All you really need is room for it. That is one of the most expensive parts (I think) of caring for snakes. The cage is relatively cheap, Petco sells then gallon tanks for about ten dollars, but the bigger ones are obviously more expensive and will be required. I currently have 2 wild caught animals (garter and anole) and have had many more (praying mantis, more anoles, etc.) and they are and have done fine in cages.
