Is your leopard gecko's tank warm enough? Check your temperatures

A leopard gecko can't warm itself up or cool itself down, so you build the temperature map: a warm end, a cool end and a gentle drop at night.

Type in your thermometer readings and humidity, and get a quick green, yellow or red check on each one, plus what to change. Vet and keeper sheets differ by a few degrees, so the ranges show the overlap. Always ask a reptile vet about health worries.
