Whether you should use cover or not depends on your cat’s habits. Covered boxes give more privacy and if the cat seems to prefer eliminating in seclusion, then using a covered litter tray is a good choice. Furthermore, it’s an ideal solution for cats that like to dig in their litter, but also for cat owners to keep their home and the area around the litter box smelling fresh. This Tray Cover fits perfectly on the our white Cat Litter Tray. Material: PP. Dimensions: 51 x 25 x 38 cm.
