I found mine really enjoyed small cardboard boxes such as smaller cereal boxes. She enjoyed the paper towel roll when she was younger and outgrew them, but i just found some long square tubes for entertaining crackers that are just her size they make nice places for moss and elevated moisture, as well. Now when i shop, i am always on the lookout for containers that will suit her... I like the flower base idea as it it a nice shape they don't normally get.
