For deodorizing, large-capacity cat litter, the flushable and easy-to-dispose paper type is convenient
Updated Oct 16, 2026・price checked Oct 16, 2026
When you buy cat litter in bulk, you may struggle with where to store it right after it arrives, and start noticing odor before you use it all up. While large-capacity packs are economical, if you don't also consider ease of disposal, storage and disposal can become more troublesome.
Yuuen's pick
If you don't want to struggle with disposal even with a large capacity, Iris Ohyama's 'Paper Cat Litter 7L×6 Bag Set' is an easy-to-handle choice.
* Re-picking uses one of your searches.
Before you buy
Check the weight per bag, the packaging size of the 6-bag set, and whether it's scented on the product page before buying.
How to choose
- Decide the amount needed based on the number of cats and replacement frequency
For one cat, a 7L pack is roughly 1-2 weeks' worth. For multiple cats, multiply by the number of cats and calculate monthly consumption in advance so you won't struggle with timing when restocking.
- Decide between paper or bentonite based on disposal method
Paper type is easy to dispose of since it can be flushed down the toilet or thrown out as burnable garbage. Bentonite clumps firmly, but you need to check your municipality's rules for sorting burnable and non-burnable waste.
- Compare deodorizing mechanisms
Deodorizing mechanisms such as decomposition-neutralization, antibacterial action, and scenting differ by product. Whether family members living together are sensitive to scent is also a selection criterion.
- Secure storage space beforehand
Large-capacity packs often arrive as boxes, such as a 6-bag set, so deciding on a storage spot before ordering will help you avoid scrambling after receiving it.
Who it's for / who it isn't for

Why this one
For ¥3,380 you get 7L × 6 bags, totaling 42L, which comes to about ¥80 per liter. Even households that buy cat litter monthly can reduce shopping trips by buying in bulk.
Since the main ingredient is recycled pulp, after use it can be flushed down the toilet or disposed of as burnable trash. This reduces confusion over burnable/non-burnable sorting, unlike mineral-based litters.
At about 2kg per bag, it's light enough to move stock easily even in apartments with stairs.
In addition to decomposing and neutralizing odor where urine lands, it has antibacterial effects, making it easier to control odor even on days when cleaning is delayed due to multiple pets.
Downsides
- Paper pellets don't clump as firmly as mineral-based litter, so they can crumble easily during cleaning
- Since it comes in a set of 6 bags, you need to secure storage space in advance
- This is not a scented type, so it may feel insufficient if you want strong fragrance-based odor control

FAQ
- How long does 7L × 6 bags last?
- For one cat, it lasts about 1-2 months. This can vary depending on the litter box size and how often you change it, so decide your next purchase timing based on actual usage.
- How long does the odor-control effect last?
- Removing clumped portions each time it's used helps maintain the odor-control effect. A full replacement is recommended every 2-4 weeks.
- Is this enough for multiple cats?
- With 2 or more cats, consumption increases, so even 7L × 6 bags may be used up in less than a month. You'll need to shorten the interval between purchases depending on the number of cats.
