Top 5 Best Litters for Cats with Asthma
1. Dr. Elsey’s Respiratory Relief Cat Litter — Best Overall
This clumping clay cat litter is designed to provide relief to cats of all ages that are suffering from respiratory problems, including asthma. Dr. Elsey’s Respiratory Relief cat litter is hypoallergenic and free of perfumes, artificial deodorants, and proteins from plants. This litter is formulated to minimize dust by more than 99% and includes natural essences that help reduce overall stress.
This cat litter offers awesome odor control, so you won’t smell your kitty’s business throughout the day. It works with both regular and mechanical litter boxes. Therefore, there is no need to invest in a special one to use this litter. Simply fill your cat litter box about 4 inches full of this litter, then scoop the clumps away once or twice a day to keep the box clean and your cat free of asthma symptoms. It’s a little more expensive than many other options on the market, but the cost is well worth the health of a kitty family member.
To conclude, we think this is the overall best litter for cats with asthma.
- Clumps quickly
- Over 99% dust-free
- Easy to use and manage
- More expensive than other options on the market
2. sWheat Scoop Multi-Cat Unscented Clumping Cat Litter – Best Value
Made especially for multi-cat homes, this unscented litter is perfect for small apartments and large houses alike. It offers long-lasting odor control that not only hides the odor but also neutralizes it for true fresh air throughout your home. The starches in the wheat clump up quickly and noticeably, so you always know when it is time to change the litter box.
It is an eco-friendly formula product that is completely biodegradable and can be composted with your yard waste rather than put into the garbage bin. Furthermore, you will never find any hidden dyes or unnatural ingredients lurking within this cat litter formula that could cause your cat’s asthma symptoms to act up.
- Made specifically for multi-cat households
- Unscented to please sensitive noses
- Clumps tend to fall apart during cleaning
- Odors may develop while scooping
3. World’s Best Clumping Corn Cat Litter — Premium Choice
This is another excellent clumping cat litter that is laced with natural lavender oil to help relieve your cat’s stress and asthma symptoms. Your home will never smell of ammonia or urine, thanks to this low-dust formula. The clumping action works quickly, so you can easily scoop the dirty litter out and keep your cat box clean throughout the day.
This is an environmentally friendly product that will not make a negative impact on your household’s carbon footprint. In fact, it is flushable, which makes it easy to work with and will save you time in the long run. Also, no silica dust is present in this formula, which will help your cat breathe better as time goes on. However, the downside is that some cats and/or owners simply don’t enjoy the lavender scent of the litter.
- Fast clumping action

- Environmentally friendly
- The lavender scent may not be pleasurable to all cats and owners
4. Arm & Hammer Platinum Scented Clumping Clay Cat Litter

It is completely allergen-free and guarantees a full 7 days of odor control between full litter box changes.

Buyer’s Guide: Finding the Best Litter for Cats with Asthma
Now that you have a good idea of what kinds of cat litter are available for your asthma-prone cat, you must decide which one to invest in. Hopefully, the following buyer’s guide will help you decide which type of cat litter would be best for your household. Here is what you need to know.
Know Your Scooping Preferences
It’s a good idea to make sure that you know what your scooping preferences are before choosing a new kitty litter to invest in. Do you prefer the litter to clump up before scooping it clean, or would pellet-style litter that expands be more convenient for you? You are responsible for cleaning the litter box out, not your cat. So aside from odor control, your scooping preferences should be your biggest consideration when comparing litter options.
If you aren’t sure what your scooping preferences are, pick up a few inexpensive litters at the grocery store that have different scooping options. Choose one that clumps, one that expands, and one that hardens, then try each one at home to see what you and your cat like best. Then, you can choose a high-quality option that will help you effectively manage your cat’s asthma symptoms.
What’s Controlling the Odor?
Most cat litters feature some kind of odor control to help keep households smelling fresh even when the litter box isn’t completely clean. However, not all odor control ingredients are created equally. Some litters harbor artificial scents that could exasperate your cat’s asthma problems. Others include essential oils that don’t always agree with some cats, whether due to a dislike of the smell or an allergy reaction. Still, others rely on the litter itself to absorb odors and keep things smelling fresh at home — but they don’t always perform as well as litters that include some kind of scent.
Talk to your veterinarian to find out whether there are any allergy issues to be aware of when deciding what type of odor control your new cat litter should have. No matter which one you choose to invest in, make sure it doesn’t include any artificial scents or odor-blocking technology, as you never know how the artificial ingredients will affect your cat.
If you're dealing with stubborn smells in your litter box or elsewhere in your house, a good cat litter deodorizer can work wonders.

We recommend Hepper's Advanced Bio-Enzyme Cat Litter Deodorizer, an all-natural litter additive that fights odors using bio-enzymes. This effective deodorizer is fragrance-free and works on all types of cat litter. It's also effective anywhere you have lingering odors, including diaper pails, garbage cans, and kennels!

Pay Attention to the Packaging
It is also important to pay close attention to the packaging when choosing a new litter for your cat. If the packaging doesn’t stay sealed between uses, the litter inside can become damp or get dirty and thus, no longer usable. Your new cat litter should be in a package that is resealable or stiff enough to stay closed when you fold it.
If you are unsure of whether a product’s litter packaging will stay closed but you don’t want to choose another product, invest in a large bag clip so you can secure the packaging closed if necessary and ensure that the litter inside won’t succumb to the elements.
If you’re still unsure, your vet might have better advice as to which product yu should choose.
If you need to speak with a vet but can't get to one, head over to PangoVet. It's an online service where you can talk to a vet online and get the personalized advice you need for your pet — all at an affordable price!
