A reconfigurable pet enrichment system designed to help pets fulfill their natural behaviors is provided. The system is arranged to facilitate an environment that helps stimulate, entertain, and exercise a pet, and also provides a defensible space for napping, resting, or sleeping. The system is constructed from two separate pieces of pliable material. A base component is fashioned with a non-slip element. A top-covering component is attached to the base component, by means of semi-permanent fasteners, to create a variety of forms such as ripples, nooks, and tunnels. The top component contains a plurality of differing sized openings. Openings appeal to a pet's predatory nature, as the openings provide a source of stimulation and interaction. The pet enrichment system may be formed of any desired material, so as to be safe for pet interaction. The system may also be configured with a plurality of members attached via semi-permanent fasteners.
