My outdoor buns have tons of hay, heatpad, duvet, waterproof cover and a massive tarp over the whole run. But when I open the hutch every morning, Hunny hops out and finds the coldest and most exposed spot and stays there for most of the day! :roll: (Her husbun doesn't mind, he can sit right on top of the heatpad without being disturbed then :roll: :lol: )
