Ok there Ms. OCD.... Im kidding! I am pretty new at this too and I had done TONS of research prior to getting my first one. That was only 30 days ago and now I have 2. I can tell you that I am totally obsessed with this website as there is so much amazing information in here. I would really stress to you....read as much as you can!!!! Talk to other owners and read some more. There are some great books on BP's out there as well.

As far as the feeding I agree....try to feed what the store was feeding that is the easiest path. And if feeding live be sure to watch to ensure that the mouse doesn't bite your snake. Also it should be very quite and you might try making it a little more on the dark side.

I also am not sure if I missed how long you have had the snake. They say to put them in the enclosure and give them a week. Then try to feed. This gives them some time to adjust. This is the hard part.....when they are new to you....you should not handle them for at least a week. Some even recommend 2 weeks. This gives them time to adjust and become more comfortable. I know when you get a new snake you just want to handle them ALL THE TIME!!!

Ok....anyone out there please correct me if I have put any mis-information!

You might also want to read up on the shedding. There is some great info on here.
I can certainly attest to my first shedding with Elizabeth was VERY stressful for me.
