Baby, it's cold outside! As humans we need protection from these cold months but rabbits are quite comfortable in cooler temperatures, (within reason). If your bunny is kept inside, it will do fine with your climate control settings. If your bunny is kept outdoors, make sure your pet has plenty of bedding and a place for shelter from the harsh elements. Also, make sure to check their water daily to be sure it isn't frozen. Heated water bowles can be purchased at your local pet store to help ensure your bunny has an adequate, fresh water supply.
