A guinea pig cage is typically referred to as a HUTCH, which is a five-letter word. A HUTCH is a small wooden structure that provides a safe and secure environment for a guinea pig. It usually has an enclosed area with a wire mesh top, allowing the guinea pig to get fresh air while still being protected from predators. The HUTCH also has a sleeping area, food and water dishes, and a litter box. It is important to provide a HUTCH that is large enough for the guinea pig to move around in comfortably.
