How do you take care for a guinea pig in the winter?

you can make a box and put towels or nice soft fabric in it and attach it to the cage or you can make a bed with fabric in the corner of the cage also when you wake up if you are allowed go and get the guinea pig and warm it up also it might be shivering don't worry this is normal just do what i said and your Guinea Pig will be right good luck!!!!!!!!!!!!!!! -MissVanessa3434
