This is a corrogated cardboard bedding, pieces are about a cm. square.... on sale at around Â£6.50 or less... :-\ I've just been given some by a friend who is also experimenting her piggers on it too! I'm going to try it out tomorrow.... will let you know how it goes. I'm wondering if it might be a bit hard on their feet, but I could see that the wee's and poo's will probably just slip throught the layers onto the thick layer of newspaper. I currently use confetti shedded paper (and strip sheds with hay for warmth and burrowing pleasures)... But I'm constanly shredding every day to keep up with demand of change of bedding every third day... I've also considered a hemp style bedding or maybe a combination of the two to make it a softer bed for my lovelies! Any thoughts?.....
