Cats sitting together — a guide to cat litter types and types
Short answer

The main types of cat litter on the market are: bentonite (clay), olive stone, pine pellet, crystal (silica), corn, wheat, tofu and paper (cellulose). These fall into two basic groups: lumps (bentonite, olive pit, corn, wheat, tofu) and those that do not clump (crystal, pine pellet, paper). Four criteria to consider when choosing: dust rate, absorbency, odor control mechanism and cat's paw comfort.

There are dozens of options in the cat litter aisle, and the packaging all claims to be the “best.” In this article, we break down the eight main types and explain who each one is really suitable for.

Two basic groups

Clumping litters

  • The urine becomes a lump and is removed with a scoop.
  • Clean sand remains in the container, extending its life
  • Bentonite, olive pit, corn, wheat, tofu
  • Used with standard litter box

Those that do not clump

  • Urine disperses into sand or evaporates
  • Usually all sand changes more frequently
  • Crystal, pine pellet, paper
  • Some require sieved containers

This distinction directly determines your daily routine. Detailed comparison: clumping or non-clumping?.

1. Bentonite (clay) cat litter

The most common and cheapest option on the market. When sodium bentonite clay comes into contact with water, it swells and forms stone-hard lumps.

Pros: Very strong clumping, low price, easy availability.
Cons: High dust, heavy, mined, not biodegradable, sticks hard layer to bottom of container.

2. Olive pit cat litter

It is produced from olive pits, which are a by-product of olive oil production, and with activated carbon is enriched. Its natural porous structure provides absorbency, and activated carbon provides odor control.

Pros: Dust-free, light, clumping, biodegradable, perfume-free, does not stick to containers.
Cons: The price per kilogram seems higher than bentonite, its lumps are not as rock hard as bentonite.

3. Pine pellet cat litter

It is produced from pressed pine sawdust. When wet, the pellet disintegrates and turns into sawdust; so it usually requires a double-layered container with a sieve.

Pros: Virtually dust-free, biodegradable, natural pine scent, economical.
Cons: Does not clump, large grains are irritating for some cats, special container is required.

4. Crystal (silica) cat litter

It consists of silica gel particles. It absorbs liquid and evaporates moisture over time; Odor control is strong.

Pros: Very high absorbency, strong odor control, lightweight, long-lasting.
Cons: Does not clump, feels hard/sharp under paw, not biodegradable, some cats will not accept it.

5. Egyptian cat litter

A clumping vegetable sand produced from corn cobs or starch.

Pros: Clumping, lightweight, biodegradable, low dust.
Cons: If it gets moisture, it is prone to mold, can attract insects, some cats tend to eat it.

6. Wheat cat litter

A type of sand that clumps with the natural enzymes of wheat starch.

Pros: It clumps, is natural, biodegradable.
Cons: Caution is required in cats with moderate dust, moisture sensitivity, and grain sensitivity.

Detail: wheat cat litter.

7. Tofu cat litter

A sand in pellet form produced from soybean pulp.

Pros: Clumping, low dust, lightweight, biodegradable.
Cons: It deteriorates in a humid environment, its price may be high, and its pellet form is hard for some cats.

Detail: tofu cat litter.

8. Paper (cellulose) cat litter

It is produced from recycled paper. It is very soft and almost dust-free.

Pros: The softest option, dust-free, ideal for the post-operative period.
Cons: Poor odor control, does not clump, saturates quickly.

Detail: paper cat litter, litter after surgery.

Frequently asked questions

How many types of cat litter are there?

The eight main types are: bentonite, olive stone, pine pellet, crystal (silica), corn, wheat, tofu and paper. These are divided into two groups: clumping and non-clumping.

Which cat litter creates the least dust?

Pine pellet and paper-based litters produce the lowest dust. Olive pits and tofu are also in the low dust class. Bentonite is the highest dust producing type.

What are the types of natural cat litter?

Olive pits, pine pellets, corn, wheat, tofu and paper are of vegetable/natural origin and biodegradable. Bentonite is obtained by mining and crystal is obtained synthetically.

Is clumping cat litter better?

For most users, yes, because only the dirty part is thrown away and the clean sand remains in the container. However, non-clumping sand can also be used efficiently with the right container and routine.

What should I pay attention to when changing the type of cat litter?

Make the transition gradually: mix the new sand with the old and spread it over a week. Do not change the location or type of container at the same time.
