This really comes down to what you – and perhaps more importantly your cat – prefers. The only exception to this is if you have a kitten, in which case we’d always recommend non-clumping litter. This is because kittens sometimes eat their litter (and anything else they can sink their inquisitive little teeth into!) and clumping litter could clump in their stomach.

Assuming you’ve got an adult cat, the biggest difference between clumping and non-clumping litter is the cleaning routine. Non-clumping litters, such as Catsan™ Hygiene litter, absorb a large volume of liquid. This means, as long as you remove faeces daily, the litter tray will stay fresh for approximately a week. Once a week, you’ll need to empty the litter tray completely and fill it with new litter.

Clumping litter, such as Catsan™ Ultra Plus litter or Catsan™ Natural clumping litter, forms a clump around urine or faeces so that you can easily remove that instead of having to empty the entire litter tray (don’t forget to keep the litter topped up to make up for the clumps you’ve removed). This can mean less frequent thorough cleaning, although it’s important to remember that cats are scrupulously clean and will expect their litter tray to be too!

Aside from cleaning, the other main differences a cat parent will notice is that non-clumping litter, being porous, is lighter. This is convenient when you’re out shopping, but it does mean the litter comes out of the tray slightly more easily when your cat digs. Clumping litter is heavier to carry but more likely to stay in the litter tray.

We’ve spent four decades perfecting our ‘recipes’ and are proud of the high-quality, natural ingredients we use. These vary across the range. Catsan™ Hygiene litter, for example, is made with lime and white quartz, and Catsan™ Natural litter is made with a by-product of wheat milling that would otherwise go to waste.

At Catsan™, we don’t believe in adding harsh substances such as biocides or antibacterial agents to our litters. Instead, we design them to make them as unattractive to bacteria as possible – which of course makes them very attractive to your scrupulously clean cat!

Catsan™ Natural clumping litter is 100% biodegradable and 100% compostable.

Almost all our products (98%) come in paper bags that you can easily just pop into your paper recycling. The only exception is the Catsan™ Smart Pack™, and we’re working hard to make sure we keep the same great product but also make sure it’s recyclable. We’re committed to do this by the end of 2025.

As cats have such high standards of cleanliness, they’re likely to love Catsan™! However, because they’re somewhat fussy creatures who tend to get set in their ways, it’s important to make the change gradually. This means mixing in the new litter with some of the unsoiled old litter over a period of several days. This gives your feline friend time to adjust.

Cat faeces can be dangerous for pregnant women, so the advice from the NHS is that they should avoid changing cat litter if at all possible. If you have to do it, wear a mask and rubber gloves and wash your hands very thoroughly afterwards.

The good news is, because Catsan™ litters are high-performing and long-lasting, there’s less to dispose of over time.

If you use Catsan™ Hygiene Plus litter, Catsan™ Smart Pack™ litter, Catsan™ Ultra litter, it’s best to just pop it in your regular household waste.

If you use our biodegradable litter, Catsan™ Natural clumping litter, we recommend that you put it in your communal bio waste where local regulations allow. We don’t recommend putting litter into private compost bins as these normally don’t get hot enough to kill all the possible bacteria and parasites in cat faeces.

While technically feasible, we also wouldn’t recommend flushing Catsan™ Natural Clumping litter down your toilet. This is because, just like other ‘flushable’ litters, it uses water unnecessarily and puts a strain on waste water treatment.
