Litter trays, I only have to empty the litter trays every other day as I have two in there and plenty of megazorb, I do refresh the hay daily. They are pretty good at just using the trays although when I take out all the hay every other week there are a few maltesers but, not much at all, I do a layer of straw topped with hay and then add to that everyday for a couple of weeks and then completely change it, lino is good but, I'd personally cover the lot with hay when they are litter trained. My shed is basically a massive hutch :lol:
