I tried this with my bunnies hutches with irrigation pipe and drilled holes in it to filter out the pees and poops. The rabbits absolutely love it! It's nice and dark and they just chill in there as they see it as a safe and spot.
Mini ice sticks do swing furnishings, can be placed on the table as the decorations for people to enjoy, but also into the cage as a hamster mouse pet homemade toys, it is fun yo http://www.51feibao.com/ article-view-320.html
