My bunnies currently live inside but I'm having to move into shared accomodation and they will have to go outside. Its this or rehome them They currently have a small dogcrate and an attached pen thats 2metres by 1.2metres ish. What size hutch do I ned to be looking at? And where can I get one from? Funds are at an all time low, but I want them to have the best accomodation that I can afford.
