Rabbits are usually kept in special cages known as hutches. These hutches are made with wire mesh, wood, or plastic, and are designed to provide a comfortable and safe living environment for the rabbits. Hutches are raised off the ground to prevent predators from attacking the rabbits, and they also provide good ventilation to help regulate the temperature and humidity levels. Additionally, hutches are designed to allow for easy cleaning and maintenance, which helps to promote good health and hygiene for the rabbits.
