The shelf life of cat litter varies depending on factors such as material and packaging, generally ranging from 1 to 3 years.
Common bentonite cat litter, if properly sealed and stored, typically has a shelf life of 1-2 years. Its main component is natural bentonite, which is relatively chemically stable, but it may clump over time due to moisture absorption, affecting its usability.
Tofu cat litter, made from plant fibers such as tofu residue, generally has a shelf life of 1-3 years. It is susceptible to environmental humidity; if not stored properly after opening, it is prone to mold and mildew, shortening its shelf life.
Crystal cat litter has a shelf life of approximately 2-3 years. It has strong absorbency and deodorizing properties, and good chemical stability. If properly sealed, it has a longer shelf life.
To ensure the performance of the cat litter and the health of your cat, it is recommended to use it within its shelf life and use it up as soon as possible after opening. Ensure it is sealed tightly and stored in a dry, cool place.
