We have two rabbits. I would never ever entertain the thought of putting them in a hutch! When my daughter was born extremely prematurely and needed to come home months later on 24/7 oxygen, our buns who were previously house rabbits had to be moved out. I spent thousands on a bespoke shed - designed and built by a local company who built to our desired spec. It has a window, and after the structure was built we had professionals install heating and lighting. My partner spent weeks insulating it too. The rabbits live in a 12 foot galvanised steel 'puppy pen' within the shed. It was the best we could do for them under the circumstances.
It's freezing in the bunshed in Winter and the electric radiator costs a bomb to run (moreso this winter coming thanks to outrageous price hikes) but in Summer - especially in this extreme heat - its like a sauna. We've stayed at home for two days just to look after them. Providing them with a fresh bowl of water every 2 hours, 2 litre bottles of frozen water for them to lie against and lick the condensation from, all three(!) shed doors open (when the sun isn't on them) etc etc. We've been checking on the rabbits constantly, stroking their ears with tepid water to help cool them down. They've also had a tower fan on at one end of the shed (not rotating and outside of the pen so no cable chewing) so they can either choose to sit in front of it or not. They have coped, just, but I have been extremely worried about them, especially overnight when we lock the shed doors to protect them from predators.
The fact that people still keep rabbits in hutches absolutely baffles me. So many people get a rabbit (or rabbits - they SHOULD be kept in neutered pairs or small groups) without having the slightest clue about their welfare requirements.
For anyone who didn't already know, rabbits are no longer classed as domestic pets. They are grouped in veterinary terms with exotics because when cared for properly, they have very specific care needs and need specialist veterinary care when they become unwell. Rabbits are prey animals so often, by the time they display visible signs of illness or injury, it can be too late to save them.
It's devastating that rabbits locked in hutches cannot escape weather extremes or predators. Poor, poor rabbits. It's heartbreaking how so many people have them and don't care for them properly.
