A pet bed combination apparatus is constructed of three cushions, with two edges of each cushion attached to a different one of the other cushions. The pet bed combination has a front and rear opening and forms a tunnel structure that a burrowing pet can enter to and exit from either of the two openings. The pet bed combination is triangular in shape when viewed from the front or rear opening. The pet bed combination can be used by a pet for exercise or as a place to rest, and the dimensions of the pet bed combination are selected so that when the primary pet using the apparatus tunnels into the bed, the three inside surfaces of the apparatus are in contact with the pet.
