The Best Cat Litter To Buy For Indoor Cats – Updated 2022

Cat litter boxes, especially for indoor cats, are an essential element of keeping your cats in a healthy, stress-free environment. Cats are meticulous cleaners, so keeping their litter boxes as clean and fresh as possible will help them avoid unnecessary stress and toilet issues, which can lead to more serious problems. The cat litter you use is a crucial component of this, and today we’ll look at some of the best cat litter for indoor cats. There are a plethora of brands to choose from, all constructed of different materials and each with its own set of advantages and disadvantages.

The number of litter boxes in the house should, in general, be more than the number of indoor cats (so 3 litter boxes for a 2 cat household). To keep your cat happy, scoop and refill the litter boxes at least once a day, or more frequently if necessary. Some cats (including ours) will not enter a litter box containing waste, and who can blame them?

At least once a week, old litter should be entirely replaced with fresh cat litter, and this is also a good time to clean up your litter boxes. Remove all of the soiled litter and give the litter boxes a thorough cleaning with warm, soapy water. You can buy cat-safe cleaning products for this, but we don’t think they’re necessary; avoid using strong bathroom cleaners like bleach, as anything with a strong chemical content or even smell can be off-putting to your cat.

The Best Cat Litter To Buy For Indoor Cats

World’s Best Cat Litter

Worlds Best Cat Litter 28lb (12.7kg) Multiple Cat Unscented
  • OUTSTANDING ODOR CONTROL — More cats shouldn’t mean more smells — keep your cats happy with a natural litter with long-lasting odor control.
  • QUICK CLUMPING & EASY SCOOPING — Multiple cats can most often mean more clean up — but not with this fast-acting natural litter that requires no chiseling or scraping.
  • LIGHTWEIGHT, 99% DUST FREE & FLUSHABLE - SEPTIC SAFE — Naturally free of silica dust, this lightweight cat litter offers low tracking and less mess — and is tested and proven flushable and safe for septic and sewer systems.
  • PET, PEOPLE & PLANET FRIENDLY — A naturally safe litter made from whole-kernel corn that offers no harmful chemicals and no artificial perfumes.

This kitty litter is exceptionally successful in odour management and smells lovely thanks to natural scent absorption chemicals. As a result, it’s perfect for an indoor cat because it won’t stink up your home or apartment!

When combined with waste, World’s Best Cat Litter makes little clumps that are easy to sweep up and do not stick to the box’s sides or bottom. Furthermore, the clumps are fully water-soluble and may be flushed away. There will be no more plastic bags! We observed a significant difference between this litter and another “rapid clumping” litter when we first tried it. World’s Best Cat Litter clumped rapidly and converted urine into neat little balls that were easy to scoop up – and didn’t break apart!

We noted a long-lasting freshness while testing this litter and can attest to the company’s 99 percent dust-free assurance. Furthermore, the litter has a really velvety feel, which our cat adored. Coco was more thrilled to dig and scratch with this litter than with prior litters, and she did it without injuring her paws.

There are no chemical additions or scents in World’s Best Cat Litter. Even when consumed, it is not harmful to cats and kittens.

Our recommendation for using this product is to spread a 5–7 cm layer evenly over a clean and dry litter box. The company warns against mixing their product with others because it could damage its performance.

What we liked about it:

created from a renewable natural resource

water-soluble and biodegradable (flushable)

there are no chemical additives

clumping that is particularly strong

highly cost-effective

99% dust-free


odour absorption to the maximum

Gentle on paws

Cats seem to like it

Even when eaten, cats and kittens are not harmed.

suitable for cats with allergies

What we didn’t like about it:

To be quite honest, not much! The cost is higher than the litters sold in supermarkets. However, because of its efficient clumping and scent absorption, you end up using less litter. We were able to save money after doing the calculations.

Pettex Pampuss Woodbase Cat Litter

Pettex Pampuss Woodbase Cat Litter 30 Litre
  • Pine fresh
  • Highly absorbent
  • Light to handle
  • Easy to dispose of
  • Made from recycled materials

This cat litter is 100 percent natural and biodegradable, as it is created from repurposed wood (compressed sawdust). It also has a natural pine scent, which is a huge plus when looking for the best cat litter for indoor cats. Our kitty enjoyed using this litter because it had a natural scent rather than dust or an artificial scent. It also keeps your cat’s litter box smelling clean and fresh, which is excellent in a small space.

When it came to passing the usage test, the wood pellets decomposed into a mushy, odourless substance. Because it’s a non-clumping litter, it’s no surprise that the Pettex Pampuss Woodbase Cat Litter didn’t do much to mask the odour of poo. It is, however, a long-lasting choice for your indoor cat if cleaned frequently as per our recommendations.

