You've gotten some pretty good answers so I won't go over everything. The one thing I didn't see mentioned is that it is perfectly ok to feed your snake 2 or more mice in one feeding. Feeding 2 mice in one feeding is generally preferred over feeding 2x/wk. You offer the first mouse as usual, then once he is totally done swallowing the first, and has reset his jaw, you offer the second.

I don't really recommend using google to search for answers to these kinds of questions. It can be very hard for a beginner to know what is good information and what isn't. Searching this forum is a good idea though. You have to be logged in to search, and you can find the search button on the dark blue bar (might be a different color depending on what theme you have selected) that starts with "Portal" "User CP" etc.
