Heating pad problem! I think?

[ScubaSteve]

So I bought my female spider ball with her whole set up but i was not satisfied with the heat pad, so i got a bigger one (Flexwatt heat tape). I have it plugged into a thermostat and the temps are great. BUT i put her into the tub and i felt a funny vibration when she started sliding through my fingers. It felt like a tiny electric current. I looked into it and found that other people reported the same thing from personal heat pads. So I'm wondering if its affecting her? She seams to be acting normal... Any advice helps.
Thank you

If you are using flexwatt heat tape and you can feel a tingling sensation, somewhere you have an exposed electrical connection. Did you wire the flexwatt yourself? What are you touching when you feel it?

No i didn't do it myself, i got it from a reputable breeder in my area. I feel the tingling when I touch the snake itself

You really shouldn't be able to feel it through the plastic tub. The flexwatt isn't inside the tub is it? Do you feel it when you touch the flexwatt directly? Did the breeder solder the connections, or use a crimping tool?
