very cute.
kiki I think the carboard has a walking hole in it so they can freely walk from the left to the right which might not be clearly visible on the picture. So it won't stop it getting any dirtier but it might hold a fraction more heat in so I'd leave it.
Another thing that looks deceptive is how high the heat plate is or if it is filled with wood shaving underneath, it looks like they are standing ontop with very little space for them to get underneath it but it might just be the angle of the picture. They should be able to get underneath it.
edit: is it even a heat plate?
