I change the newspaper every 5 days, and reset that timeline after her shed vacuuming out all the left over pieces. I have not changed the humid hide's aspen digs. The digs were put in on the 24th. I would like to change those out every 3 weeks so i am going to switch that out on the 17th.
What I have to say about the box is that lots of people out there are saying do so for the pavlog's dog effect so that she will get use to being fed in a box and not her cage so they do not get nippy. I suppose in this case it is better to get her on feed for a while, then try to change things up.
