Tunnels provide an environment where cats can hide, which taps into their natural hunting behaviors. They can use the tunnel as a hiding spot to stalk and pounce on imaginary prey or other pets.

Cats enjoy the element of surprise, and tunnels offer an excellent way to engage in ambush play. They can hide inside and leap out at passing objects, people, or other pets.

Tunnels offer a confined, enclosed space that can make cats feel secure. This sense of safety is important for their well-being, as it provides a retreat where they can relax without feeling exposed or vulnerable.
