Abstract: An assembled pet framework made of paper includes a geometric body made of corrugated paper and cut to not only form therein a geometric through hole but also obtain a geometric cylinder, a geometric disk, geometric rings, a disk and a plate centrally provided with a geometric hole, which are put together to form a pet toy framework. Multiple geometric bodies and multiple geometric rings are put together to form a pet toy maze. The corrugated paper is made from eco-friendly, recyclable and reusable materials. Body-shaped corrugated paper and plate-shaped corrugated paper are cut with a minimal waste of materials or even without wasting any materials to therefore protect the environment and save materials. The bodies, rings, and disks are coupled together to form pet-related devices of different shapes. Multiple bodies and rings together form a cat maze in which cats play.

Abstract: A package box for containing an object and being turned inside out to form a pet kit includes: a bottom panel; four lateral panels integrally formed with the bottom panel; a top panel coupled to the lateral panels by joint structures, wherein the bottom panel and the lateral panels together define a receiving space for receiving the object, and the top panel caps the receiving space; and a cat scratching pad fixedly disposed on the back of one lateral panel and penetrated by a geometric hole. A geometric perforation corresponding in shape to the geometric hole is formed on two opposite lateral panels. Users unfold the package box and then fold it inside out to form a pet kit, expose the cat scratching pad, and remove a plate from within the geometric perforation, such that the pet kit is equipped with a cat maze playground and the cat scratching pad.
