The 8 Best Litters for Cats and Owners with Asthma
1. Dr. Elsey’s Precious Cat Respiratory Relief Litter – Best Overall
| Material | Clay |
| Weight | 20lb, 40lb |
| Clumping Capability | Yes |
Dr. Elsey’s Precious Cat Respiratory Relief Clumping Clay Litter is our best overall choice, as it is made specifically to help control respiratory disease in cats. While clay litters are typically the culprits for high dust production, Dr. Elsey’s formulated this litter to be hypoallergenic and low in dust.
This litter contains no perfumes, deodorants, or plant proteins. Clay litter can offer better odor control and clumping ability than some of the other types of litter and this brand does just that. Some users have reported that the odor control could be better, and they must clean frequently to avoid the ammonia smell in the urine.
Since this is a clay litter, it does still produce some dust, and this may be a no-go for some asthma or allergy sufferers. Overall, this litter does get great reviews, clumping ability, and compatibility with some mechanical and sifting litter boxes.
- Easy to scoop
- Works with sifting or mechanical litter boxes
- No perfumes or deodorants
- Minimal dust
- Still produces some dust
- Issues controlling ammonia smell
2. sWheat Scoop Natural Unscented Wheat Cat Litter – Best Value
| Material | Wheat |
| Weight | 12lb, 14lb, 28lb |
| Clumping Capability | Yes |
sWheat Scoop Natural Unscented Clumping Wheat Cat Litter is composed of wheat and contains no harmful ingredients, dyes, or perfumes. This is another flushable litter option that is biodegradable and environmentally friendly. The manufacturers claim it is 99.5% dust-free.
The wheat starch does form firm clumps to make litter scooping an easier task. There are wheat enzymes that are said to help neutralize litter box odors, but a lot of reviewers complain about the odor control of this litter. Overall, this litter is well-reviewed by cat owners and is a great, natural choice for any asthma sufferers.
This is another litter that seems to be easily tracked outside the litter box, which is inconvenient considering the cleaning that must take place when it is tracked throughout the house. Some cats could have wheat allergies, meaning they should stay clear of this litter. If in doubt, have a discussion with your vet about whether this could be appropriate for your cat.
- No dyes, perfumes, or harmful ingredients
- Flushable
- Biodegradable and environmentally friendly
- Not suitable for cats with wheat allergies

3. CatSpot Coconut Cat Litter – Premium Choice

Some reviewers complain that this litter is much too heavy and while it may be lower on dust than some other clay litters, it still produces too much dust for their satisfaction.

Buyer’s Guide: Selecting the Best Litter for Cats & Owners with Asthma
Before You Buy
Whether it is your cat that has asthma, or you or another member of the household with the condition, you will need to consider certain things before making your purchase.
Material
Knowing the material the cat litter is composed of is important. Those that suffer from asthma or severe allergies, whether human or feline, are going to want to look for litter made with fewer harsh chemicals, extremely low dust levels, and no harsh perfumes. Excess dust can be especially irritating for those with asthma.
Clay litter is great for odor control and clumping but is one of the worst culprits in producing dust. There are some designed to avoid dust, as you have seen on this list. The common theme for a lot of asthma and allergy-friendly litters are those made from all-natural ingredients such as paper, wheat, corn, and wood.
Keep in mind that while low-dust clay litters can work great for this purpose, you may notice that they may not clump as well and may have a short efficacy compared to those types with higher amounts of dust. You should also consider that allergy sufferers can have different triggers, so it may take some trial and error to find a material your cat doesn’t react to as strongly.
Cost
Any purchase will have you weighing the cost of the product. Of course, only you will be able to decide what kind of budget you are putting toward your cat litter. Make sure to look at the amount of litter you are getting for the price and the estimated length of use. It’s important to get good value for your money.
Your Cat’s Preference
Cats can be finicky and choosing a litter they will willingly use is essential. While some cats may use anything you put in their litter box, others may be hesitant to try new material or may not take well to a new texture. This could result in accidents outside the litter box in some cases.
If you start to notice your cat is refusing to use the litter box, ensure there are no other underlying health conditions or stressors that could be the root cause, and then consider the type of litter you are using. This could be trial and error so remember to have patience with your cat if you end up experiencing this.
Clumping Ability
Clumping litter can be very convenient when it comes time to clean the litter box. It binds any moisture together for ease of scooping and clean-up. Most top-of-the-line clumping cat litters are composed of clay, which as we know, is usually a producer of a lot of dust. If you want the convenience and odor control of clay litter and are an allergy sufferer, make sure you are opting for a brand that is devoted to dust control.
Most natural cat litters cannot clump, and this does make cleanup a bit more of a challenge. The sWheat Natural Scoop is composed of wheat and does have clumping capability. Many cat owners find great success with natural, non-clumping litters though, and it comes down to personal preference.
Cleanliness Is Key
Remember that no litter can completely trump the need for frequent cleaning. Keeping your cat’s litter box cleaned regularly will be beneficial for both you and your cat. This does not just go for asthma, but overall health and well-being.
