Thanks for the reminder I didn't say anything about being cautious with any lab ratting--I think I'm careful; for this one I went for heating pads made in the U.S., UL approved for what it is worth, ones w/o an auto shutoff. No pins, no water, don't lay on them, smoke alarm, keep it on low, store flat, also make my own all cotton covers. Avoid bargain heating pads and only use them for one season. I guess I could use one that shuts off after 2 hr since I usually wake up enough every night to reset it.
Made in the US-for sure not in China-is a consideration of any purchase these days.
That bring up a question. Does the label "Made in USA" mean none of the components in an item were made elsewhere. For example a switch on a heating pad being made in China but the pad assembled in the US????
The heater for pipes get too hot-I have one in the pumphouse and checked it out.
