Cat litter: how to choose the right type and size, and avoid nasty surprises

Choosing cat litter seems simple… until odours start to linger, granules end up all over your home or the bag runs out far sooner than expected. The claims on the packaging aren’t always enough to help you compare products. The litter’s composition, how easy it is to clean and the pack size all directly affect your cat’s comfort, as well as your household budget.

Common pitfalls when buying cat litter

1. Confusing absorption with clumping

Absorbent litter holds moisture, but doesn’t necessarily form clumps. Clumping litter, usually made from clay or plant fibres, gathers liquids into clumps that you can scoop out. This helps keep the rest of the tray clean for longer.

By contrast, non-clumping mineral litter or silica litter often requires you to remove faeces every day and check the overall condition of the litter regularly. The right choice therefore depends more on your routine than on the length of use claimed on the bag.

2. Assuming ‘odour control’ means no smells at all

Odour-control cat litter may contain activated charcoal, fragrance or a particularly absorbent material. However, no product means you can skip regular waste removal, good ventilation or choosing a tray that’s large enough. Activated charcoal is used in several Biokat’s products, for example, but it should be seen as a product feature rather than a guarantee that will work in every situation.

Fragrances don’t suit every cat, either. An unscented formula, such as natural cat litter made from unscented clay, may be a better choice if your pet is sensitive to changes in smell.

3. Choosing a bag based on volume alone

A 5 L, 8 L, 14 L or 18 L bag of cat litter doesn’t always make it easy to compare the cost per use. Density varies depending on whether the litter is made from clay, paper pellets, plant fibres or silica. Lightweight litter may take up more space, while mineral litter is often heavier to carry.

If you have several cats, also check how often the litter should be replaced, how deep it needs to be in the tray and whether you have somewhere dry to store the bag.

Technical features to check

Composition and texture

  • Clay or bentonite: widely used in clumping litter, it forms compact clumps but can create dust when you fill the tray.
  • Silica: its crystals hold moisture and are generally lightweight. However, silica litter doesn’t necessarily form clumps.
  • Plant fibres: these can be used to make biodegradable litter with a lighter texture. Always check your local disposal guidelines.
  • Recycled paper: its pellets are often low-dust and easy to carry, but are generally non-clumping.

Be wary of claims that litter is dust-free. Look for wording such as ‘low dust’ and check the manufacturer’s detailed product information. Pour the litter slowly and ventilate the room.

Odour control

Activated charcoal, absorbent minerals and some plant-based materials can help reduce odours. A scented formula, such as some products in 10 L or 18 L sizes, adds a fresh fragrance, but may not suit every pet.

For everyday use, look for litter that makes it easy to remove soiled areas. The shape and firmness of the clumps, and whether they tend to stick to the bottom of the tray, are all useful things to check.

Cleaning, safety and disposal

Fill the tray according to the manufacturer’s instructions, usually to a depth of 2 to 7 cm, depending on the material. Remove faeces every day and take out soiled clumps as soon as possible. When you replace all the litter, clean the tray with water and a mild detergent.

Don’t flush used litter down the toilet unless clear local guidance confirms that the product is suitable for this. Pregnant or immunocompromised people should generally avoid contact with soiled litter or wear gloves, then wash their hands thoroughly.

Frequently asked questions about cat litter

How much litter should I put in the tray?

The depth depends on the type of litter and the manufacturer’s recommendations. Clumping mineral litter often needs a 5 to 7 cm layer, while some plant-based pellets can be used in a thinner layer. If the layer is too shallow, it reduces absorption and makes litter more likely to stick to the bottom of the tray.

Which litter should I choose to reduce odours?

Choose an easy-to-clean clumping formula, optionally with added activated charcoal. Silica litter can also hold moisture, but works differently and may not suit every cat. Whatever type you choose, remove waste every day and follow the recommended replacement schedule.

Can biodegradable litter go in the compost?

It depends on its composition and the rules in your local area. Some paper or plant-fibre litters are described as compostable, but soiled waste shouldn’t automatically be added to compost intended for growing food. Check the packaging and local guidance before disposing of it.
