Choosing the right cat litter is more important than most cat owners realise. The wrong litter can cause your cat to avoid the litter box entirely — one of the most common behavioural issues that leads to cats being surrendered to shelters. Getting this right from the start makes life cleaner and more harmonious for everyone.
Types of Cat Litter Available in Australia
Clumping Clay Litter
The most widely used litter in Australia. Fine clay particles clump around urine for easy scooping. Excellent odour control. Dust levels vary by brand — look for low-dust formulas to protect respiratory health in cats and owners with allergies. Heavy to carry in bulk.
Non-Clumping Clay Litter
More affordable but requires full tray changes rather than spot-scooping. Less popular for indoor cats. Some cats prefer the coarser texture.
Silica Crystal Litter
Absorbs urine and desiccates solid waste. Very low dust. Long-lasting — a single tray fill can last weeks. More expensive upfront but economical long-term. Some cats dislike the texture on their paws.
Recycled Paper Litter
Made from recycled paper pellets. Low dust, biodegradable, and recommended for cats recovering from surgery as it doesn’t stick to wounds or incisions. Less effective odour control than clay or crystal. Popular in Australian households with respiratory sensitivities.
Wood/Pine Litter
Made from compressed wood shavings or pine pellets. Natural pine scent provides good odour control. Biodegradable and compostable. Pellets break down into sawdust when wet — requires a sifting litter tray for effective use.
Tofu/Plant-Based Litter
A newer category gaining popularity in Australia. Made from soy byproducts — biodegradable, flushable (in small quantities), very low dust. Gentle on sensitive paws. Good clumping. Price point higher than traditional clay.
What Cats Prefer: The Science
Multiple studies confirm that the majority of cats prefer fine-grained, unscented, clumping litter — most closely resembling the sand or soft earth they would choose in nature. Avoid strongly perfumed litters — a cat’s sense of smell is 14 times stronger than ours, and perfumes that seem mild to us can be overwhelming and aversive to cats.
Litter Tray Setup Tips
- Number: One tray per cat, plus one extra (the n+1 rule)
- Size: The tray should be 1.5x the length of your cat — most commercially available trays are too small
- Location: Quiet, accessible location away from food and water bowls and laundry appliances
- Depth: At least 5cm of litter — cats prefer to dig and cover
- Covered vs uncovered: Most cats prefer uncovered trays for ventilation — covered trays trap odours inside where the cat has to sit with them
Frequently Asked Questions — Cat Litter Australia
How often should I change cat litter?
Scoop solids and clumps daily. Top up litter as needed to maintain the 5cm depth. Do a full tray clean and litter replacement every 1–4 weeks depending on the number of cats and litter type used.
Is clumping cat litter safe for kittens?
Most vets recommend using non-clumping litter for kittens under 4 months as young kittens may ingest litter during grooming. Once the kitten is past the mouthing/exploring stage, clumping litter is generally safe.
Why is my cat not using the litter box?
Common causes: litter box too dirty, wrong litter type or texture, box in a stressful location, box too small, medical issue (urinary tract infection, crystals, arthritis making entry difficult). If your cat suddenly stops using the litter box, a vet check is always the first step.
