Are you talking about the stuff you use to wrap your pipes in so they don't freeze in the winter?

Something like this? I don't see why not. Just put it on a thermostat and closely monitor it before using on animals.
The one you posted has a built in thermostat... nice deal for the $$. I'd consider adding a couple of probe thermometers just to make sure you're getting consistant temperature around the coil area.
