Statement of Empiricism
I have used this heating pad for several years now (I wrote these instructions in December 2007, it's now February 2011). I have had exactly ZERO issues with it - it works perfectly and the hedgehog is fat and happy. YOUR MILEAGE MAY VARY! PLEASE USE EXTREME CAUTION IF YOU FOLLOW THESE STEPS. If you do this, closely observe the pad for at least a few days to make sure it's not overheating or catching on fire. See the obnoxious red text below:
USE CAUTION! TRY AT YOUR OWN RISK!
YOU WILL VOID YOUR WARRANTY!
So, I got this heating pad at the store a while back to use as a hedgehog heating pad. I found out that the 2-hour auto-off timer was hardcoded into the circuit, and they didnt even bother to put a switch on the casing to disable it. Typical overprotection of the consumer - this wouldnt exist if our country was a bit less litigious.
African hedgehogs need at least 72F to be happy, so a heating pad under the cage is recommended. I mean, how could you say no to his face?
So, to disable it, I decided to take it apart and find the culprit like this guy did. Its too bad that for some reason they decided to make it even harder to change this feature.
