PROBLEM TO BE SOLVED: To obtain the subject kennel having a comfortable environment for a pet and also capable of introducing a green thing having a charm into an inorganic life environment even a little by constituting it so as to grow a specific plant on its roof to improve heat insulating performance. SOLUTION: This kennel K for a pet is constituted so as to grow a small plant P having a high dry resistance on its roof. In this case, the inclination angle of constructing panels 2 of the roof 1 is preferably made as somewhat more gentle than that of the total angle of the roof 1, and it is preferable to install a soil stopper on the roof 1 for installing a growth medium of the plant P. Thereby, even under the direct sunlight, the inside of the kennel K does not become hot and is comfortable, and since the kennel K has a relatively low height, the plant P on the roof is seen by people and gives a charm to his life.
