▶︎ To prevent any issues, please check my profile. Small Animal Heater Hot Usa-Dan Reversible Heater, Size M I used this for hamsters about 5 years ago to 3 years ago. I used it from outside the cage, so the hamsters never directly touched it. However, it has been handled by people, so please refrain from purchasing if you are overly concerned. The listed price includes shipping and handling fees. I have said goodbye to all the hamsters I had, so I no longer have any animals to use this for. I would be very happy if it could be of use to a small animal in someone else's home. I can combine this with other items I have for sale, so if you'd like to do that, please contact me before purchasing, or use the combined purchase option. (Details are in my profile)
