Basically the same as a larger one, but you MUST remember that because of their small size they dehydrate rather quickly, and the heat from the enclosure helps to dehydrate them. So moisture/humidity is their friend, and daily soaks in warm water.
I agree with Yvonne. Due to their small size, they are less tolerant to sub-optimal conditions. You need an enclosure that remains at 80ºF with 70% relative humidity, minimum. Dark places to hide and be out of sight and a balanced diet are all important aspects of the equation too. Yvonne is also spot on regarding dehydration - I used to soak my four redfoots every other day or two days when they were < 1 year old. Once they hit a year, they had to sort drinking out for themselves. Be sure you use a plant saucer or something similar so they can easily get in/out of the water dish. Best if it's flush with the substrate.
