Cat litter: how to choose the right solution for odours, maintenance and your pet’s needs

A cat litter has to tick several boxes at once: absorb quickly, control odours, feel comfortable under paw and be easy to clean. With all the marketing claims and differences in materials, the choice can quickly become overwhelming.

Common pitfalls before you buy

1. Confusing “biodegradable” with “compostable”

A plant-based cat litter can be made from tofu, wheat, maize or cassava. That doesn’t automatically mean it can be flushed down the toilet or put in a home compost bin. Whether you can dispose of it that way depends on the quantity, your plumbing system and local regulations.

Always read the manufacturer’s instructions. Even when a tofu litter is described as biodegradable or compostable, it’s best to flush only very small amounts, and only if local rules and your plumbing allow it. Mineral litters and crystal litters should generally not be disposed of through the drains.

2. Choosing an odour-control litter just because it’s scented

A fragrance can mask odours without tackling the moisture problem. Some cats may also turn their nose up at a tray that smells too strong. For sensitive pets, an unscented formula combined with good absorption and daily removal of waste is often a better choice.

A litter tray deodoriser can help with maintenance, as long as it’s compatible with the tray you use. Check whether it’s a refill, a gel or an accessory designed for a specific model.

3. Relying on a low-dust claim without checking the granules

The amount of dust depends on the material, the size of the granules, how the litter is transported and how you pour it. Even a formula marketed as a dust-free cat litter or low-dust should be handled gently in a well-ventilated area. For a kitten, also look at the granule size to reduce the risk of accidental ingestion.

Key factors to check before you choose

Clumping or non-clumping?

Clumping cat litter forms a solid lump when it comes into contact with urine. This lets you remove the soiled areas each day while keeping the rest of the tray contents. Tofu fibres, wheat and certain mineral formulas fall into this category.

Non-clumping mineral litter absorbs moisture throughout the whole tray. You need to remove solid waste daily, stir the granules as the manufacturer recommends, and then replace all the litter once the material is saturated. This type can suit households that prefer a simple routine and larger pack sizes.

Material and paw comfort

  • Tofu, maize, cassava or wheat: plant-based litters are often chosen for their renewable origin and their ability to form clumps.
  • Clay, chalk or quartz: a mineral litter can offer consistent absorption, but you’ll need to consider its weight and how to dispose of it.
  • Silica crystals: crystal litter absorbs moisture and generally requires less material to be removed. However, it must be used with a compatible tray and should not be flushed down the toilet.

For a kitten litter, choose a texture that your young cat will readily accept, and keep an eye on their behaviour during the first few days. A gradual transition reduces the risk of them rejecting the tray.

Depth, maintenance and tray capacity

Manufacturers often recommend a layer of 5 to 7 cm, with some instructions going up to 10 cm. A layer that’s too thin will quickly reach the bottom of the tray, while one that’s too thick uses more litter and can get kicked out.

Remove solid waste and clumps every day, then give the tray a full clean following the manufacturer’s instructions. In a multi-cat household, plan for more frequent changes and, if possible, provide several separate trays.

Urine detection and automatic devices

A litter with urine blood detection can serve as a visual indicator. If the granules change colour, this is not a diagnosis: contact your vet promptly and follow the instructions supplied with the product.

A self-cleaning litter tray can reduce how often you need to scoop, but it comes with several requirements: a power supply, sensor maintenance, dedicated consumables and strict compatibility with the type of litter. Before you buy, also compare the cost of refills.

Frequently asked questions about cat litter

How much litter should you put in a tray?

A layer of 5 to 7 cm is a good starting point for clumping and plant-based litters. Some mineral litters recommend a depth of 5 to 10 cm. Check the packaging, then adjust the amount to suit the size of the tray, your cat’s habits and how often you clean.

How long does a litter last?

How long it lasts depends on the number of cats, the tray size, the type of granules and how much you remove each day. A clumping litter is topped up as you go, while a non-clumping formula needs to be replaced once it’s saturated. Automatic devices reduce scooping, but they still require consumables and regular maintenance.

How can you reduce odours without upsetting your cat?

Remove waste every day, clean the tray regularly and place it in a quiet, well-ventilated spot that’s easy for your cat to access. If your cat is sensitive to strong smells, choose an unscented odour-control litter. You can add a compatible deodoriser, but always check the specific model and safety instructions.
