What Is Wood?

According to the Merriam-Webster Dictionary, “wood” is…

“…the hard fibrous substance consisting basically of xylem that makes up the greater part of the stems, branches, and roots of trees or shrubs beneath the bark and is found to a limited extent in herbaceous plants.”1 Wood Definition & Meaning – Merriam-Webster

Wood is in everything from houses to golf clubs and is a common fuel for heating and cooking.

What Is Wood Cat Litter?

wood pellets, litter

Wood cat litter is sawdust and scraps of various types of wood left over from the lumber industry.

The type of wood is whatever’s available, which is almost always hardwoods (pine is an exception).

Cedar, cypress, pine, Douglas fir, and aspen are examples of wood you can find in litter, either in granular (crumble) or pellet form.

Manufacturers heat it “to 1200°F (649°C) in a kiln-type vat.”2 How cat litter is made – material, production process, manufacture, used, product, industry, machine (madehow.com)

This makes the tree sap act like glue and bonds everything together as it goes through a screen and becomes pellets, then cooled in a tank and packaged.

Crumble is softer than pellets but basically the same.

How Does It Work?

cat litter pellets, wood

Wood cat litter absorbs liquid and odors, then falls apart into dust.

This works well in sifting boxes, where the wood dust falls through to the bottom while the unused pellets stay in the top, making it easy to clean.

Clumping vs. Non-Clumping

Wood cat litter pellets aren’t clumping, since they disintegrate into powdery sawdust.

Manufacturers add clumping agents, such as guar bean gum, to the softer granular crumble litter.

It clumps but they tend to be softer than clumps of clay and other litters, which makes them fall apart easily.

Some people might prefer clumping even if it doesn’t make hard clumps like clay.

They already use clumping litter, prefer to scoop everything, and might not want to sift the litter.

Cats may also prefer the softer feel, especially if they’re declawed, arthritic, or have other sensitivity issues.

Don’t mix pellets with clumping litter because each works against the other.

The pellets won’t absorb properly, and the clumps won’t form well.

Pros & Cons of Wood Cat Litter

What are the pros and cons of using wood cat litter?


  • Pellets don’t track as much as finer grain litters
  • They’re less dusty, which is better for people (and cats) with asthma or dust allergies
  • Wood litter is more economical than clay because it lasts longer, and you don’t throw as much away when cleaning.

  • Pine has natural properties that help control odors
  • Some companies include ingredients that help create clumps in crumble (granular) litter

As with all litter, your cat has to love it too.

  • One problem with pine litter is that cats don’t like strong odors… and pine is strong-smelling!
  • It may not be possible to convince your cat to accept it
  • Your cat may not like the hard pellets, but might be ok with softer granules (crumbles) which can cost more

  • Pellets are hard and even though they don’t track as much, they still escape the box, especially if you have a wild litter flinger. You know what I mean if you’ve ever stepped on them in bare feet!
  • If you’re using a regular litter box, it can take longer to clean if you’re trying to save pellets. It’s easier to use pine pellets in either a manual or automatic sifting litter box.
  • Wood can attract bugs, but if you see bugs near or in pine litter it means the bugs were already in the house and you should call an exterminator.

The pellets are economical because you don’t have to throw away unused ones while trying to get rid of the soiled ones.

People who use wood cat litter like that it’s lighter weight than clay and lasts longer.

Some wood like cedar and pine has natural properties that help control odors… helpful for controlling pee smells in cat litter.

Note that nothing controls the odor of poop. Scoop-and-flush is the only way to get rid of it!

If your cat’s poop is abnormally stinky, it’s time for a vet visit. This could be a sign of a medical condition.

Is Wood Litter Biodegradable?

Yes, wood cat litter is biodegradable… you can use it as mulch, especially on areas where soil needs to be more acidic.

It’s best, though, to put it only on flower beds, not vegetable gardens, because of the urine.

Wood litter has no added scents, relying instead on the natural scents of the wood itself.

Some have other natural ingredients added such as green tea for extra odor control.

A few brands are Catit®, Catalyst™, Cedarific®, EcoPet, NextGen™, Weruva, and okocat®.

Sources used on this website are either primary or secondary.

Primary sources are always preferable and have the most reliable information because they’re original and directly referenced.

Scientific abstracts and data are good examples of primary sources.

Secondary sources are weaker because they usually consist of opinions or articles that give no sources of their own.

However, sometimes they refer to primary sources.

When I use secondary sources, most are those with some authority, such as veterinarian or cat behaviorist books and articles.
