Hypoallergenic Cat Litter Buyer’s Guide

Allergic reactions to cat litter happen when the immune system has an overreaction to everyday items. Your immune system tries to flush the allergens out of your system by making you sneeze, cough, itch, or have watery eyes. Both humans and cats can have allergic reactions to litter. And they can develop immediately or occur over time.

If you notice this with your cat, it may send you scrambling to find a hypoallergenic cat litter. After all, litter is necessary if you have a cat. They have to come into contact with it when they go to the bathroom. You have to touch it when you change their litter or touch something the cat tracked litter on. But what makes up a hypoallergenic cat litter?

Important Hypoallergenic Cat Litter Components

There are a handful of things you want to consider when you start comparing this type of cat litter. Using this short outline will help you narrow down your choices much faster.

100% Free of Dust

To be hypoallergenic, your cat litter has to be at least 99% dust-free. When you pour litter or your cat kicks it up, the dust releases into the air. This is what can easily trigger allergies.


You’ll have to decide on a litter material to use. If you make this one of your first priorities, it’ll narrow your choices down out of the gate. This usually comes down to your cat’s preferences. Clay is very popular, but it shouldn’t contain sodium bentonite. This is the material that produces dust in cat litter, and it’s a popular sealing agent.

Size of the Pellets

Cat litter comes made out of pellets or grains. The smaller grains are popular for cat parents that use mechanical litter boxes because it has fewer chances of clogging up the machine. Generally, pellet litter is better for cats with long hair because there are fewer chances that it’ll stick to them.

Scent or Scented

Many cat litter brands use scents in their formulas that give the litter a better chance at covering up any odors. However, perfumes and artificial scents are a big allergy trigger. Ideally, your hypoallergenic cat litter won’t have a scent. Most don’t as a general rule.

Disposal Method

Some of these litters require you to scoop them into a bag and throw them away. Other cat litters are safe to flush down your toilet without clogging your septic system. If this is important to you, double-check the label. It’ll tell you whether you can flush the litter. You can also consider getting one of the disposal systems.

Odor Control Guarantee

No one likes the smell of a cat box, so odor control is important. Many cat litter brands have an odor control guarantee that claims to trap odors and eliminate them for a week or two. Check the guarantee and follow the guidelines to keep your home smelling fresh.
