Pet rabbits love to live outside, and they can withstand moderately cold weather with their layer of soft fluffy fur and extra fat.
However, it’s still important to winterize your rabbit’s hutch if he’ll be outside as temperatures drop.
First, make sure it’s in good repair with no leaks where no water can seep in and no major cracks. You don’t want it to get damp. Make sure it’s water-tight.
Make sure your rabbit hutch is raised off the ground. If the hutch doesn’t have legs, place a brick under each corner. That will allow air to circulate and alleviate any dampness. If you experience excessive rain or flooding, make sure to move the hutch indoors or raise it well above the level of the water.
Reduce draftiness by covering mesh doors with a plastic panel. Look for panels designed for greenhouses as they still allow the hutch to be ventilated without letting gusts come in. At night, you can cover the hutch with a tarp or blanket, making sure to let an area away from the wind be exposed to keep air flowing.
Make sure your rabbit’s bed is warm and dry. His bed will be a box inside the hutch, offering him further protection from the elements. Use newspaper or straw for insulation in the hutch and in his bedding. He will burrow into it. A heating pad, turned to low, might also be a good option for your rabbit.
