Material and Durability

Both the fence and ramp are made from high-quality plastic that resists wear. The ramp features non-slip rubber feet that keep it stable on any floor. These materials do not absorb odors and are easy to wipe clean. They are built to last through years of use without cracking.

Ease of Cleaning

The fence can be removed in seconds and rinsed under water. No tools are required. The ramp can also be disassembled for thorough cleaning. Smooth surfaces mean litter does not get trapped.

Effectiveness at Reducing Tracking

The fence catches litter as your cat exits, preventing it from scattering. The ramp encourages a slower exit, which further reduces tracking. In multi-cat homes, using both the fence and ramp provides the best results. Many owners report significantly less litter on the floor after adding the ramp.
