A true statement about ventilated cages is that carbon dioxide levels can rise inside the cages if ventilation fails. This is significant because ventilated cages are designed to provide a controlled environment for housing laboratory animals, including maintaining adequate airflow and removing waste gases like carbon dioxide. If the ventilation system malfunctions or fails, the air exchange that normally occurs is disrupted, leading to an accumulation of carbon dioxide, which can be harmful to the animals.

Proper functioning ventilation is critical for maintaining a healthy environment within these cages. It not only ensures that animals receive adequate fresh air but also helps maintain optimal humidity and temperature levels, as well as minimizing the buildup of ammonia and other harmful gases. When considering the overall care and well-being of laboratory animals, the efficiency of the ventilation system is a key aspect, making it crucial to monitor and maintain these systems diligently.
