Yesterday I decided to give the buns a diggy box after reading about lots on here... I used the bottom of their pet carrier and filled it with shredded paper and hay. Big success, Honey, who lives digging, had a whale of a time making a big mess but now they're both using it as a toilet! How do you stop them doing that, or can you not? :? I don't really want to have 2 trays to clean every day when it's not really necessary!
