you can go to any pet store n get a heating pad. the heating pads are sticky on one side and alls you need to do is stick it on the outside bottom of one side of its cage/tank. make sure its on just one side so if your hamster gets to warm it can just go over to the other side where its cooler.
just put extra bedding in the cage-they can make some ridiculously warm nests from alittle extra bedding
as long as the house is kept at a comfortable temperature for the human inhabitants then chances are its also comfortable for the hamster
A heat lamp, rock or pad.
I'd suggest asking someone who specializes in hamster warmth.
As long as you are warm it should be fine
it is inside right?
Buy a heat lamp or heat rock from the reptile section of your local pet store
Keep it in the microwave.
Place it under your breast.
