I got two new snakes(had one for 2 days, one of 1 day) in the house right now....both have crumpled up newspaper in their enclosures....both took mice today...like emily said, the newspaper will stay until they have eaten 4 weeks in a row...then I will remove a peice a week until it is all gone... IMO...the newspaper allows them to fell 10x more secure and lets them settle down faster and with less stress.
