Hi, My piggies are in a triple storey 5'x18'x18' hutch with ramps but to be honest get very little benefit out of all that space as they tend to stay huddled in one of the bedroom areas. Only one of them really uses the ramps, thr others are nearly always on one level. I have only had them and the hutch a few months but am already thinking about replacing it with a straightforward single hutch where at least they'd use the whole floor space. What size would be suitable? I don't think I'll persuade my husband to let me get a new one yet so better start saving! I don't really want a playhouse or shed at the moment as would rather wait til we move, although could maybe consider a small playhouse if it wasn't too pricey and could be moved.
