Since reptiles have metabolic rates about one tenth that of mammals or birds, thermal support is vital for ill lizards. It is necessary to maintain critical cases at the upper end of their [[Preferred optimum temperature zone|POTZ]] with a temperature gradient.

Since reptiles have metabolic rates about one tenth that of mammals or birds, thermal support is vital for ill lizards. It is necessary to maintain critical cases at the upper end of their [[Preferred optimum temperature zone|preferred optimum temperature zone (POTZ)]] with a temperature gradient.

[[Green Iguana|Green iguanas]] should be kept at between 30-38°C with high humidity. Desert species the same temperature but drier. Temperate species are kept at a slightly lower temperature. When information on the [[Preferred optimum temperature zone|POTZ]] is unavailable most ill reptiles will do well at about 32°C.
