Thank you all for the input.

I have spoken to another friend of mine, and she will come over and let them out to play for an hour or two once in a while, and I have one other person to ask. So they should be okay!
I already know how I am going to section off an area for them to stay in. They can be in crates during the day (they are used to that) then at night... I think I am asking for trouble ... but I think I am going to have my FIL gate them in our bedroom for the night. I mean hey... that's where they normally sleep!! But we may not have a mattress or blankets left when we get home. I think I may work for the first night... but after that, I think they may start to get mad!!!

WHEW.... I think I feel better!!
I can't believe how long I still have to freak out about all of this!
I can't stop thinking about it! I can't believe I am going to be leaving my babies for 4 days!!!!!

I know they are not going to eat!! The only time they eat... is when I mix up their food. Rick can mix up the SAME food... but they won't eat it!! Oh well.. it's not like they are going to starve! They'll eat when they are hungry!!!
