I know exactly what you mean as mine are the same, they live in their hutch outside. I want them to have a nice warm snuggly pace but I pad the bed bit with loads of hay, make a little burrow for them. I come back in the mornng they have flattened it all and poo'd all over it!
Don't really know what else to do. I suppose they must be quite warm in their main bit ( I put a cover over so the wind is kept out ).
I was looking at those cat beds for when they come in! They are gradually coming in more and more as they become better at bladder control. It is just a matter of convincing their Daddy! Bob was in his office all night last night while he was working and they were getting on well. Bob took himself up the stairs - So sweet. Maisy / Dave just sits around all the time!
