Why is it bad for rabbits to live indoors?

Please be careful when thinking about changing things around a pregnant doe, they can become stressed easily which can lead to problems, I moved my doe inside & the change stopped her milk & i lost all of my first litter. Im sure that some rabbits would be alright with being inside but it would be a big climate change for a fury animal. A rabbit should be more than capable of making her nest area warm enough for her litter, just keeping adding hay for her if you are worried. If she is used to inside before she gets pregnant or at the beginning of pregnancy then her body will have time to adjust. Hope this helps.
