I keep my leopards outside from May to early October sincce natural sunlight is much better for them. During the cooler months (I live in northern California) my leopards ar housed on either cypress mulch or a mixture of peat moss with sand and lizard bark. They need to have a basking temperature at ~90F with UVB lighting. Recently breeders believe humidity plays an important part in avoding tortoise pyramiding, provide them with a humid hide. I soak my leopards everyday or at least once every other day for about 10 minutes. Soaking ensures good hydration and they like to do their "business" while being soaked. I feed my leopards mostly grasses (Timothy & Bermuda, Blue Grass, etc.), clovers, dandelions, opuntia, endive, chicory, hibiscus flowers & leaves, no protein at all and very little to no fruit.
Good luck with your leopard, they make awesome pets!
