What to Look For?

When considering opting for a litter for cats with allergies there are a few factors to be aware of which we will go into detail later on.

First, it's a good idea to get a sense of what it is your cat is allergic to or reacting to so that you can best tailor your purchase. Your vet may be able to help diagnose this, or reading the ingredients of your cats’ current litter may help you get a better sense of the situation. 

Often cats react to the dust or fragrance used in the litter, looking at addressing these is a good place to start. 


Just like humans, cats can be irritated by dust too. 

Opting for dust-free litter is a good place to start to address your cats’ allergies. Be mindful that although some litters label themselves as 99% dust-free, they may still contain dust. 

In that case, natural litters such as ones derived from coconut or walnut may be better, although these sometimes have tracking issues. 

Clay litters are often the most common for causing dust so they are generally a good one to avoid. 


The fragrance is used in cat litter to conceal any smells from the waste. It also can be an irritant to your cats as it is made of chemicals.

While it will help with the smell of your home, a lot of fragrances use chemicals that can cause allergies and respiratory issues for your cat. The issues include fur loss, itching, and inflammation. Unscented litters are a good option if you think your cat is suffering because of fragrance. 

There is no clinical proof, but clumping litter can reduce allergies. This is because clumping litter absorbs moisture, dust, and chemicals in the air. Clumping litter is often easier for you to clean the litter box as well.

Opting for a fragrance-free or unscented litter is a good option to reduce the chance of allergic reactions from your cats, with lots of unscented litters offering great odor control.  

How Much?

Cat litter, especially for those with allergies, can range widely in price. Make sure to set a clear budget before you begin your search. 

There is a litter to fit every budget that won’t upset your cats.

Pellet Size?

When buying your litter, the choice of pellet size is bound to come up. 

Pellet litter is a better choice for cats with long hair.  It also helps to reduce tracking and leaves your house cleaner. Cat litter made up of smaller grains, a common one for hypoallergenic litters, are a good choice for mechanical litter boxes, but may cause tracking issues. 

Think about what works best for your house, and of course your kitty!

Frequently Asked Questions

Can cats be allergic to litter?

Just like people, cats can have allergies too. They can be allergic to the dust, fragrance, or chemicals often used in litters. 

This can be very uncomfortable for cats, which is where changing your litter can be useful to help your cat. 

Hypoallergenic litters are typically low in dust, made with natural ingredients or free of chemicals, removing a lot of the common allergy triggers. Remember to speak to your vet if you are concerned about your cat’s allergies.

What are the signs of a cat allergy to litter?

There is a range of symptoms that can show your cat may be allergic to your litter. 

Some symptoms to look out for are: 

  • Sneezing or coughing
  • Cat not feeling comfortable in the litter
  • Swollen face due to scratching 
  • Itchy skin
  • Severe cases: snoring, vomit, diarrhea, and coughing
  • Acne, cysts, and pimples on the face which may remain without discharge

Be sure to check with your vet if you are concerned about any of these symptoms and check your current litter for anything that could be irritating your cat. 

Can you flush litter?

Some litter can now be flushed in small quantities, especially those made from natural ingredients or are biodegradable.

Be sure to check on the litter (and our reviews which ones are flushable!) before you flush and remember to only flush in small quantities. 

How often should I replace cat litter?

Cat litter usually has an odor control guarantee for a certain amount of days, for example, 7. After those 7 days smells such as urine can arise, an indicator of time to change the litter. 

Some people change it more frequently, depending on how much mess is in the litter tray. If you have multiple cats using the litter, then you will need to change it more frequently. 

Those opting for an unscented litter for their sensitive cats may want to change their litter more frequently to avoid any smells. 

Remember that fresh air can help with the smell, read the recommendations on the box and be in mind that the more you change the litter the quicker it will run out. 

Perhaps opting for a cheaper version of it will be changed often! 


Toxoplasmosis is an infection caught from the feces of infected cats. Generally, it's harmless for humans but can cause serious problems for some people. 

Usually, it presents itself as flu-like symptoms that can improve on their own in six weeks and once you have had it you cannot catch it again. 

Speak to your doctor if you are concerned, or if you are in a higher-risk category such as being pregnant or have a weakened immune system. 

In cats, toxoplasmosis is caused by a single-celled parasite Toxoplasma gondii. It is more likely to develop in cats with suppressed immune systems, young kittens, cats with feline leukemia, and feline immunodeficiency virus. 

Common symptoms include fever, loss of appetite, and lethargy. Other symptoms such as breathing difficulty, liver damage, bladder control, and the eyes and central nervous system. 

If you are concerned about your cat please seek medical aid as soon as possible. 

Good preventative measures include routinely cleaning feces out of the litter box and exercising good personal hygiene at all times.