Overall, it’s a good litter that gets the job done. What we liked best was how inexpensive it was, with a 30L bag costing roughly £10.00. There aren’t many high-quality or natural cat litters that can compete with that kind of price.

Pampuss Wood cat litter from Pettex is designed to replace your old cat litter. By alternating the two, you may gradually phase out the old cat litter. You should only use this product after a few tweaks.

What we liked about it:

Wood pellets with a high absorbency absorb two times their weight.

Natural materials are used exclusively.

pine scent (natural)

made of reclaimed wood

low quantities of dust

It’s easy to handle and dispose of.

materials that are biodegradable

smells are naturally controlled

ideal for kittens and cats

What we didn’t like about it:

It does not clump.

Catsan Hygiene Litter

Catsan Hygiene Cat Litter 20L
  • Catsan Hygiene Plus Litter is a good choice for you and your feline friend, thanks to the active ingredients which prevent the growth of bacteria, helping your cat litter tray stay hygienic
  • Each granule of Catsan Hygiene Cat Litter ensures reliable and long lasting odour control, absorbing liquids and locking away moisture before odours can develop
  • Catsan Hygiene Cat Litter has very low dust when poured out of the bag, and ensures long lasting odour control without the addition of fragrances that might upset your cat
  • Cleanup is easy and simple with Catsan Hygiene Cat Litter, to ensure that your feline friend stays clean and healthy, remove the solid faeces daily for continued odour control and a clean environment
  • Items delivered: Catsan Hygiene non-clumping Cat Litter for adult cats and kittens 20 l

We got a lot of white dust filling the air while emptying the bag into a litter box because it was composed of natural stone that rubs together in the bag. This, however, rapidly subsided, and there was no need to clean anything.

You can count on Catsan to keep your home feeling fresh and clean. The natural mineral content, according to the business, prevents odour development three times more effectively than other typical cat litters, making this one of the best.

This Catsan Hygiene Litter isn’t a clumping cat litter in practise. As a result, the faeces was not entirely covered, and the odour was not trapped. However, this makes scooping it up easier, and any small clean particles fall through the litter scoop, resulting in a limited amount of cat litter being removed.

Due to the fact that it is not a clumping cat litter, it is impossible to remove all of the urine-soaked particles. Catsan’s litter, on the other hand, absorbs liquids exceedingly well and retains the aroma as stated.

A clay layer formed at the bottom of the litter box after about a year of use, made comprised of white dust that bonded when exposed to moisture. It has been demonstrated that removing it is impossible (even using a pressure washer). However, this isn’t a complete disaster! When the tray is full of litter, the layer doesn’t smell and can’t be seen.

Apart from the aforementioned reasons, this litter didn’t make it to the top of the best cat litter list because little white particles became lodged in our cat’s paws, causing Coco to kick out litter outside of the litter box, necessitating extra cleaning.

Despite a few drawbacks, Catsan Hygiene Litter remains our second pick. It’s of excellent quality, is reasonably priced, and performs admirably.

What we liked about it:

odour control that’s second to none

appearance that is hygienically white


quickly absorbs moisture

prevents the growth of bacteria

Smart Packs are really simple to use.

ideal for kittens and cats

What we didn’t like about it:

Smell control isn’t perfect

When emptying the bag, there was a lot of dust.

Okoplus Cats Best Original Clumping Cat Litter

No products found.

Okoplus Cats Best Original Clumping Cat Litter is natural, biodegradable, and compostable, much like many of the other options. Cats Best claims to be the only clump-forming biodegradable wood-based cat litter on the market. If you’re ecologically minded, you’ll get a lot of brownie points!

Okoplus Cats Best Original Clumping Cat Litter, for example, is comprised entirely of organic plant fibres that link together to form clumps that trap odours inside. The best thing about biodegradable cat litter is that you can flush the clumps down the toilet, which is a huge plus because you won’t have to waste a single plastic bag every day.

Another advantage is that Cats Best comes in a variety of sizes, including 4.3kg (10L), 8.6kg (20L), and 13kg (30L), all at affordable costs, so you don’t have to wait to try “Europe’s number one cat litter”!

This cat litter’s natural fibres are extremely good in holding liquids. As a result, clumps may be removed and Okoplus Cats Best Original Clumping Cat Litter can be used more sparingly. Because it is so excellent at retaining fluids, it has above-average odour management and will keep your indoor litter smelling fresh for longer.

