Cat litter box liners are disposable bags designed to fit inside your cat’s litter tray, making litter changes cleaner and much easier. They act as a protective layer between the litter and the box, helping prevent stuck‑on waste, staining, and odors. When it’s time to clean, you simply lift the liner by its edges, tie it up, and throw it away—saving time and reducing mess. Many liners are made from durable, leak‑resistant materials and come in various sizes to fit different litter box styles. Using liners can help keep your cat’s space fresher and make maintenance more convenient for you.
