I got up this morning and went to check the temps in the cage and the hot side was 75. I opened it up to check and the heating pad isn't working. So I turned the basking lamp on and that has brought the temp up to where it should be. I unplugged the pad in hopes that it needs a break. Do you always leave a heating pad on, or should you unplug it periodically? I have only had it since this past Tuesday, and have had it on the whole time. Thanks,
