You will need an appropriate travel carrier (no cardboard boxes) The remainder of the fee (no personal checks) at time of pickup.
When you get them home. I suggest you remove all of the hides and leave one open hammock. Pick them up as often as you would like. Carry them around, in your pockets and in your hoodies. Put the hides back in, in about two weeks. The babies are used to be handled and in a new home they will be nervous but having them out in the open they will get used to you quicker.
I can offer some of my bedding I use and some food to send them home with if you would like. A pound of food for $5 A pound of bedding for $5
