This 4ft Chartwell Double Outdoor Luxury Rabbit Hutch is the biggest 4ft hutch available for your small pets. It features nearly 2 feet of ceiling height on each floor and 2 feet of depth, making it an ideal starter hutch for small animals. It is important to give pets as much space as possible, and this hutch provides a comfortable living space. The hutch is treated with an animal-safe bactericidal wood treatment, but it is not waterproof. For optimal care, it is recommended to re-treat the hutch once or twice a year between seasons to prevent bacterial growth, as the water-based treatment is free of volatile organic compounds.
