Things to consider about litter for Asthmatic Cats


The composition of the litter must not have the allergens that cause your kitten to cough and wheeze. It’s the basic requirement for these cat litter. Make sure the are no artificial fragrances or perfumes added, which will worsen the asthma in cat. 

Odor control

It’s an important feature that you should definitely need to prevent the intense scent from affecting the cat’s breathing.

ECO friendly

Basically, dumping litter in the trash can or flushing it using your toilet is not very environmentally friendly. If you care about this matter, which I think we all should, then you should buy a litter with self-degradable features. For example, cat litter made from recycled paper has become very popular in recent years. 


The price may vary depending on many different factors. But you only should buy a product at a reasonable price. Otherwise, it would be better to use sand and small gravel for the job. They are not allergens, just a litter more difficult to clean up. Or if you can, training your cat to poop on the toilet is not a bad idea.

Dust Free Cat Litter for Cats With Asthma

Most of the litter that's sold online produces dust when you pour it into your cat's litter box. This can cause you and your cat to cough and choke, and can lead to health problems for your cat and yourself.

Dusty litter can cause irritation, such as wheezing and coughing, and may even trigger an asthma attack.

Clumping clay cat litter is typically the litter which produces the most dust, when compared to the other types of cat litters. It contains crystalline silica, which can cause respiratory problems.

Keep in mind, that the dust that's found in clumping sodium bentonite clay litter, can get stuck on your cat's fur and paws. This is especially dangerous because when your cat grooms his or herself, they will consume some of this dust.

Once it's inside your cat's intestine, sodium bentonite clay can expand up to 18 times its original volume when it comes in contact with moisture. This is very unhealthy and dangerous for the digestive tracks of cats and kittens.

In addition to this, keep in mind that cats will usually leave a trail of dust inside your home, from their dusty paws. So the dust will spread to other parts of your home. You will need to vacuum your floors regularly, in order to remove tiny dust particles.

How to keep the litter box clean for a long time?

The answer is simple, frequently scooping, choose the right litter, and don’t pour too much litter each time. This may keep your little box stay clean for at least one month before you need to clean the whole box.

To keep the area around the box clean, try using a non-stick cat litter, you can find them here. Another helpful tip, is to switch over to a stainless steel litter box, instead of using a plastic one. 

This is much more hygienic, compared to the plastic litter boxes, because bacteria can not build onto the steel surface. Stainless steel litter boxes are also very durable, and will last years of use. 

How do I teach my new kitten to use the litter box?

If you have a mother cat, then it’d be very easy since it will guide the small kittens to use the box. Or the little one will copy its senior actions. But if you don’t, try to choose the right litter with an attractive smell.

Gently grab your kitten and drop it in the litter box. It’ll begin to feel excited about the litter and find out that this is a really great spot for pooping and urinating in later.

Best way to control litter box odors?

Choose a litter with strong odor controlling feature, keep your litter box in a dry and expose to sunlight spot. The sunlight is a great way to remove awful smell without applying any odor remover. But if the situation is not good, you’re free to use it.
