Choosing clumping cat litter: how to find the right option without wasting money

A litter tray that starts to smell quickly, clumps that fall apart or dust spreading throughout the room: you soon notice when you have chosen the wrong cat litter. Clumping cat litter can make cleaning easier, but there are major differences between mineral, plant-based and mixed varieties.

Pay particular attention to these three common pitfalls:

• “Strong odour control” does not automatically mean that every smell will disappear. The result also depends on the depth of the litter, daily cleaning, ventilation and the number of cats.
• “Low dust” is not a fixed, universal standard. Fine granules can still spread when the litter is poured or as your cat digs. Always check the usage instructions and product details.
• A firm clump only forms when the litter absorbs enough moisture. A layer that is too thin or an unsuitable scoop can cause urine to stick to the bottom.

What should you look for in cat litter?

1. Clumping and absorption

With clumping cat litter, the composition is key. Bentonite cat litter is known for forming compact clumps when the granules become wet. Plant-based varieties may contain ingredients such as tofu fibres, cassava, maize or tapioca.

Check the following before buying:

• Does the product description state that the litter forms firm clumps quickly?
• Do the clumps remain intact when being scooped?
• Is the recommended layer approximately 5 to 8 cm deep?
• Is the granule structure suitable for your cat-litter scoop?

A product that explicitly states that only the damp part hardens can help keep unused litter clean for longer. However, daily scooping is still necessary to maintain a hygienic litter tray.

2. Odour control without an overpowering scent

When looking for cat litter for odour control, you will often see terms such as activated charcoal, bicarbonate of soda or deodorising ingredients. According to g’woon’s product description, activated charcoal is combined with bentonite. Some plant-based varieties mention bicarbonate of soda.

These are verifiable ingredients, but how well they work in your home can vary from one situation to another. A scented variety may also be unpleasant for some cats. If you are unsure, choose unscented cat litter and place the tray somewhere dry and well ventilated. Remove faeces and urine clumps daily, and replace the entire contents according to the label.

3. Dust, tracking and automatic litter trays

Low-dust cat litter can help keep the area around the tray cleaner, but granule size is also important. Fine granules feel natural to many cats, but they can stick to their paws more easily.

For an automatic litter tray, the following points are important in addition to clumping:

• The clumps must be firm enough not to fall apart during the mechanical process.
• The granules must not be too heavy or too large for the screening system.
• The manufacturer must explicitly state that the product is suitable for automatic litter trays.
• Check whether the tray uses a front-scooping or another specific system.

Do not flush used litter down the toilet unless the label explicitly permits it. Plant-based or biodegradable cat litter should generally also go in general waste. Local waste-disposal rules may vary.

Which type is right for your household?

• Bentonite: often suitable when firm clumps and heavier granules are important.
• Tofu cat litter: a plant-based option with lightweight fibre granules; check its dust levels and suitability for your tray.
• Cassava cat litter: often combined with maize, wheat or other plant-based raw materials.
• Mixed litter: combines, for example, bentonite with tofu or cassava and can offer a middle ground between clumping, weight and choice of material.
• Non-clumping litter: such as Catsan Hygiene, which absorbs moisture without forming urine clumps. This requires a different cleaning routine.

A plant-based composition may appeal to anyone looking for eco-friendly cat litter, but “plant-based” alone says nothing about dust, tracking or waste disposal. Always check the full ingredients list.

Practical tips for reducing waste

1. Fill the tray to the recommended depth and top it up after scooping.
2. Scoop at set times each day. This keeps urine clumps smaller and leaves more unused litter in the tray.
3. Use a mat underneath the tray to reduce tracking, especially with fine plant-based granules.
4. Store an opened bag somewhere dry and tightly sealed. Moisture can affect clumping even before use.
5. Switch gradually to new cat litter by mixing it with some of the litter your cat is used to.

Frequently asked questions about clumping cat litter

How often should you replace clumping cat litter?

Remove faeces and urine clumps daily, and top up as needed. The entire contents should usually be replaced and the tray cleaned every two to four weeks, depending on the number of cats, the size of the tray and the product instructions.

Which cat litter produces little dust?

Look for a product described as having a low-dust or dust-reducing formula. Plant-based tofu and cassava varieties can be lightweight, but fine granules can still spread as your cat digs. Pour new litter into the tray slowly and consider using a mat underneath.

Is clumping cat litter suitable for an automatic litter tray?

This varies from one device to another. Only choose a product whose product information mentions automatic litter trays, and compare granule size, clump strength and the type of screening system. According to the product description, Photonspace Tofu & Cassava is suitable for compatible traditional and automatic litter trays; always check this against your device’s manual.
