you should at least wait a week... what is with you and 3 days? it won't matter what your mom thinks of the fuzzy because fuzzies aren't weaned yet, so that's going to be a bit of a problem for you because it will starve to death if your snake won't eat it. Snakes can go weeks and months without food, so 3 hours isn't going to be a problem, put the top on, and step away from the enclosure, let it settle for a good long time (meaning a week or MORE) and don't touch it till it settles
