The invention belongs to the field of consignment boxes and particularly relates to a pet consignment box. The pet consignment box comprises an outer cage mechanism and an inner cage mechanism, wherein the inner cage mechanism can freely rotate in the outer cage mechanism. The pet consignment box has the advantages that the whole pet consignment box is a combined universal structure, a pet in a ball cage can constantly stand without rolling when the optional one face of the box contacts with the ground, and pet injury caused by collision caused by violent operation is avoided; excrement in a spherical-surface circular shell can constantly stay at the center of the internal concave face of the spherical-surface circular shell and cannot spill due to consignment box rolling and collision tocause pollution.