Cats Best states that this litter can be used for up to 7 weeks thanks to their highly refined wood fibres. For you, this means fewer effort and cheaper expenditures.

However, we discovered that the litter adhered to Coco’s paws and she left the litterbox more than the other four options. If you plan to use Cats Best Okoplus, we recommend installing a litter tray mat to trap the particles and prevent litter from spreading around your home. On Amazon, we recommend Trixie Cat Litter Tray Mat. A little mat costs roughly £5, whereas a larger mat costs £11.

What we liked about it:

100% natural wood and plant fibres

odour binding that works

It can absorb up to 7 times its own volume


biodegradable and compostable


ideal for kittens and cats

What we didn’t like about it:

It has a habit of spreading outside of the box

Indoor Cat Litter Buying Guide & FAQs

Why Use Cat Litter?

Cats are normally highly clean animals, and they have had this inclination since birth. Cats in the wild will strive to bury their faeces in a clean manner, usually under sand or mud. There are two reasons for this. To begin with, cats utilise their pee and faeces to mark their territory, with more subordinate cats burying their waste so that more dominant cats do not feel threatened. Your cat buries his or her waste partly to show that he or she recognises you as the house’s dominant cat. The major reason, though, is to avoid attracting unwelcome attention from wild animals. Burying their faeces conceals their odour and keeps them hidden from discovery.

Cat litter encourages cats to pursue their natural instincts when they are within our houses.

Where Should a Litter Tray Go?

Cats are particular about where they go to the bathroom and prefer solitude, so put their litter box in a safe, out-of-sight location in your home. The tray should never be placed near their food or water bowls, nor should it be placed near where they sleep. This is actually fairly reasonable — would you like a toilet next to your bed or in your kitchen?

A covered litter tray provides more privacy for some cats, while an open litter tray is preferred by others.

While cats are generally tidy creatures, accidents sometimes occur, so the litter pan should be placed on a clean, easy-to-clean floor that can be wiped clean if necessary.

If you place the tray in a room with underfloor heating, you may wish to put something insulating between the floor and the tray, such as a foam board, to prevent bacterial growth and an unpleasant odour.

How Much Litter Should There Be In The Tray?

It’s best to fill the litter box to a depth of 5-7cm with most cat litters (2-3 inches). Depending on the type of litter, this may vary significantly, but most packaging will specify how much to use.

There should be enough litter in the tray for your cat to bury their excrement and absorb their pee, preventing it from accumulating at the bottom.

How Often Should Cat Litter Be Replaced?

Remove solid waste every day and replenish litter every 4-5 days/weekly if you’re using non-clumping litter.

Remove solids and clumps from clumping litter on a daily basis and refill with the same amount of litter. Although the litter does not need to be replaced as frequently as non-clumping litter, it is still a good idea to do so on a regular basis — usually once a month.

What Is the Best Way to Clean the Litter Tray?

It’s a good idea to clean the tray as well while replacing the litter. Use hot water and a detergent that has no strong odours. Cats have a keen sense of smell, so any cleaning product with a strong chemical odour will likely repel them. Also, stay away from any cleaning products with vinegar components. This is because vinegar additives have a strong odour that is comparable to cat urine, causing your cat to avoid the tray. If you use a disinfectant, make sure it doesn’t contain Phenol (Carbolic Acid), which is extremely hazardous to cats.

How to clean your cat’s litter tray

How Do You Get Rid of Cat Litter?

Scooping cat litter into a biodegradable poop bag and placing it in your regular home bin or a cat litter bin is the best way to dispose of it.

Even though the litter is labelled as flushable, you should not flush cat litter or cat excrement down the toilet.

More information on the best approach to dispose of cat litter and why not flush cat litter may be found in our blog postings.

What is the Best Litter for Your Cat?

If you’ve recently adopted a new cat or kitten, they’re likely to be accustomed to a specific type or brand of litter, so it’s frequently preferable to stick with that for the time being. If you’ve recently acquired or purchased a cat or kitten, find out what kind of litter they were used to from their previous owner.

The ideal litter for your cat is determined by a lot of factors, including your cat’s hair length, whether they have sensitive paws or allergies, your budget, and how much time you have to keep their litter box clean.

However, it may take some trial and error to locate the best litter for them, as they may not like the brand you initially purchase. One idea is to put different types of litter in different trays and observe which one they prefer. Some litters come in smaller trial packs, which are a fantastic opportunity to explore a variety without having to invest in the bigger, more expensive bags.

Another option is to introduce a new litter type gradually, rather than replacing it completely at once, by adding it to the existing litter little by little.
