With so many cat litter options available today — clay, crystal, paper, wood and plant-based — choosing the right one can feel overwhelming.
Cats are known for being selective, and once they’re comfortable with a particular litter, changing it isn’t always easy. That’s why understanding how different types of litter work — and their potential downsides — is essential for both your cat’s health and your home.
Below, we take a closer look at the most common types of cat litter in Australia, comparing them based on:
-
Ingredients
-
Odour control
-
Ease of cleaning
-
Cat preference
-
Clumping ability
-
Cost over time
-
Environmental impact
Clay Litter
Clay litter is one of the most widely used options and is familiar to many cat owners. It clumps well and controls odour reasonably effectively.
However, it also comes with several drawbacks.
Key Concerns
-
Dust: Clay litter can produce fine dust, which may irritate both feline and human respiratory systems — particularly in enclosed indoor spaces.
-
Sodium bentonite: This clumping agent can stick to paws and be ingested during grooming. In large amounts, it may cause digestive discomfort.
-
Environmental impact: Clay litter is strip-mined, which can damage natural habitats and ecosystems.
Summary:
Clay litter is affordable and easy to find, but it may not be the healthiest or most sustainable long-term option.
Crystal (Silica) Litter
Crystal litter is made from silica gel and is highly absorbent, meaning it often needs changing less frequently.
Key Concerns
-
Hard texture: Many cats find crystals uncomfortable on their paws.
-
Dust inhalation: Fine silica dust may irritate airways over time.
-
Hygiene: While odours are absorbed, bacteria can remain if litter isn’t replaced regularly.
-
Chemical indicators: Some crystal litters use colour-changing additives that may not suit sensitive households.
Summary:
Crystal litter offers strong absorption but may compromise comfort and air quality, especially for indoor cats.
Paper Litter
Paper litter is typically made from recycled paper and comes in pellets or granules.
Key Concerns
-
Weak clumping: Most paper litters absorb moisture but don’t form firm clumps, making odour control more difficult.
-
Frequent replacement: Trays often need changing more often.
-
NO odour control: Ammonia smells can build up quickly.
Summary:
Paper litter is lightweight and low-dust, but performance and cost over time can be less practical for everyday use.
Wood Litter
Wood litter is usually made from recycled timber products and formed into pellets or granules.
Key Concerns
-
Poor clumping: Urine often breaks pellets down into sawdust rather than forming scoopable clumps.
-
Strong natural scents: Pine-based litters in particular can be unpleasant for cats.
-
Limited odour control: Additional additives are sometimes required to compensate.
Summary:
Wood litter appeals to eco-minded owners, but many cats dislike the texture and scent.
Plant-Based (Tofu) Cat Litter
Plant-based litter — often called tofu litter — is made from ingredients such as soybean fibre, corn starch, peas and tapioca.
Benefits
-
Soft, gentle texture preferred by many cats
-
Excellent clumping and absorption
-
Naturally low dust
-
Easy daily cleaning
-
Suitable for indoor and apartment living
What to Watch For
Not all tofu litters are created equal. Some products:
-
Add strong fragrances (lavender, fruit, green tea, spices) that cats dislike
-
Use inconsistent ingredient ratios, affecting clumping and odour control
Quality and formulation matter.
How to Choose the Right Cat Litter
Odour Control
Effective litter manages odour in two ways:
-
Physical absorption (plant fibre, clay, charcoal)
-
Chemical neutralisation (pH balance, baking soda)
Plant-based and crystal litters typically perform better than clay, paper or wood alone.
Ease of Cleaning
Good clumping and strong absorption make daily maintenance faster and cleaner.
-
Best clumping: Plant-based litter
-
Weakest clumping: Wood and crystal litter
Value for Money (Long-Term Cost)
Initial price can be misleading. Some cheaper litters require frequent full changes, increasing daily cost.
Approximate daily cost in Australia:
-
Clay: under $1.00/day
-
Paper: over $2.00/day
-
Wood: over $1.50/day
-
Crystal: over $1.50/day
-
Plant-based: under $1.00/day
High-performance clumping litter often lasts longer — saving money over time.
Final Thoughts
The best cat litter is one that suits:
-
Your cat’s preferences
-
Your living space
-
Your lifestyle and budget
For apartment living, indoor cats or homes where litter trays are close to living areas, low-dust, odour-reducing, clumping litter is often the most practical choice.
At Tofu Cat Litter Australia, we focus on creating litter that works with your cat’s natural instincts — clean, gentle, effective and designed for modern Australian homes.
