Heat emitters and bulbs aren't the only way to give your reptile heat - Heat cables allow you to create areas heat under your reptile's substrate, heating your vivarium or terrarium in the manner you see fit. Heat cable is flexible enough to wrap around, over and under objects to create a personalised heating system for your reptile.
As it only provides heating in the area it passes through, it does not heat the whole enclosure - you will always need some other, more broader form of heating for your reptile, but if you want to create pockets where your reptile can travel to in order to get some extra warmth, heat cables are great for that!
Heat cable technology can even become a functional part of your terrarium or vivarium decor! The Swell Heat Tree (available below) can be added to any dry setup to provide warmth as well as a climbing space for smaller reptiles.
