This pet cage is constructed from treated Fir wood with weather-proof roofing.

There is a convenient hinge that holds the roof up too. The door is also a ramp and this design allows this hutch to be very compact yet efficient for its purposes. Not only perfect for rabbits, this hutch is also ideal for guinea pigs and other small animals too! Ideal for you if you have small animals and/or your pet just gave birth to babies.
