Usage Tips

Litter Depth

Tofu litter: 5-8cm, Bentonite: 5-6cm, Pine: 2-3cm. Too thin causes sticking, too thick wastes litter.

Change Frequency

Tofu: every 7-14 days, Bentonite: every 7-10 days, Crystal: every 15-30 days. Multi-cat homes should change more frequently.

Daily Cleaning

Scoop at least 1-2 times daily, add fresh litter after scooping. A clean litter box promotes cat health.

Beginner Tips

Start with tofu or mixed litter — low dust, easy to clean. If your cat rejects it, try bentonite (highest cat acceptance).
