During winter, how warm will the rabbit hutch stay inside?

An Omlet Eglu rabbit hutch will stay warm in winter weather. The Eglu is specially designed to keep your pet rabbits warm in the winter. Its unique twin-walled insulation system works in a similar way to double glazing, trapping a pocket of air between layers to keep the house well-insulated. The Eglu allows for airflow to prevent moisture buildup without drafts.
