Cat standing in the kitchen — advantages and disadvantages of tofu cat litter
Short answer

Tofu cat litterIt is produced by turning the soybean pulp (okara) left over from tofu production into pellets. It clumps, produces low dust, is lightweight and biodegradable. Weaknesses: Deteriorates quickly in a humid environment, its price is relatively high, and its thin cylindrical pellet form is a texture that some cats need to get used to. Among the herbal sands, it is one of the ones with good odor control.

Tofu cat litter is an option that has spread from the Asian market in recent years. In this article, we discuss how it works, its strengths and weaknesses, and its differences from other herbal sands.

What is Tofu cat litter?

In tofu production, soybeans are crushed and filtered; remaining fibrous pulp okara It is called. This pulp is dried and pressed into thin cylindrical pellets. So the raw material is a by-product of the food industry — it carries a similar circular logic to olive stone sand.

Pellets are generally 2-3 mm in diameter and short in length; It is larger than bentonite granules and thinner than pine pellet.

How does it work?

Soybean fibers absorb liquid quickly and the wetted pellets stick together and form lumps. Clumping performance is considered good among vegetable sands — with olive stone sand It is at a similar level, not as hard as bentonite.

Odor absorbers such as green tea, corn or activated charcoal are added to some tofu litter products. How activated carbon works in this article we told.

Humidity and storage

This is the most critical weakness of tofu sand. Soybean pulp loses both its structural integrity and clumping power when it absorbs moisture. If an opened package sits in a humid environment for several weeks, its performance drops noticeably.

Storage rules: Store the package tightly closed in a dry and cool place. Stay away from bathrooms, balconies and basements. If you notice clumps, discoloration, or a musty odor in the sand, replace it all. Detail: How to store cat litter, risk of mold.
