Best Cat Litter for Odor Control

Cats are notoriously low-maintenance pets as well as being the fluffy and adorable companions we all love.

They’re known for being fiercely independent, regardless of whether they’re indoor or outdoor cats. Whereas dogs require trips outside and a walk when they need to use the bathroom, cats prefer using a litter box.

Anyone who’s owned a cat will know the familiar ammonia odor that comes along with the job and the consistent scooping. How stinky the litter box smelled will depend on how often you scooped and most importantly, the type of litter you use.

If you want to keep your home smelling fresh, it’s important to invest in a high-quality litter that’s absorbent and reduces odor. It can be difficult to know what litter to purchase as there are several factors that you should take into account such as material, whether it clumps and its absorbency.

All of these factors can influence how bad your litter box can stink.

In this article, we’ve compiled a list of some of the best cat litters for odor control on the market at the moment and highlighted their key features.

Best Cat Litter for Odor Control Buying Guide

Before deciding which cat litter you’re going to buy, you need to consider a few things first such as which type is most suitable for yours and your cat’s needs, what features it comes with, how much it costs, and how easy it is to clean.

With so many options on the market right now, it can be overwhelming and time-consuming to try to figure out which is the perfect litter.

So to prevent you from making any cat-astrophic errors, below is our helpful Buyer’s Guide which provides a rundown of important factors to take into account before making a purchase.  

Clumping or Non-Clumping?

Clumping cat litter forms into solid, compact lumps when wet. This makes it easy to only scoop out the waste while leaving the clean litter in the tray, increasing the life span of each litter re-fill.

However, clumping cat litters are typically less bio-degradable. Litters that disintegrate or turn to sawdust when wet will breakdown and decompose quicker making non-clumping the most suitable type if you wish to compost your used cat litter.

Cheap non-clumping litter can leave the litter tray smelling nasty due to it soaking into the entire tray contents. If convenient cleaning is important to you and you’re comfortable with everyday scooping, then clumping cat litter could be a great option for you.

Material, Type, and Texture

Different cats will prefer different textures, you will want to avoid ones that are too fine or gritty as they could get caught in between your cat’s toes and claws which can be messy and painful.

The texture will depend largely on what the litter is made from. Below are the most common types:

Clumping Clay Litter

Clumping clay litter is the most popular type of litter as it’s widely manufactured and can be relatively cheap compared to other options. It’s usually satisfactory at controlling odors and makes cleaning out the litter box a breeze.

Some clumping clay litters are made with natural deodorizers such as activated carbon or baking soda, which can help to neutralize odors.

However, clumping clay litters are not suitable for kittens. This is due to the fact that sodium bentonite clay can lead to intestinal blockage in small kittens and they shouldn’t come into contact with it until they’re at least 3-4 months old.

It’s important to check the ingredients and guidelines on your specific cat litter to find out if it’s suitable for you and your cat.

Non-Clumping Clay Litter

Unfortunately, non-clumping clay cat litter is notorious for its lack of odor control.

Unlike clumping clay, which is made from sodium bentonite clay, this type of litter is made with clay that absorbs but doesn’t clump.

This means that you can’t scoop out urine. Ammonia odors will build up quickly. You’ll need to dump out all the contents of the litter box every few days, possibly costing you more money.

Silica Gel Crystal Cat Litter

This next cat litter is made from highly absorbent silica gel crystals. These crystals are very good at soaking up urine and are non-toxic to your kitty. Instead of clumping, this type of litter simply absorbs urine and dehydrates feces.

This makes it super easy to clean and therefore less likely to get stinky. If scooping up litter grosses you out, you’ll love silica gel crystal cat litter.

Simply scoop out any solid waste, stir the remaining litter, and throw it in the garbage and replace it when it begins to develop a yellow-brown tinge. It’s even proposed that you can get away with fully cleaning out and replacing silica gel litter as infrequently as once a month. 

Natural Cat Litter

There are a variety of natural alternatives to clay or crystal cat litter. These are typically plant-based and free from any harmful additives.

One of their main selling points is their biodegradability, which sets them apart from clay litters, which don’t break down in the environment. Popular types of biodegradable litter include corn, wheat, walnut, wood, grass, and paper.

Below are a few of our favorite types of natural cat litters and why we love them:

  • Wood litter- Wood pellet cat litter is super absorbent and great at keeping bad odors at bay as they often fill your home with a pleasant pine scent. While effectiveness can vary from brand to brand, the natural capillary system of wood fibers traps moisture and odors for long periods of time. Both clumping wood litter and non-clumping pellets are available. Of course, the clumping type works best, but non-clumping wood litter also has a good reputation for odor control. So if the odor is something you want to avoid, you’ll find yourself pine-ing for the wood pellet kind. 
  • Grass litter- Cat litter made from grass is one of the most effective biodegradable cat litter types on the market. It also has very good odor controllability and clumps well, making it easy to clean up.
  • Corn cat litter- Cat litter made from corn isn’t as common as wood and grass, but it’s a popular choice among those who want a planet-friendly alternative. It’s highly-absorbent, it clumps well and it’s great for odor control. However, corn cat litter is prone to aflatoxin mold growth, which can lead to disease and other health complications. 

Frequently Asked Questions

What other factors should I take into account when trying to reduce litter tray odor? 

Apart from changing what type of cat litter you use, there are a few other factors that could influence the level of odor control you can achieve. The first is the number of litter boxes you have in your home.

The general rule is that you should have one litter box for each cat that you have, plus an extra one. So, if you have four cats, you should have five boxes. Having a sufficient amount of litter trays helps to prevent high-stress levels in your cats and keeps litter-tray avoidance at bay, so there’s less clean-up in the long run.

Location, location, location. The placement as well as the amount of litter boxes in your home is crucial to the reduction of bad odors. Keep the trays away from heat sources and warm spots in your home as the waste will slowly cook and potentially emit a stronger odor.

It’s best to keep litter trays in a cool, dry place as well as a calm place with minimal traffic where your cat will feel relaxed. Providing a safe, low-stress space for your cat to use the box can also prevent inappropriate urination which will help to keep your home smelling fresh. 

Litter deodorizers are good last-resort if you’ve already assessed your litter-box location and quantity. They come in a variety of types, such as basic powders which are typically made from baking-soda, heavier alternatives are made from zeolite, and other odor-neutralizing products like deodorizing sprays and deodorant beads.

These tend to have a pleasant scent, however, cats tend to dislike perfumes and strong chemicals so an air purifier may also be a good option if this is the case for you. To save some cash, we recommend sprinkling a little bit of ordinary baking soda into the tray in question. Baking soda is highly effective at reducing odors and made without artificial fragrances that could irritate your cat.
