It's important to remember that we are are a HOUSE rabbit site and community - which means most of us have our rabbits in our homes as their permanent living quarters even if they visit outside for play and exploration. We can help with suggestions for outdoor runs for supervised playtime.
We advocate bringing your bunny inside to live and we can help you plan and figure out the best way to do that. But if you plan to keep your bunny outside (especially in areas that have extreme heat or cold), though we can try and offer some safety tips and suggestions, this site may not be be best suited to advise you as only a very small percentage of our members keep their bunnies outside.
If you are interested in bringing your bunnies indoors to live we can help with housing, behavior, littertraining, cleaning, bunny proofing and more.
