Reptiles are Cold Blooded and so it is imperative to provide them with adequate heating. Reptiles and amphibians also have specific lighting requirements depending on where they originate from. Of course reptiles need the correct light spectrum to synthesize vitamin D otherwise they can succumb to Metabolic Bone Disorder where their internal organs and bones become soft and brittle and will eventually calcify causing death. With this in mind please be sure to research your reptile first to make sure you understand what type of globes you need in your vivarium. Please research your species so that you know what temperature range you need to have set in your enclosure prior to obtaining any new reptile or heatinglight fittings. Pet City stock a wide range of heating pads and lights to cover the needs of all reptiles and amphibians in any size enclosure.
