I finally found what looks to be a good heating pad for pets. It runs off of 12 volts, from a wall transformer so there is no danger from the wires getting chewed or frayed. 12 volts can't shock animals. In addition the cord is armored anyway. The cover on the pad is removable and the pad itself is waterproof. It has a digital on off unit. It only uses 20 watts of power but supposedly can provide a lot of heat. I ordered on to try, it should be here anytime. The downside is that it comes direct from China so shipping takes a while.
Here is a link to it so you can get an idea. By the way, another plus is that it is a standard 12 volt transformer so if it burns out it can be easily replaced.
