This cat house is made of “Shirake Mochi straw,” used in sumo rings, and is carefully finished by skilled craftsmen. An opening called a “cat window” is provided in the ceiling to ensure ventilation. It is well-ventilated even in summer, allowing cats to spend their time comfortably. In addition, since moisture is not allowed to accumulate, the straw is prevented from deteriorating and will last for a long time.
