From what it said on the website, these are bigger, tougher pads that can be used for larger animals like dogs. They are pretty pricey and they recommend that you buy a thermostat to go with the pad. That puts the price for the one I was looking at up to around $200.Are those reptile pads for the bottoms of tanks? They don't take turning on and off well. Theya re cheap but fragile.
