Your Questions About Cat Litter Answered by Dr. Tanya

As a veterinarian, many people ask me health-related questions about their cats. Diet choices and behavioural issues are two common topics.. But cat litter comes up more than you might expect. And judging by Google searches, many Australian cat parents are asking similar questions about which cat litter is safest for their cats and their home.

Below, I’ve answered some of the most-googled cat litter questions in Australia, based on my knowledge and experience as a vet, and as a cat parent with multiple kitties under one roof.

How often should I change cat litter?

This is one of the most common questions I hear. The answer depends on the type of litter you’re using and how well it clumps.

As a general guide:

• Clumping litter should be scooped daily and fully replaced every 2–4 weeks

• Non-clumping litter can need full tray clean and refreshing every day. 

If a litter clumps well and contains moisture effectively, you can remove waste without contaminating the rest of the tray. Poor clumping leads to unnecessary litter waste, as more litter is thrown away with each clean or when urine spreads through the tray instead of staying contained.

For hygiene and odour-control, good clumping means fewer full tray changes. This is better for both your cleaning routine and reducing household waste.

What biodegradable cat litter options are available in Australia?

When people search for biodegradable cat litter options in Australia, they’re usually trying to reduce landfill waste. But they’re still searching for a high-quality product.

Common biodegradable and natural cat litter options include:

• Tofu cat litter

• Paper-based litter

• Wood fibre or pellet litter

• Corn-based litter
  
  

Each type works differently, as it has different properties. Plant-based options are generally lighter, renewable, and they break down easier than clay.

From a veterinary standpoint, the key is the formulation. A well-designed biodegradable litter should still:

• Absorb moisture efficiently

• Clump reliably

• Produce minimal dust

• Easy to clean and dispose of

• Help manage litter odour

• Prevent stress between cats in the same household

Eco-friendly doesn’t mean poor performance. Modern natural litters have come a very long way and are now the most sought-after types of cat litter.

What is the best cat litter for odour control?

Odour control isn’t about added fragrance in a cat litter; it’s about how well it handles moisture.

Urine odour develops when bacteria break down your cat’s pee into ammonia. The faster the litter moisture is absorbed and contained, the less opportunity bacteria have to produce smell.

In my experience, the best cat litter for odour control is one that:

• Clumps quickly

• Prevents urine from spreading through the tray

• Allows easy, regular scooping

Overly perfumed litters can actually discourage cats from using the litter tray. They don’t address the cause of odour. Good clumping and daily scooping are far more effective for keeping odours at bay than an added scent.

This is where many eco friendly cat litter options perform better than expected, especially fibre-based litters that manage moisture evenly.

What are the best types of cat litter for clumping and low dust?

Dust is something I pay close attention to as a vet, particularly for kittens, senior cats, and cats with respiratory sensitivities.

Low-dust litter reduces:

• Inhalation of fine particles

• Tracking around the home

• Irritation to noses and airways

For clumping and low dust, the best-performing types tend to be:

• Tofu cat litter

• High-quality plant fibre blends

• Well-processed paper-based litters
  
  

Traditional clay litters can clump well, but they often produce fine dust, especially as the litter breaks down. Fibre-based litters tend to clump through absorption rather than swelling, which keeps the particles more stable.

The happy medium is balanced clumping, where the litter particles are firm but not rock-hard. This is ideal for both hygiene and comfort.

Where can I buy eco-friendly cat litter in Australia?

More Australians are now searching for where to buy eco-friendly cat litter, especially after they try the product once and discover the difference.

Buying online is the most convenient option, especially as plant-based litters are lighter and designed for home delivery—like our MATCHA cat litter.

A Few More Tips From A Vet

Cat litter might not seem like a big decision at first. But over time, many cat parents realise it has a major effect on their cat’s comfort and overall wellbeing, as well as your home’s cleanliness. This effect is the difference between a manageable routine and a stressful one. 

If you’re wondering which cat litter is safest or which cat litter works best, start by watching your cat. When your cat uses the tray consistently, scooping becomes easier, odours are controlled, and you save time while reducing waste. These are all signs you’ve found the right litter.

The best cat litter in Australia is one that supports your cat’s health while fitting naturally into your life.
