No leopard gecko should be deprived of hiding spots. Naturally nocturnal, they'll seek shelter from prying eyes when the sun's out. Get your gecko at least two hiding spots, and keep one of these internally moist at all times. Such a place will come in handy when the lizard needs to shed its skin.
Leos do well with a variety of substrates. Newspapers and paper towels are the cheapest options, but commercial "reptile carpets" and some ready-made, bioactive ground coverings work, too. Opinions differ quite sharply over the merits of sand; when lizards ingest too much of it — either accidentally or deliberately — it can be hazardous to their health.
OK, so what should they be ingesting? Leopard geckos are dedicated insectivores who fare best when given a steady diet of live mealworms and crickets. (More fattening bugs, such as wax worms, can be offered as occasional treats.)
Here are a few things to keep in mind:
- The insects your leopard gecko devours should themselves receive nutritious meals (like carrot chunks) before they're served up to the reptile.
- Lightly dust commercial calcium powders over the feeder insects. Without these supplements, your gecko may develop metabolic bone disease.
- Baby Leos need daily meals; adults feed every two to three days.
Complete your enclosure with small rocks and logs the resident(s) can climb around on. Also provide a shallow, sturdy water dish that's changed twice or thrice a week.
Leos aren't the most sociable beasts by nature. Even so, similarly sized females can be housed together without incident. Male-female pairings can work too — if you're prepared to handle their potential offspring.
But never, ever keep two males in the same container; they'll behave aggressively towards one another.
As a rule of thumb, you'll want an additional 5 gallons' worth (or 19 liters' worth) of cage space for every extra gecko.
Leopard geckos are generally docile and become quite tame with gentle, regular handling. (FYI: Don't grab their tails.) A Leo that's well provided for may live to see its 20th — or possibly 30th — birthday under your care.
