It's important to use dust-free litter and ensure proper ventilation when cleaning the litter box.

Is it harmful if my cat accidentally ingests cat litter?

While small amounts of ingested litter usually pass through without issue, larger amounts or repeated ingestion can cause digestive blockages or other issues. It’s advisable to use non-toxic, natural cat litters to reduce the risk of harm if your cat does ingest some.

Can cat litter cause skin irritation?
