If you are bringing home a rabbit for the first time one of the most important decisions you will make is where and how to house him. Housing for your pet can vary considerably depending upon your home and your locality, but it has one universal requirement: rabbits need good ventilation. Without adequate ventilation, your pet can be susceptible to respiratory diseases. Keep this in mind when you buy or build a cage for your rabbit. Make sure at least a portion of the cage is constructed of wire mesh to allow good air flow.
