Must a quarantine confinement chamber be enclosed on all sides except the top?

A quarantine confinement chamber must indeed have all sides enclosed to maintain a controlled environment for the animals inside. This is important for several reasons including preventing escape, protecting the animal from external stressors, and ensuring the safety of anyone interacting with the animal.

Having an open top could expose the animals to potential threats, such as other animals or adverse weather conditions, which could compromise both their safety and the effectiveness of the quarantine process. Therefore, it is essential for the chamber to be fully enclosed, with all sides secured, to ensure a proper quarantine protocol is followed effectively.
