how often to change cat litter crystals

It’s recommended to change crystal cat litter every 2-3 weeks for a single cat, or when the crystals become saturated.

Crystal cat litter is designed to absorb moisture and control odor more effectively than traditional clay-based litters. Typically, it lasts 2–3 weeks for a single cat, but usage can vary based on the cat’s hydration level, urination frequency, and environmental humidity. Signs like strong odors, yellowing crystals, or moisture pooling indicate the need for earlier replacement. Regular scooping of solid waste can help extend the litter’s lifespan. For households with multiple cats, more frequent changes are usually necessary to maintain hygiene.
