Pet Screen

Disclosed is a pet screen, including a main plate assembly and two connecting members for fixedly connecting headrests of car seats. The main plate assembly includes a main block and two side blocks, where the two side blocks are hinged with left and right sides of the main block, and the two side blocks are arranged to be foldable or expandable relative to the main block. The two connecting members are arranged on the two side blocks respectively. The main plate assembly can be secured on the headrests of car seats through the connecting members, which separates the trunk space from the rear space, and efficiently delimits a pet activity area, thereby ensuring driving safety due to no pet disturbance to the driver, and enhancing the utilization of interior space.
