scoop.
Choosing the Right Litter for Your Home
The best cat litter for odour control depends on your cat, your home, and what matters most to you. If you're looking for a litter that combines odour control, easy cleaning, low dust and sustainability, tofu cat litter is one of the strongest all-round choices available.
