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.

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.

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.

4. Arm & Hammer Platinum Scented Clumping Clay Cat Litter

Another dust-free option, Arm & Hammer Platinum Scented Clumping Clay is a high-quality litter that no cat owner dealing with asthma symptoms should ignore. It is completely allergen-free and guarantees a full 7 days of odor control between full litter box changes. This cat litter formula is derived from plant fibers, which offer optimum urine absorption and clump creating.

Once the clumps are created, you can easily scoop them out to create a clean little box without having to completely change it. This cat litter for cats with asthma has micro-particles to ensure that your kitty’s paws stay safe and unscathed while using their bathroom area. This clumping litter even helps trap dander as your cat moves inside of it, which will help keep your home cleaner and your chores list shorter.

5. SmartCat All-Natural Clumping Litter

This stuff looks just like traditional cat litter, but it is almost completely dust-free. This SmartCat litter starts clumping up immediately after being exposed to feces and urine. It continues to solidify as time goes on, making it easy to clean up at the end of a long day.

With no added perfumes or artificial scents added, it is hard to believe that the litter box can't be smelled throughout the house. But the truth is that you won't notice any odors around the house when using this cat litter for asthmatic cats — even if you aren't the perfect litter box cleaner-upper. It's made from grass, so you can have peace of mind knowing that it won't harm your environment or impact your cat's asthma issues.

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.

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 of which product to choose, contact a vet - they might be able to give you a professional advice and make your job easier.
