Maybe it is uncomfortable. Do you have a hide in the cage, what is the tempature/humidity. Also do you open the cage alot or is the cage in a place where people walk past it alot.
I didn't see the full question so sorry if you said/answer all these things already.
Ok so I got the pad to about 91 degrees, the cold side is like 69 for some reason.. Humidity is 65..., and I cant find a light dimer at stores so I haven't been usin it I have a infrared though I just think it might be too hot
69 is a bit cold for ambient temp.. You can find a dimmer switch for the heat light from a hardware store or pet stores do sell them with dimmer switch on them already.. Or space heater to heat the room he/she is in.
If dimmer switches melted power cords they wouldn't sell them... Just wow... And the dimmer switch really has nothing to do with the cord it will have 120v av going threw the cord up to the dimmer switch if anything would heat up a little it would be the switch itself
