Mine don't seem to be overly happy if I bring them inside for any reason. I guess they're used to being outside and their indoor cage is not a particularly big one.
I've always disliked the original hutch I bought when I got them so when I saw a 6ft rabbit hutch reduced in my local pet shop, I just had to treat them to a nice new hutch.
They've got a lot more space for toys and to run around. I've already seen them popcorning which they'd never done in their old hutch before.
