PROBLEM TO BE SOLVED: To provide an assembling type pet house which is more ventilated and hygienic than conventional ones, and at the same time has high mechanical strength. SOLUTION: A main body part 2 has a back plate member 10 having a predetermined outer shape that covers a back surface of a housing space 3, and a back plate member having the same outer shape at least from a lower end thereof to a predetermined height position. A plurality of frame plate members 11 and a connecting mechanism that detachably connects the frame plate members 11 in a state where they are arranged in parallel at predetermined intervals, and the connecting mechanism is a back plate member. The through holes having the same diameter are formed at the same height position above each pair of leg portions of the plurality of frame plate members and the through holes of all the plate members above each pair of leg portions. A pair of penetrating shafts, a fixing mechanism for releasably fixing both ends of each penetrating shaft to the outer surface of the back plate member and the outer surface of the frontmost frame plate member, and plate members to which each penetrating shaft is inserted. And a plurality of cylindrical spacer members 5 that maintain the above intervals.
