That is so important- to give all new snakes time to settle in, learn their way around & relax without being handled & such. New snakes are stressed which impacts their immune system, so without this time to settle in, they're actually more likely to get sick from things they were exposed to along the way. And few pet stores have the space or time to quarantine new snakes, so they're often exposed to others that may be sick or carrying something they're not yet sick from. That's why it's much better to resist temptation & not interact with a new snake- it's much better to have them eating first, also. Their health is the most important thing.
