"Plant-based" covers a wide range of cat litters. Tofu, pea fibre, corn, wheat, wood, paper and grass litters are all made from plant material, but they behave quite differently in the tray. Here's how the main types compare, and what to check before you choose one.
What counts as plant-based cat litter?
Plant-based litters are made mainly from plant materials or by-products, rather than mined clay or silica. The base material affects how the litter clumps, how much it weighs, how it handles odour and moisture, and how you can dispose of it. Two litters made from the same plant can also perform differently, because the processing, granule size and added ingredients vary between brands.
The main types at a glance
| Type | Typical form | Clumping | What people like | Things to check |
|---|---|---|---|---|
| Tofu / pea fibre | Small pellets or fine granules | Usually clumping | Light to carry; many are low-dust | Some cats need time to adjust to the texture; check disposal instructions |
| Corn | Granules | Often clumping | Soft texture; scoopable | Keep dry and stored as directed |
| Wheat | Granules | Often clumping | Natural starches help clumping | Some can be softer when wet; check storage guidance |
| Wood (pine etc.) | Pellets or shavings | Pellets usually non-clumping; some clumping wood litters exist | Natural wood scent; widely available | Pellets break down to sawdust; usually need a sifting tray |
| Paper | Pellets | Usually non-clumping | Very soft; often suggested after surgery | Absorbs, but doesn't clump; changed more often |
| Grass / walnut / other | Varies | Varies | Alternatives if other types don't suit | Fewer options, more variation between brands |
These are general patterns, not rules. Always check the individual product.
Tofu and pea fibre litter
"Tofu" litter is a broad name for litters made from soybean or pea fibre, often by-products of food production. Most are formed into small pellets or fine granules and clump when wet. They're typically lighter than clay, and many are designed to be low-dust.
Cats that are used to clay may notice the different feel, so a gradual switch helps. Disposal varies by product, so follow the manufacturer's instructions (see the disposal section below).
Our Original is a pea fibre-based clumping litter with no added fragrance. Its formula also includes enzymes intended to help break down odour at the source, plus activated charcoal and baking soda.
Corn litter
Corn litters are usually made from ground corn or corn cob. Many clump, and some cats like the soft texture. As with any food-derived litter, storage matters: keep the bag sealed and dry, and follow the manufacturer's storage guidance.
Wheat litter
Wheat litters use the natural starches in wheat to help them clump. Performance varies quite a bit between brands. Some are firm, while others can soften if the litter stays damp. Daily scooping helps.
Wood litter
Wood litters are often made from pine or other softwoods, usually as compressed pellets. Most pellet litters don't clump. Instead, they absorb liquid and break down into sawdust, which is why many owners use them with a sifting tray. Some people like the natural wood smell. Some cats dislike the hard feel of pellets under their paws, so it's worth trying a small amount first.
How to choose between plant-based litters
- Clumping or non-clumping? Clumping litters make it easy to remove waste and keep the rest of the tray in use. Non-clumping litters usually need a full change more often.
- Your cat's preferences. Texture and granule size matter to many cats. If your cat is happy with a fine, sandy litter, a fine-granule plant litter may be an easier switch than large pellets.
- Dust. If dust is a concern for you or your cat, look for litters designed to be low-dust, and pour gently.
- Odour. Look at how the litter is designed to manage odour. Fragrance, activated charcoal, baking soda and enzymes are different approaches. Daily scooping matters with any litter.
- Automatic litter boxes. If you use one, check your machine maker's litter guidance first. Suitability depends on the specific litter and the specific model.
- Disposal. Check what the manufacturer says, and what your local council allows.
A note on disposal
Plant-based doesn't automatically mean flushable or compostable. Many Australian water authorities ask people not to flush anything except pee, poo and toilet paper, and used cat litter contains cat faeces, which can carry parasites such as Toxoplasma. Unless the manufacturer and your local authority say otherwise, bag used litter and put it in your general waste bin.
Switching to a plant-based litter
If your cat is used to clay or crystal litter, mix the new litter in gradually over about a week, or longer for a cautious cat. Keep the tray clean, change one thing at a time, and watch how your cat responds. If your cat's toileting changes suddenly, or you notice straining, blood or very little urine, see your vet. A cat that can't pass urine is an emergency.
