Ok so my silkies always sleep on the floor in the corner (an arrow pointing to where they sleep) by the door. They have been sleeping in the same spot since I got them. I leave the door open 24/7 and its getting cold and windy here so I dont really want them by the door cause I think they might get sick if they sleep there. So pretty much how do I get them to stop sleeping there? Maybe stacking something there so they have no choice but to move? What kind of nest or area do silkies prefer?
