It depends where you put your rabbits cage. Also, both winter and summer affect rabbits. Read the one that affects where your rabbit currently is.
Outdoor Hutches:
Hutches are always nice to have in the summer, allowing your rabbit(s) to get fresh air.
Summer:
It can get pretty hot in the summer. Make sure you have two compartments in your hutch. One for Day, and one for the night. In the day section, you can have your wooden cage, than have metal bars or something like that so your bunny can get fresh air and you can see them. in the night section, just have it wood. Your bunny can go there to cool down.
Winter:
Ah, the coldest season. If you can, bring your bunnies inside if its -30. That is just too cold. Put some blankets in there, and tuck them in.
Indoor Cages:
There isn't too much to summer and winter here. In the summer, keep your bunny away from really sunny windows. There is a possibility it could kill your rabbit. Don't keep it to dark, either. Bunny will get scared. Night is an acception. Put it somewhere in between.
