Owning a cat is rewarding but requires cleaning up after them. While no one loves to clean the litter box, we love our whiskered, four-legged friends. An essential part of keeping a litter box in your home is choosing the right litter, which can make a difference in how your cat uses the box.
We want our cats to feel comfortable and have a relaxing place to use the bathroom. But with so many types of cat litter, it can be frustrating to find one that works for you. After all, if your cat rejects the litter box, you may have a bigger mess to clean up.
Two of the best types of cat litter are wood pellets and clumping cat litter. Both have advantages and disadvantages. If you’re trying to decide between the two, we’ll compare them in this article so that you can choose one that works for your cat.
Overview of Wood Pellets

Wood pellet cat litter is made from wood pellets, most commonly pine. Other types of wood can be used, but pine wood has a natural scent that masks odors without chemical additives.
Wood pellets have become more common since more pet owners prefer eco-friendly products. They are biodegradable and often made from recycled materials. They also last a lot longer than traditional clay litter, so you don’t have to change them as often.
How It Works
Wood is a highly absorbent material, which is why wood pellets are an effective cat litter. Like other types of cat litter, wood pellets work by absorbing the liquid from urine. When the urine is absorbed, the odor is neutralized.
When urine is absorbed, the pellets turn to sawdust. The sawdust settles to the bottom of the litter pan and leaves fresh pellets behind. The natural pine fragrance of the litter helps mask the odor.
No matter what kind of litter you use, bad smells often linger. That's where an effective litter additive like Hepper's Advanced Bio-Enzyme Cat Litter Deodorizer can make a big difference.

How to Clean & Change It
Wood pellet litter should be scooped once daily and completely changed once every 2 weeks. Daily cleaning is a two-step process. First, you’ll use a traditional cat scoop to remove the solids. Next, scoop out piles of sawdust and sift the scooper so that the dry pellets aren’t disposed of. Lastly, put the dry pellets back into the box and top with a fresh layer of pellets.
Although replacing the litter with fresh pellets every 2 weeks is recommended, you might get away with doing it less often if you scoop it every day. If you have more than one cat, you may have to change the litter more frequently.
To make litter-changing easier, you can also purchase a litter box with a built-in sifter tray. That way, the sawdust will filter through the sifter. All you have to do is remove the solids and empty the bottom tray of sawdust.
How to Dispose of It
Wood pellets are made from natural materials, so they are biodegradable and can be composted. However, you should be careful when composting since cat feces contain parasites that can cause toxoplasmosis in humans.
Keep a separate compost pile for wood pellet litter, and don’t use that pile on vegetables and other edible plants. If you don’t compost, you can flush the litter in small amounts or throw it away.

Overview of Clumping Cat Litter

Clumping cat litter is a variation of the original type of clay litter. It is made from small particles of different types of clay that stick together when exposed to moisture. The clumping action allows cat owners to remove some of the used litter without having to empty out the whole litter box.
However, clumping litter isn’t naturally scented. You can purchase it in unscented varieties, but it can cause your home to be filled with unpleasant odors. Scented versions are available, but they are fragranced with artificial chemical scents. Clumping litter isn’t usually rejected by most cats because it feels like a more natural place to relieve themselves.
How It Works
Clumping cat litter is primarily made from tiny particles of bentonite clay. When exposed to liquids, the bentonite clay particles absorb the moisture and stick together, hence the name “clumping” cat litter. Many owners prefer it because it is so easy and convenient to clean.
When the litter box is cleaned, you can simply scoop out the clumps, while loose litter will sift through the scoop and back into the litter box. You don’t have to have a special type of litter box or scoop. It produces dust, but with regular cleaning, clumping litter can last a long time.
How to Change It
The process for changing clumping litter is not that different from changing wood pellet litter. The most significant difference is that it’s much faster to sift and remove clumping litter when scooping because not all clumps settle to the bottom. If you have multiple cats, clumping litter should be scooped more often. If you only have one cat, you could probably get away with doing it every other day.
When you remove a clump, shake the scoop over the box to remove any loose litter. Dump the clumps of litter into a bag and continue until only loose litter remains. Every 2 weeks, the litter box should be completely emptied, cleaned, and replaced with clean litter.
To change the litter, dump the contents of the box into a bag. Since clumping litter sticks together, it can leave behind a mess in the bottom of the box. Therefore, you must clean the litter box with soap and water when the waste builds up. Then, rinse it off, dry it, and add fresh, clean litter.
How to Dispose of It
Clumping litter can harm the environment due to some of the chemicals it contains. It should not be composted or flushed. Instead, the bag in which you dumped the used litter should be tossed into your trash can with the rest of your trash.
- Cheap
- Easy to scoop

Other Things to Consider

Price
The price is a key factor when purchasing any product, and cat litter is no exception. Wood pellets tend to be cheaper, but you also have to consider the convenience of clumping litter.
Higher-quality cat litter will also cost more, regardless of whether it is wood pellets or clumping. High-quality cat litter effectively absorbs liquids and odors and lasts a long time. When choosing, you’ll have to consider whether or not you want to spend the extra cost to get a high-quality litter, and you may have to try out several brands before finding one that works for you and your cat.
Safety
Another factor to consider when choosing a cat litter is safety. Although clumping litter is convenient, there are some safety concerns that come with it. For starters, the bentonite clay in clumping litter may cause problems for your cat if they ingest it. It can interfere with digestion by causing blockages in their stomach and intestine as it absorbs some of the liquids found inside their body. This may not be a cause for concern if you haven’t noticed your cat eating litter. But if you have, clumping litter may not be the best option for your cat.
Another concern is the hazards to humans. Your cat can’t clean their own litter box, which leaves that job to you. Due to the toxoplasmosis found in used cat litter, it can be dangerous for pregnant women to scoop litter of any kind. But even if you aren’t pregnant, the dust caused by clumping cat litter can cause respiratory irritation, especially in litters that are scented with artificial fragrances. Wood pellets may be the better option if you have any respiratory illnesses.

What to Look for When Switching Litter
If you’ve used a different type of litter before and are making a switch, you need to look for certain features to ensure that the new litter is safe and effective for your cat. For starters, cats can suffer from allergies and skin sensitivities just like humans.
With either type of litter, you’ll want to look for signs of an allergic reaction, including respiratory problems or skin irritation. This is especially true for fragranced litter, but even wood pellets can be problematic for some cats. Discontinue using the litter if it is causing problems for your cat.
You may also want to monitor your cat’s litter box habits for a few days after switching litter. With wood pellets especially, some cats may not like the texture of it if it isn’t what they’re used to. They may start relieving themselves in other places, leaving you with more unpleasant messes to clean up. Some cats take longer than others to warm up to the idea of new litter, while others may not warm up to it at all.

Conclusion
When choosing cat litter, it is important to make an informed decision to ensure it works for you and your cat. Wood pellets are more environmentally friendly, but clumping litter tends to do a better job of controlling odors and is more convenient to clean. However, it also produces dust and is more expensive. The decision ultimately comes down to what you’re comfortable with paying for and cleaning and, most importantly, what your cat will actually use.
