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.
