I am having a hard time finding one that looks right. Of course when you enter thermometer you will get thousands of chooses, then you have to narrow them by picking a category, and still I never find one that looks appropriate. I see some people with ones that stick on the inside of their cages. I managed to find two thermometers on ebay, however, they dont look like the apprpriate ones, however I still need one for my room anyway, so in actuality I need two, since the room adjacent to me is where my fur animals stay. Can you tell me what brand/name of thermometer you are using? The sticky has a link where to get almost everything to heat up a hedgie cage except a link for that. I am buying things little by little to set it up. Thanks in advance.
