"This species is a popular pet among enthusiasts. Some forms can be more irascible than others, such as M. s. mcdowelli and M. s. variegata. Forms that tend to be more even tempered include M. s. spilota and M. s. metcalfei. However this is not a hard rule. Although they can grow to a reasonable size (2-3.5 m) and can be nippy as hatchlings, most will grow into docile, trustworthy adults. However, care must be taken when feeding, as these snakes have a strong feeding response; behavior that can be mistaken for aggression. They can be fed on rats and mice and have a lifespan of 15 to 20 years."
