Feline digging behavior on soft surfaces, such as bedding, is a common activity exhibited by domestic cats. This instinctive behavior manifests as repetitive scratching and pawing motions directed at the material.
This behavior stems from several innate drives. One is scent marking, where cats deposit pheromones from their paws onto the surface, claiming it as their territory and providing a sense of security. Another is related to the evolutionary instinct to prepare a comfortable and safe sleeping area, mimicking the digging and nest-building behavior of wild ancestors seeking shelter or concealing prey. Furthermore, the texture of the bedding might simply be stimulating and pleasurable for the cat.
