Lately ive been noticing that Eve is really not active at all, during the night i usually cover her viv with a black t-shirt or something. I was curious do you think adding newspaper balls to the enclosure would benefit her, although its been alittle more than a week since i got her and her stay in that viv. If it would, how do you properly do it.. cover the whole floor space? and should they be tightly crumbled or no?
